In severe frost, the engine may not start for the following trivial reasons:

1. Bad oil. - I pour TOKAI oil, Japan, in Vladik for 4 liters 1800 with delivery to Anadyr 2300, 0W30, zero problems.

2. Weak battery - Everything is simple here. There are no bad batteries, there is incorrect operation and a malfunction of the charging system (IMHO).

3. The ignition system is faulty.

4. Bad gasoline. - This does not threaten us - he is always bad.

5. Other not trivial reasons. Here is an algorithm that can be used to start a car in cold weather:

1. It's all about the oil. You can check the consistency of the oil on the dipstick. You don't need to be a great specialist to see that the oil has thickened too much in cold weather. Summer, low-quality or dirty oil that has not been changed for a long time can thicken too much. Don't be lazy to check the oil before you mess with the battery. If you are convinced that the oil in the crankcase is bad and there are big problems with replacement, there is a way to survive severe frosts. Consider it a forced emergency. ..If the oil is normal, the cause of poor shaft rotation...

2. It's a battery issue. It may be discharged or worn out. Before the onset of frost, it is recommended to charge the battery for at least 6-7 hours. If after the morning it still does not last, you will have to buy another one, even if this one is completely new. Batteries with ceramic plates (for example Warta) can die after just a few deep (full) discharges. The power of a battery is highly dependent on its temperature. If the battery worked normally in the summer, then by warming it up even without recharging (you can bring it home at night, if urgent, you can warm it up in a basin of warm water), you will achieve summer cranking efficiency while it is warm. …If the shaft spins well and there is at least one pop….

3. The reason is in the ignition system. The first thing to do is replace the spark plugs with new ones or calcinate them. Place on a metal stand on a gas stove and heat for 30-40 minutes. As a result, all the plaque burns off them, and the insulators turn white. If they remain red, the spark plugs should be cleaned by soaking in a rust converter for 1-2 days. Pay attention to the required electrode gap. You can even reduce it a little. For example, for 1.1 to 1.0 mm.. By unscrewing one spark plug, you can make assumptions about the starting problem: - If there are black (or very dark) deposits on the spark plug, the fuel mixture is excessively rich. -If there is no dark carbon deposit on the removed spark plug, we are talking about a lean fuel mixture or lack of fuel. BB wires. Those ends that are in the reel usually do not lose lubricant. And those ends that are put on the candles need to be lubricated with silicone grease or simply sprayed with VD. …failure to start in cold weather…..

4. from bad gasoline. THE MOST COMMON REASON! In our country, gasoline is most often diluted in two ways - either with gasoline with a lower octane number (cheaper), or simply with water. The mixture just doesn't burn. Moreover, it is difficult to immediately understand why the engine stubbornly refuses to work - the spark is excellent, gasoline is supplied, the shaft spins, and... don't start. In this case, the solution is to replace the gasoline with a known good one or add 2 times more good gasoline than what is left in the tank. .....about powerful starting transformers capable of spinning the frozen shaft of any engine. They can be used for a very limited time. If there are no “pops” at all, don’t “drive” the starter in vain - burn it out, but look for the cause of the problem. Five minutes of trying to start without “popping” with powerful cranking and “dry” friction is equivalent in terms of wear to a mileage of 500 km.

5. Other reasons: insufficient fuel pressure in the system, clogged injectors, frozen wet air filter, etc... any minor imperfections in the cold can become a big problem.

6. faulty starter. The Bendix either does not engage the flywheel or breaks off from it. Here you need to put the car in a warm place and warm it up, or put a fan heater under the hood and warm up the starter. It's definitely worth checking out.

7. Particular attention to contacts. Oxidized, loose contacts significantly reduce the likelihood of starting. For example, contacts of the battery, starter, generator, explosive wires, coils - ESPECIALLY, sensors, etc... In cans, as a rule, the PHASE and Oxygen sensor with Bosch firmware, in January the oxygen sensor is not to blame.

It happens that the lambda probe (oxygen content sensor in the exhaust gases) and the MAF (MASS AIR FLOW SENSOR) are to blame for the cold start problems of foreign cars. This is mistake. They start working only after warming up to operating temperature. But the air temperature sensor, in cold weather, gives the brain a fundamental signal about the desired composition of the mixture. Therefore, if the mixture becomes very rich, you can try turning it off or warming it in your hands - this also applies to basins.

Before starting, it is recommended to turn on the ignition several times without starting the engine and let the fuel pump work, creating the required pressure in the system. -if the battery is good and you spent the night in the cold, you can turn on the low beam for a minute and warm it up a little. -it is also recommended to depress the clutch pedal, facilitating the operation of the starter.

If the engine does not start on the second try, you need to:

1. Depress the clutch pedal, press the accelerator (gas) pedal to the floor.

2. Key in the ignition switch to the starter and 10-15 seconds. crank with the starter (the lower part of the spark plugs filled with fuel becomes dry). (This is not always understood by a car whose throttle cable is not adjusted correctly - it only applies to Foreign cars.)

3. Restart the engine. If you couldn’t start it 2-3 times, then stop trying and look for the reason. There is no point in running the starter and draining the battery. -No need to turn the crankshaft more than 3-4-5 revolutions. A break of 30 seconds to 1 minute is required between attempts. so that the fuel injected into the cylinders evaporates. Otherwise, the candles flood. There is no need to touch the gas - the brains do not understand this situation (this does not apply to basins). If none of the above gives results, there is only one way out. You need to drive the car into a warm box. And after prolonged warming up, continue trying to start - repeat everything again with basins - they will definitely start with a live battery without a garage.

About insulating the engine and battery.

Here everyone is doing their best, but I will not list what I have seen, I will simply describe what I have tried.

Insulation is definitely needed. The question is what and how should be insulated. Let's look at the analogy first.

If warm air is forced into a warm glass and turned over, then it can cool only due to heat transfer from the walls, and leakage and blowing will be insignificant. It will cool down within an hour...

If this glass is turned over, everything will blow out, and heat transfer can be neglected. It won't stay hot for a minute...

If the engine compartment is without cracks, including the radiator grille is TIGHTLY blocked by closed blinds, there will be nowhere for heat to escape except through heat transfer through the walls, just like from an inverted glass.

How to make such a glass?

We have one side hole - the radiator grille on the front. It must be closed so that the heat cannot escape to the side. These are blinds. They must be installed so that air cannot enter under the hood without passing them. Then, when closed, they will silently close the heat leakage to the side.

There is still a downward leak, but it is much smaller than the side leak.

After installing the blinds, it is necessary to eliminate the gaps at the hood junction. After this, it is better to glue the iron in a circle with a porous material and additionally apply a “blanket” to the engine. There are special heat-resistant capes for the “blanket”.

The traditional Russian “Cardboard in front of the radiator” is worse than blinds - heat will escape through the sideways cracks very readily and the effect of the “blanket” will not be so significant.

Experience shows that with shutters in the parking lot, the internal combustion engine cools down more than three times slower. In the presence of wind, the difference is even more significant. That is, during the night in cold weather, automatic winding will be three times less frequent.

Blinds should be automatic so as not to have to open and close them. But this is a slightly different topic, and with our frosts 7 months a year, we will focus on a simple radiator seal.

Initially, you need to solve the issue of preserving the heat of the battery and the most suitable and proven option over the years is a thermal case for batteries with automatic temperature maintenance (http://thermocase.ru/). Who organizes this depends on his means and assault.

Sorry for the plagiarism, but I once found it freely available from a motorist and did the same in addition to the thermal case for the battery - I’m happy like an elephant, and I wish you the same:

And so let's begin: Insulating the engine compartment is a complex thing.

You need to understand the ways in which heat escapes, and figure out whether simple actions, such as a car blanket or a piece of penofol felt, are enough to cut off these ways. A very good option is to measure the result using a thermal imager and confirm it with your own feelings.

Of course, not everyone does this or can ask the site manager Mikhalev from MP "GKH" to do this, but you can see the result of this approach using the example of someone else's car.

The photo can be seen at: http://www.anadyr.org/posts/kak-zavo...eresuuschemsya

Additionally, you can put blinds on the radiator grille, which in some modes simply must be open, and in others, on the contrary, when parked - the more tightly it is closed, the slower the car cools down. Window blinds will not work, but homemade ones made from tin cover the heating pipes, each covered with just the right fabric + a cable to the interior from a throttle valve from a UAZ from the Auto Parts store and a spring from an old folding bed.

Of course, many will find such a perversion unnecessary and Webast for 50 thousand rubles is much simpler, but not everyone’s monthly salary allows this, and some people just like to tinker with the car....

Good luck with Perversions.

Forgot about the errors:

1. Light a cigarette from the working car - the batteries should differ by at least 10 Amperes and not in your direction.

2. Battery from a working car to yours - like I’ll start it and give it away quickly with removal when the internal combustion engine is working - And brains are very expensive and if your car was produced and operated for a short time (from 2006 to 50,000 km) it can and will withstand or, on the contrary, it is so old that then the manufacturer was thinking about the reliability of a foreign car, and not about profit (until 1996) - good luck, but if you’re not sure - the brains for even the most worn-out basin cost from 5,000 rubles + delivery + something that is not available in Anadyr - setting....

Lighting rules:

1. Connect without mixing up the terminals.

2. Start the internal combustion engine of the working car.

3. A working car must run for at least 5 minutes to tune its brain (does not apply to cans) to an increased charging current.

4. Turn on and off the low beam of the car being brought to life for a minute.

5. Perform a test run (the batteries on both cars are connected as standard). A strong landing of the internal combustion engine of a working car and the reanimated one does not start - wait 10-15 minutes.

6. Repeat everything from step 1.

Urgently - disconnect the negative terminal of the battery of the car being revived (at the fear and risk of burning your brains and the benefactor if it is not a TAZ, which is also not an option), attach the launcher crabs and start from the working internal combustion engine at a speed of the latter of at least 2000. The plant is guaranteed if everything else is normal .

If the battery is still alive and the first start without an intermediary is not successful and you are not afraid to disassemble part of the car:

1. Let's go home for the most alcohol-containing adicolone (eau de toilette will not work - Chypre Deda is better)

2. Disassemble the air duct from the air filter.

4. Sprinkle the cologne and quickly close it - START - all about 10 seconds and the cologne should be at body temperature under the arm.

Hurray, we're up and running.

If not, wait for warming. Boil the Tea - pour it on the intake manifold, and other perversions like that, but let's boil the oil in the crankcase....

Gee Gee: This is often the end of the ordeal of many TAZ drivers (these lie under the TAZ not because it often breaks, but because the sound insulation is not good and any problems are immediately audible in the cabin, which can’t be said about foreign cars, it won’t fall off there yet and you won’t see your own wheel overtaking you on the highway, you won’t remember the wheel bearing) and owners of front-wheel drive cars, which cannot be said about all-wheel drive or plug-in drive.

You are happily sitting in a warm car, on the left is your wife, behind you is your mother-in-law and son, “Dreaming of not being late for school,” and the car either stalled when starting off or is driving as if your mother-in-law has gained weight to the size of an elephant....

Let's remember about the viscose coupling or rear axle. The latter just need to warm up the bridge with a burner, and better yet, without relying on a kind uncle who supposedly replaced all the oils in Japan, still carry out an inspection of the bridge in the summer. First - I never found the answer while I had a Nissan Sanka, until I ruined the viscous coupling in one winter with a sudden start from a standstill and removed the cardan with all the insides of the axle and........ I got a type of front-wheel drive Nissan. May you not be honored by such -42 degree mercy in the morning.
