Selection of NGK spark plugs by car brand. What are the features of Japanese NGK spark plugs, and how to select the right one for your car? Selection of spark plugs for the car

SPARK PLUGS NGK

The Japanese company NGK is the world's leading manufacturer of parts and components of ignition systems for car engines internal combustion. NGK has factories and their subsidiaries for the production of ignition system components in all parts of the world. Department of spark plug ignition systems and NGK incandescent Spark Plug organized 8 shopping centers, 11 production plants and 14 sales branches on all continents. These businesses are directly related to the sale various types car candles produced by NGK. NGK auto spark plugs are quite economical in price and provide good characteristics ignition NZhK auto candles are produced in various series. The NGK Standard line has a nickel electrode and inexpensive price. Iridium series NGK Iridium of various types with an iridium electrode of 0.6mm or 0.8mm with a price of 350 rubles and above can be used up to 100,000 km without replacement. Platinum car candles NLC Platinum of various lines with prices starting from 250 rubles are also quite durable.

Timely and complete combustion working mixture in the cylinder determines the efficiency and full output of the car engine. In a gasoline power unit, only a working spark plug will ensure this process. In the ignition system, this part is one of the elements that are subject to maintenance as a stand-alone operation. Before the next replacement, the selection of spark plugs for the car is carried out according to a number of criteria that will ensure stable and reliable operation of the engine.

Basic parameters and their meaning

When selecting spark plugs, the car owner does not assume the presence of a large number technical parameters and more often relies on the choice of a car service center or seller. At the same time, clarify the main characteristics of the candle a certain model is not difficult. Among the significant parameters are:

  1. Number of electrodes. In most cases, specimens are offered with two electrodes - central and one side. In terms of the quality of spark formation, such samples are not inferior only at the initial stage. Spark plugs with several side electrodes retain their properties for a long time, provided they are of high quality.
  2. Heat number. The indicator is taken into account taking into account the degree of forcing power unit. Samples with a low heat index of 11-14 are suitable for lightly loaded engines. Motors with output from 100 hp. With. per liter they work with cold (more than 20) or medium (17-19) heat values.
  3. Electrode material. The main material is alloy steel with the addition of nickel and manganese. The service life is increased by coating the electrodes with platinum. Fully platinum or iridium electrodes increase service life up to 100 thousand km, but increase the cost of the kit.
  4. Geometric dimensions represent several typical indicators.

The need to accurately select a candle in size is associated not only with the possibility of installation and good education sparks. For example, a sample with a short skirt will produce a spark off-center in the combustion chamber, which will directly affect the timing of ignition.

What does the marking tell you?

When choosing spark plugs, markings can give Additional information according to the characteristics of an individual specimen. For example, a Bosch product with the index WR17DDC9 is deciphered as follows:

  • letter “W” – the value of the metric thread on the body corresponds to 14×1.25;
  • designation “R” – the presence of a resistor to suppress interference;
  • index 17 – glow number of the candle;
  • consecutive letters "D"– the first indicates the thread length (19 mm), and the second indicates the presence of one side electrode;
  • the value “C” indicates the use of a copper electrode as the central electrode.

Before going to the store, we select suitable model based on the manufacturer's table, taking into account engine parameters. Specialized resources also offer a simplified search form, where the possibility of making a selection by car is considered.

Choosing a manufacturer

When choosing spark-forming elements, the choice is usually between the recommended elements for the engine or available analogues. Among the most famous brands With wide range stand out:

  1. Bosch spark plugs Over almost 90 years of history, more than 20 thousand models have been produced. Provided that original products are purchased, reliable engine operation will be ensured.
  2. Wide range of offers has a company called NGK, which has a history of almost 100 years. When providing High Quality the cost for mass-produced car models is around 100 rubles apiece.
  3. Candles Denso ignition provide the work of the world champion car manufacturer - Toyota. The number of cars produced in 2016 exceeded 9 million units, which only confirms the quality of Denso products.
  4. Widely known candle manufacturer Champion ignition known for the production of parts, including two-stroke engines with a high number of revolutions.

When choosing suitable option, it is necessary to take into account not only individual specifications, but also take into account the recommended replacement interval. At short intervals, there is no need to buy a spark plug with a service life of 120 thousand km. A high-quality product, for example, Finval or Brisk, will help ensure reliable sparking and optimal consumption fuel until the next service.

Replacement frequency

The regulations for replacing parts of the car ignition system provide for different frequencies of such operations. For the most common cars, this interval is set equal - Renault Logan (second generation), VAZ-2170 (Priora), Hyundai Solaris have a current indicator of 30 thousand km.

When planning the installation of new elements, it would be correct to change the entire set, without taking into account the actual condition of an individual spark plug. This will avoid engine trimming when running for a short time.

Among other signs of malfunction when a spark is formed, note:

  • noticeable increase in fuel consumption;
  • the appearance of vibrations in the operation of the power unit;
  • difficulty starting the engine;
  • failures when working in certain modes.

Online selection services

  1. Denso spark plugs, can be selected on that website.
  2. Look for Bosch spark plugs on this resource.
  3. You can find NGK spark plugs Here.

Exploitation modern car designed primarily for service maintenance. Therefore, the manufacturer does not always provide initial characteristics that will help you choose an analogue spark plug for your car. Even if Bosch presents such parameters, it will be difficult to use them.

In such cases, it is more convenient to make a selection taking into account the modification of the car. Usually it is enough to know such initial data as the year of manufacture of the car, the type and size of the engine, and the year of manufacture. If you have difficulties in searching on your own, entrust the selection of spark plugs by car brand to professionals.

These could be specialists from the nearest spare parts store, a specialized online store or a highly specialized service.

After processing the initial information, all that remains is to select the desired option from among the available offers, taking into account the product labeling. For example, for a not very common model, the Ford Explorer 4.0 liter, Bosch, Denso and VAG were able to immediately offer spark plugs upon request.

By vehicle serial number

Searching for spare parts by VIN code is carried out in cases where complete identification of the vehicle is required. This is true for rare modifications of even well-known brands, relatively new models.

The principle of searching by VIN is similar to how it works search engines on the World Wide Web. The encrypted information in the individual code is closely intertwined with similar codes for spare parts. Therefore, even without knowing the technical parameters, it becomes easy to recognize the desired candle.

For the search query by VIN code, some options are available:

  • specialized services searching for spare parts with a unique number task;
  • search resources comprehensive service online stores;
  • when contacting service center by catalog or search engines.

Before purchasing any set of candles, do not forget to visually check their condition.

The civilization of our driver’s handling of the engine goes back to the deep Soviet era, when the main mottos for car care were “a good knock will come out on its own,” “pull until the end,” “wire and duct tape will save the auto industry.” Culture develops over the years and is heavily dependent on the availability of spare parts, finances and, most importantly, knowledge. Maximum bottomless knowledge in every detail, every valve and every switch. Despite the fact that there are simply plenty of spare parts now and people rarely die of hunger, knowledge is simply a problem. Such a significant trifle as a spark plug can have such a strong influence on the performance of an engine, especially a modern one, that for many it will seem fantastic. Nevertheless, we will try to understand some types of candles, find out why, how much and what kind of candles are worth purchasing when next replacement.

Spark plug life

Like any device and device, candles also have their drawbacks. They are mainly associated with unstable and poor-quality sparking and low service life. On average, a candle can last no more than 30 thousand, which means that they have to be changed every 8-9 months. If this is not done on time, sparking and complete combustion will deteriorate. fuel-air mixture, so gasoline consumption began to increase and power began to decrease. And that’s not all, you can cite a dozen more negatives that are formed due to wear of the spark plugs. A candle, clumsily, is just two electrodes and an insulator. Again, roughly, the faster the electrodes burn out, the worse it is. Here the first contradiction arises. The fact is that the smaller the electrode area, the more powerful and intense the spark. The point discharge key is the most effective. A powerful spark is the complete and residue-free combustion of gasoline, tall Engine efficiency generally, high power at the exit. Therefore, designers look very closely at the material from which the electrodes are made, and until recently only nichrome could provide sufficient service life for the spark plug. It melts at a temperature within 1500°C, despite the fact that the temperature inside the combustion chamber always pulsates to 2.5-3 thousand degrees. Naturally, in such hellish conditions, nichrome electrodes will not last long and burn out with a frequency of 20-30 thousand km. You can fight this, but only by increasing the mass of the electrodes, or more precisely, their surface area, then burnout occurs more slowly, but sparking is also more sluggish. That is why manufacturers offer spark plugs with three side electrodes - they only affect the resource, and the spark that was there remains the same. Moreover, increasing the mass of the electrodes in some cases leads to elementary ignition gaps, since the spark becomes colder and is unable to ignite the working mixture. If speak about high speed engines, sports or busy, then a generally unsightly picture occurs. If normally the mixture still somehow ignites, then with a sharp increase in pressure, when the gas pedal is to the floor, its jump can reach 15-22 atm. from standard 5-8 atm. In this case, it is quite natural that the power will deteriorate, the amount of harmful compounds in the exhaust will deteriorate, and fuel consumption will increase. But a way out of this seemingly deadlock situation was found ten years ago.

NGK Iridium Spark Plugs

Why iridium and why NGK is explained quite simply. About 90% of all spark plugs that are installed on cars on the assembly line and 80% of the volume of all spark plugs on the aftermarket in the world are made by Japanese companies NGK and Denso. The latter is a subsidiary of Toyota, and the former cooperate with all leading car manufacturers. That is why they should be trusted in the first place, although this does not mean that Bosch or Brisk are worse. They are different. NGK opened the first candle factory in 1936, they found themselves in Europe after 1946, and today their candles are installed on the assembly line of Ferrari, Honda, Bentley, Rolls-Royce. Precious metals The company became interested ten years ago and today continues to study the use of noble metals in the spark plug. The precious metal is fascinating, first of all, because of its high resource. This is explained simply. Iridium has a melting point of 2454 degrees, platinum 1769, and nickel only 1453 degrees. The standard operating temperature of the spark plug does not exceed 700-900°C, and we have already complained about temperature changes and sharp jumps above. Consequently, the higher the melting point of the metal and the more complex the circumstances in which this metal is melted, the less likely it is for erosion, which means burnout of the electrodes. If so, then it is possible to make an electrode with a minimum area, and this will give a powerful spark. Thus, the diameter of iridium or platinum electrodes in NGK BCPR6EIX-11 and Denso VQ20 spark plugs is only 0.5 mm. This microscopic tip is fixed to the electrode by laser welding. It has already been noted that the smaller the electrode area, the stronger the electrostatic field that is created between the electrodes, the stronger more powerful spark, less electricity is needed to create a spark. In addition, the flame front on iridium or platinum spark plugs does not spread anywhere - the electrode has the shape of a cone and expands towards the base. But these are not all the advantages of iridium or platinum spark plugs. There is such a thing as self-cleaning of carbon deposits. As a rule, it begins in the temperature range of 260-300°C, and in candles using precious metals, additional removal of carbon deposits occurs due to a special groove between the electrode and the insulator. Another characteristic feature by which you can recognize NGK spark plugs is a V-shaped groove on the central electrode, which helps to shift the sparking front closer to the working mixture. The Denso ik20 spark plug also has poured recesses, but on the side electrode.

Correct selection of spark plugs for the car

Early or late, the moment comes when it is necessary to replace the spark plug, no matter how long its resource may be. Then the question of selection arises, since NGK produces a lot of models of iridium or platinum spark plugs. The brand of spark plug is strictly determined by the type of engine, or more precisely, the ignition heat number. A certain amount of heat is generated in the engine and it is different for each specific type of engine. So, an engine with a turbine can spin up to 7000 rpm, while for a regular VAZ engine 5000 rpm is the ceiling. Therefore, the glow ignition and the brand of spark plug must correspond temperature conditions inside the combustion chamber. Judging by the reviews, NGK BCPR6ES11 spark plugs performed well at VAZ. The lifespan of these candles turned out to be three times greater than that of a regular candle, but the price is consistently high - about ten dollars apiece. Economically, an iridium or platinum spark plug is still much more profitable than a regular spark plug, not only because of its high service life, but also because of the advantage when starting the engine in cold weather, there is no need to remove the spark plugs to clean them, the gap in such spark plugs is not adjustable, but remains stable.

Detailed video about NGK candles

When choosing spark plugs, it is very important to listen to the recommendations of the manufacturer of both the engine and the spark plug, and strictly follow the recommendations that relate to the brand, the gap between the electrodes and the tightening torque of the spark plug.

On this moment Japanese company NGK Spark Plug Co., Ltd. confidently holds the title of world leader in the production of spark plugs for almost all gasoline equipment: from small-capacity lawnmower engines to multi-liter trucks. NGK spark plugs are a “strong middle ground”; they are guaranteed to be able to withstand the specified parameters at the required mileage, without emphasizing any one parameter to the detriment of overall functionality. Therefore, NGK maintains its leadership in supplies directly to car factories. What is important to them is that “original” (i.e., purchased from a third-party supplier under their own brand) spark plugs do not cause any problems during service runs throughout the entire warranty period.

NGK TECHNOLOGY

The classic design of a spark plug seems to have remained unchanged for at least half a century. However, in modern conditions, when environmental requirements are constantly growing, such candles are of little use. The relatively large area of ​​the electrodes on which the discharge occurs requires an increase in voltage; the spark itself, “floating” on the surface of the electrodes, does not guarantee strict maintenance of the torque and speed of propagation of the flame front.

The V-Line technology developed by the company has become a simple and effective solution to the problem for most internal combustion engines. The essence of the technology is to apply a V-shaped groove to the end of the central electrode, running parallel to the side electrode. Denso also uses essentially similar technology, but to circumvent NGK patents, they make a groove on the side electrode.

For spark plugs made using V-Line technology, while maintaining other parameters, the area of ​​space in which sparking is possible is noticeably reduced. With the same ignition system, the electrostatic field strength between the electrodes increases, that is, the power and stability of the spark increases in comparison with traditionally designed spark plugs. In addition, the spark always jumps “from the edge”, where the spark gap is better ventilated - when operating on lean mixtures, this improves the stability of the engine, especially at idle.

NGK spark plugs with a semi-sliding surface discharge are interesting: unlike traditional multi-electrode designs, here the central electrode is completely recessed into the insulator.

The advantage of such products when working on rich mixtures or in worn-out engines: deposits of conductive carbon deposits here have little effect on the efficiency of the spark plug, and it becomes capable of working even with heavy contamination.

If we remember iridium spark plugs NGK ignition or platinum, their advantages over the classical ones are obvious: this is a much more stable sparking due to the small diameter of the central electrode, and minimal erosion rates - and therefore the longest resource compared to other types. No wonder in modern engines representatives of this line are installed already from the factory.

However, even here, NGK engineers found room for new experiments. The hybrid spark plugs they created have a central platinum electrode that works in tandem with a side electrode. The side electrode has a platinum solder and two additional electrodes that work on the same principle as is used in spark plugs with a semi-sliding surface discharge. When a spark plug becomes dirty, additional electrodes come into play, allowing the engine to operate stably until it warms up to the point where the carbon burns out.

DECODING THE MARKING OF NGK CANDLES

The products of this company are coded with a formula like 123456-7.

Let's decipher it for example NGK marking BPR5ES-11. It has a 14 mm connecting thread under the “21st” spark plug wrench, protruding insulator, conventional noise suppression resistor, heat rating 6, threaded shank 19 mm long, standard design, spark gap 1.1 mm. Let's carry out the reverse selection - let's say a single-electrode spark plug with a 10 mm thread for the “16th” spark plug has been removed from the car, the thread length is 19 mm, the heat number according to the table corresponds to the number 10 for NGK, the gap between the electrodes is 1 mm. Based on the known parameters, we are looking in the NGK catalog marked CPR10ES-10 (candle classic type, which corresponds to the parameters of the existing one) or as close as possible in labeling.

SELECTION OF NGK CANDLES FOR A CAR

However, this method is not very convenient. If we take into account huge assortment products manufactured by the company are the best NGK selection by car - this is the use of a company catalog, which is initially sorted by makes, models, years of manufacture and engine sizes. It is available on the company’s website both in printable form (in the “Downloads” section) and in an interactive version (in the “Product Selection” section). Find matching candles It’s not difficult here, even for the old Moskvich:

HOW TO RECOGNIZE A FAKE

The downside of popularity is the huge amount of counterfeit products on the market. To be convinced of this, you don’t even have to go to a car store: on Ebay or Aliexpress, type “spark plug” in the search, and it will immediately give you a huge number of candles in familiar packaging and, of course, from China. Such volumes of counterfeit goods have already seriously damaged the company’s reputation - in many car repair shops to this day, in case of any problems with ignition, the first answer is “You first install normal spark plugs, not NGK ones.”

So, how can you spot a fake on a display? Let's start with the packaging. The slightest “jambs” in printing clearly indicate a cheap counterfeit; the boxes of original candles are always perfect.

The workmanship itself speaks for itself.

The contact tip of the original NGK seems to be made in one piece with the spark plug: it is impossible to unscrew it with your fingers. Markings on the insulator and metal skirt must be clear and even. Carving on original products rolls, so it is always smooth and even. The roughness of the carving and the marks of the chisel indicate a dubious origin. Crooked electrodes, especially deviation of the side electrode from the central axis, is also a reason to refuse the purchase.

U fake candles V-Line almost always violates the direction of the groove in the central electrode - if at the factory, when soldering the side electrode, it is centered exactly along the groove, then with “basement” spark plugs their mutual orientation can be absolutely any. For candles with electrodes made of noble metals, since they are much more labor-intensive to manufacture, the differences from “singed” ones are even more striking, since it is unprofitable to fully maintain complex technology in the conditions of “left-handed” production.

A spark plug is a simple device at first glance. However, this structural element of the internal combustion engine is entrusted with one extremely important task– ignition in the combustion chamber fuel mixture. It is in the interests of the driver himself that the combustible mixture burns correctly, without side effects for the power unit. The quality and completeness of combustion depends precisely on the characteristics of the spark generator. The question inevitably arises: which devices are the highest quality and most effective today?

The Japanese company NGK occupies a strong position on the world stage, producing spark plugs for any modern technology. Many car enthusiasts believe that the design of igniters is ideal, but Japanese engineers prove the opposite year after year. NGK not only provides an extensive catalog of high-quality components for internal combustion engines, but also improves the technical characteristics of its products. Next, we will answer questions that concern many drivers: how to choose NGK spark plugs for the car and what advantages they differ from their competitors.

NGK spark plugs: description and main differences

Looks like car candles from Japanese manufacturer are no different from analogues: inside the ceramic shell there is a central electrode with a rod contact. And on the surface of the insulator you can find special recesses that prevent electrical leakage. Why then did NLC devices become famous and were able to win the trust of millions of drivers? Their popularity is quite easy to explain - NGK engineers take a responsible approach to the production of their products, paying great attention to quality.

These spark plugs are unique in their electrode, which is made of copper for better heat dissipation. It has a V-shaped notch that promotes potential distribution at the periphery. The heat-removing effect is enhanced by a special heat-resistant shell. The buyer has a choice of seven types of such products. The most popular and, according to domestic car enthusiasts, effective are igniters from the V-Line line. The product list also includes the following types of candles:

  • With one electrode - in the best possible way suitable for many modern cars;
  • Multielectrode – characterized by increased stability and reliability;
  • Iridium spark plugs NGK - the resource of such products is twice as long as conventional ones;
  • NGK LPG LaserLine devices are designed for power units running on gas.

Multi-electrode spark plugs are becoming increasingly relevant today. The side electrodes are capable of producing a spark, even if one of the spark generators fails. This principle of operation of devices provides more stable and reliable operation engine. Plus, the service life of NGK spark plugs with several electrodes is noticeably higher than that of analogues - about 50 thousand km. Iridium devices last for 100 thousand km thanks to soldering from rare earth materials. Many car enthusiasts prefer this particular product from the painting of products from the Japanese manufacturer.

Marking and decoding

All car candles from NLC received individual packaging and an identifier in the form of a special marking. Designations printed on the surface of devices greatly simplify the selection of a particular product. Basic knowledge of deciphering the markings will allow you to accurately determine the required igniter that is suitable for a specific type of engine based on its basic parameters. Let's decipher the marking using a specific example - BPR5EY - 11.

These symbols represent the following:

  1. B – thread diameter/hexagon.
  2. P – candle structure.
  3. R – presence of an interference suppression resistor.
  4. 5 – heat number (from 2 to 10).
  5. E – thread length.
  6. Y – design features.
  7. 11 – interelectrode gap.

Knowing the basic designations, using a special table you will not be able to make up special labor decipher the markings of any device. In this example, the NGK BPR5EY – 11 spark plug has a 14 mm connecting thread (B) for a spark plug wrench set to “21”, the structure includes a protruding insulator (P) and a standard resistor (R), the heat rating is 5, the length of the threaded shank (E) 19mm and standard design (Y) with 1.1mm clearance.

Selection of spark plugs for the car

Selecting NGK spark plugs by car make is quite simple and convenient. You just need to go to the official website of the manufacturer and go to the appropriate section - product selection. Then you just need to select required type engine - gasoline or gas-powered, enter the make and model of the car, after which a page will open with the characteristics of the power unit and a list of the most suitable this type engine products.

Selecting a car takes only a few minutes. For auto UAZ Patriot with engine code ZMZ-405, 409, NZhK offers standard BPR5ES spark plugs and upgraded BPR5EIX igniters to improve ride quality car. Also in the description under each product you can familiarize yourself with the main advantages and benefits of the auto candle.
