AT air filter motorists rarely look in and often recognize the ingress of oil particles only during a planned or emergency replacement this element. However, if oil is found in the air filter, then the owner needs to find the cause of the appearance and fix the problem.

Why does oil get into the air filter

The main reasons for liquid to enter the element:

• When the fuel is burned in the engine, it produces gases that enter the crankcase. At correct work car motor gases exit through the cylinders and through the exhaust system enter the external environment. However, if the engine is faulty or the wear is 50-60%, the gases enter the air filter and carry oil particles with them, which settle on it.
• If it is necessary to replace the piston rings, the oil enters the engine crankcase, into the ventilation channel and onto the air filter.
• If the hose used to supply oil is clogged, it is sent to the air filter along with gases from the crankcase.
• Can be clogged and pipe branch. AT this case oil travels with gases from the crankcase.
• A clogged filter can cause oil to get into it. Not enough air enters the car system, which causes engine malfunctions.
• High pressure in the engine and a clogged exhaust system lead to the fact that gases accumulate in the crankcase and engine, which travel through all pipes, including getting into the air filter and bringing oil there.
• The reason often lies in the wear of the seals. In this case, the oil consumption for the engine increases.

How to remove oil

The main methods used to fix the problem:

More often, the oil enters the filter along with the gases that pass through it. To solve this problem, you will need to remove the hose from the filter, rinse it from impurities and debris that clogged the element, and then install the hose back.
If this does not help, you will have to check the throttle valve. Soot and debris deposits often interfere with the correct operation of the spare part, which causes high pressure. More often, the problem is solved by repairing the damper or replacing it.

Slag can accumulate in the car's oil deflector; to fix the problem, you will need to clean this element and install an additional oil deflector.

If the air filter is damaged or clogged, it can itself be the cause of oil. In this case, the filter can be replaced or cleaned.

If the problem has not been solved, then the cause will have to be sought in the engine. This means that the car will need more serious repairs: replacement oil scraper rings or other types of manipulation.

Oil in the air filter nozzles often appears due to broken compression in the car's cylinders. You can check how the cylinders work by warming up the engine to operating temperature. If the values ​​are not the same, then the engine needs repair. Especially often this problem occurs in older cars.

The owner will also need to check the valve clearances. If they are too large, then oil will begin to appear in the air filter. The same goes for replacing seals. In a garage, it is difficult to determine the cause of a car malfunction. Most owners turn to a car service, where diagnostics are carried out by masters using special equipment.

If the machine's engine is worn out, you can delay the overhaul by:

• The hose that conducts gases through the crankcase must be removed.
• A plug is installed on the fitting.
• The crankcase is ventilated through a hose of increased length, it is passed through the bottom of the engine.
• Change engine lubricant.

But these manipulations will delay the intervention of repairmen by a maximum of 500 km. After that, the motor will need to be repaired or a new unit installed.

What threatens the problem

The presence of oil on the air filter itself will not bring harm, but it can serve as an alarming symptom that the need is approaching. overhaul engine, and this procedure is time-consuming and expensive. The appearance of a symptom requires prompt contact with a car service for in-depth diagnostics of the machine.

Key features

When checking engine compression, it must be remembered that a discrepancy of one or two units is acceptable. If the compression in the cylinders is very different from each other, then this indicates that the valves are burnt out or the rings are not pressed tightly, and it is time to change them.

It is worth paying attention to what color the car has traffic fumes. If the piston group is badly worn, then the smoke will acquire a bluish tint.

If, after checking the compression in the cylinders, no serious deviations from the norm could be found, then there is no cause for concern, and the oil most likely comes through the crankcase due to a hose clogged with debris. Hoses are easy to clean or replace.

See what can be done if oil gets into the air filter

Outcome

If oil is found in the air filter, the entire system should be carefully checked. Even if the car is new, this does not guarantee that the valves or rings are in good condition. The problem can be solved at the initial stage by minimal cost finances and forces, but the launched version will be very expensive to repair.

Petrol generator, he gasoline power plant one of the most complex small-scale mechanization tools. It consists of two components, this is the engine and the generator part (alternator). The motor rotates the armature, which together with the rotor produces voltage. But over time, malfunctions of one nature or another occur with both components.

The main malfunctions of the gas generator and their causes.

Generator engine malfunctions

Gas generator won't start Or it starts but dies. It's pretty common problem. Several factors influence this: spark, fuel supply, gas distribution mechanism, major mechanical damage (such as a hole in the crankcase or a broken connecting rod). sparks may not be due to a burnt coil, cap or candle. It is also possible that the sensor relay or oil sensor fails (cuts off a spark when the oil level is low), and there may be malfunctions of the wiring elements. Fuel supply the fuel system (carburetor, valve, filter, gas tank) is broken, the fuel system is clogged, the elements of the system (carburetor, valve, fuel pump) are faulty. Long downtime of equipment is detrimental to the fuel system. timing is responsible for gas distribution, large gaps and soot on the valves do not allow the engine to work efficiently, and sometimes start up.

The engine smokes. The main reason is the development of the piston group, oil from the crankcase enters the combustion chamber (the piston and cylinder are worn out). Too much oil also produces smoke.

The engine knocks. Development of the crankshaft, connecting rod, bearings.

Engine wedge. Also due to oil starvation strong production, soot in the combustion chamber.

Gasoline in the crankcase. Gasoline with oil flows from the crankcase. The carburetor is faulty, most likely the needle does not hold. Causes are wear or dirt in the carburetor.

Malfunctions of the electrical part of the gas generator

The gas generator does not produce current. The engine starts normally, but there is no current. The reasons are banal, the AVR burned out (the generator is not excited), bad diodes, wiring problems, problems in the stator or rotor, and individual modules fail (on some generators). On inverter generators, the main fault is the inverter board.

The gas generator produces current, but too strong or weak does not pull or connected devices burn. There are two reasons: the engine does not work at 3000 rpm (3000 rpm ~ 50 hertz ~ 220 volts), electronic components are faulty (ATS, inverter board, capacitors, diodes)

When connecting appliances, the engine stalls or does not pull- again, the problem with the engine. Something is clogged or out of adjustment.

Elimination of the main malfunctions of the gas generator on your own.

The main principle of the repair of any equipment is troubleshooting by elimination. How do we do it. A generator comes to us and we start checking:

• First thing inspect appearance on the subject mechanical damage and oil smudges, as well as the presence of rust in the tank. Next, we check the presence of oil and scroll the engine with the starter (look at the compression resistance and extraneous noise). Let's try to start.
• If not, look at the spark. Immediately we take a new candle (leaning the candle on the ground, we scroll the engine), if there is no spark or it is weak, we try to disconnect the wires from the oil sensor relay and replace the candle cap. If it doesn't help, look at the ignition switch or the power button. If everything is in order there, then the ignition coil is faulty.
• If there is a spark, try to run. If it starts and stalls or runs on a closed damper, the carburetor is definitely clogged. Many say that they cleaned themselves, but the symptoms are the same. This is obvious, you need to clean the carburetor by disassembling it to the bolt, by special means. And this is half the battle, then you need to install it and correctly adjust the rods and springs of the damper and speed controller. If it does not start at all, add some gasoline to the combustion chamber, through candle hole or an open carburetor choke.
• Rust in the tank- a very unpleasant problem, you can clean the fuel system and everything will work. But, soon, after a while, this rust will get into the carburetor (in the jets, under the needle) and the symptoms will recur. If there is rust in the tank, it is almost impossible to remove it. You can pour special means (such as a solvent) into the tank overnight or install a fuel filter, but the only salvation is to replace the tank.

The principle of operation of a gas generator is the conversion of the internal energy of fuel combustion into electrical energy. Actually, these devices can be considered mini-power plants. Components are the engine internal combustion and the generator itself. When rotating the shaft 2-stroke or 4-stroke gasoline engine there is a development required amount voltage that passes through the filters.

A variety of gasoline devices are inverter gas generators, hallmarks which is the presence of an inverter and a pulse-width modulation unit.

But, like any technology, power plants also break down. Below are the most common generator faults and recommendations for their elimination.

Problems with the internal combustion engine.

The reasons for this may be the following:

• The absence of elements necessary for the operation of the engine - fuel, oil, uncontaminated air filter. The presence of these components is the key to the good operation of the gas generator, in their absence, the protective mechanism is triggered and the device stalls.
• There is no ignition spark. You can fix the problem as follows: using a special key, unscrew the candle, then, using sandpaper and an iron brush, clean off the carbon deposits that appear when using low-quality fuel due to incomplete combustion. Then you need to wipe the candle with gasoline or alcohol, let it dry. After that, you should again check for the presence of an ignition spark and try to start the generator.
• Insufficiently adjusted carburetor, the occurrence of soot during generator operation is not in full force. Additional adjustment of the carburetor will help to solve the problem.
• Other serious damage generator.

Problems in the operation of an electric generator usually arise due to a lack of voltage that occurs due to a number of reasons. This may be a lack of contact, a malfunction of the brushes, burnout of capacitors, PWM blocks, etc. If voltage surges are observed at constant engine speeds, then most likely the matter is a malfunction of the excitation regulators. You need to disassemble the device to find out exact reason his refusal to work.

Difficulty starting the engine usually indicates a malfunction. To detect the cause in time means to prevent it. further development and stop the negative impact on the operation of the unit.

Often, several interrelated factors are the cause of the malfunction. In this case, they have to be eliminated comprehensively.

Most often, the circumstances that prevent the normal start of the engine are:

Poorly functioning ignition system. The following options are available here:

• Problems with the spark plug: too large or too small a distance between the electrodes (it is necessary to place the electrodes at the optimal distance), insulation failure (replacing the candle with a new one will help), the formation of strong soot (careful cleaning of the candle is necessary);

• Problems with the ignition coil: insulation failure or winding break (replacement is necessary), improper connection of circuit elements or interruptions in its operation (if it is impossible to eliminate the malfunction of the microcircuit, it must be replaced).

The air filter is designed to remove mechanical particles from the air. Due to the finely porous structure of the filter element, dust and dirt are retained on the filter, and the air purified in this way is supplied to the fuel-air system of the engine. The more intensively the generator is operated, the more air will pass through the air filter and, accordingly, the air pollutants in the filter material structure will be debugged more intensively.

Most generator owners greatly underestimate the importance of timely cleaning or replacing a worn out fuel filter. When the air filter is dirty, damaged or ruptured, it is unable to effectively clean the air, and therefore into the carburetor, and then directly into piston group dust will enter the engine, the abrasive properties of which will contribute to the rapid failure of the most important and most expensive generator components. Even a slightly contaminated air filter leads to a significant reduction in engine power, excessive fuel consumption, and as a result, to engine overheating and a significant increase in toxicity. exhaust gases.

When to clean the air filter in the generator

Most manufacturers recommend cleaning or complete replacement air filter every 25 hours of generator operation. This figure is only a guideline, as when operating in very dusty environments, such as construction sites or industrial environments, the filter will be contaminated much sooner.

The fact that the air filter needs to be cleaned can even be seen visually by the smoke content of the exhaust gases. If, with other unchanged factors - the quality of fuel and oil, the operating conditions, nothing has changed, the engine power has dropped, and the exhaust gases have become darker and more toxic, then, first of all, it is necessary to check and, if necessary, clean the air filter.

How to clean the air filter

Warning: Only the foam air filter should be cleaned. Paper elements or filters in the form of a cartridge must be replaced. Only in conditions of hopelessness, or, at least, low pollution, can you blow them compressed air or clean with a powerful vacuum cleaner.

The air filter cleaning algorithm is quite simple:

• Open the air filter cover and remove the sponge element from it.
• Using a clean rag, clean the elements of the inside of the case from dust, dirt and oil. It is strictly forbidden to start the generator with the air filter removed!
• If there is no damage, the sponge element must be washed under warm water, and then washed with dishwashing detergent several times until there are no traces of old oil and dirt on the filter. The main thing is not to use synthetic solvents or household chemicals to clean the filter. Most the best option- It's dishwashing liquid!
• If the sponge element of the filter remains intact after washing, it must be wrung out and dried thoroughly. If damaged, you must purchase and install a new filter element!
• A few drops of a new filter are applied to the dry filter. engine oil recommended for your generator. The foam itself is wrapped in a clean cloth and excess oil squeezed out with a few hand pressures. The rag with excess oil is removed and disposed of.
• The oiled air filter (a small amount of oil will contribute to a deeper air purification) is placed in the air filter housing in the reverse order with which it was dismantled.
• We start the generator and let it run for a few minutes. All cleaning of the air filter is over!

Checking the generator for noise

Phoenix Pro

If when turned on gasoline generator the muffler starts to shoot, there is a different noise and flashes are visible when popping, then let's try to identify possible causes of a malfunction of the gas generator:

First, the spark plug has failed;

The second cause of the malfunction is the incomplete combustion of gasoline in the cylinders;

Or not tight closing of the exhaust valve and the passage of burning fuel into the muffler;

downed ignition angle or valve opening, this gives flashes.

Repair Methods for Gasoline Generators

Fix the ignition of the gas generator (replacing the spark plug).

Clean or replace the air filter.

You can also check the tightness with which the valve is seated. In the simplest case, you need to unscrew the cover of the block head (when the outlet and inlet pipes are not screwed to it).

Check if the valve timing and ignition timing are set correctly. It can go astray from the working vibrations of the unit - the locking bolt that fixes the magneto is gradually unscrewed.

Disassembly

When the engine of the unit does not start immediately, you need to arrange a small technical inspection. Check the fuel level, the oil for the gas generator, the serviceability of the candles and the filter. It is unacceptable if the candles are dirty or cracked. Replace damaged ones, clean dirty ones with a wire brush. Remember that the generator must be cooled normally; when overheated, the power unit often fails.

If the voltage is completely absent, it is necessary to disassemble the gas generator and inspect it. In this case, several points can serve as the cause of the problem: lack of contact, malfunction of the brushes, burnout of the PWM unit, capacitors, etc. When the motor speed is stable, but the voltage constantly jumps, then the excitation regulator is most likely damaged.

Before you change a burned out block, you will need to find the exact cause of its failure.

Forced repair

Do-it-yourself minor repairs of gas generators, most often, are needed when candles, an air filter fail, there is no fuel and oil. Without them, most models simply will not start, as the built-in protection is triggered. Constantly monitor the condition of the mesh at the fuel filter and the cleanliness of the air filter.

A missing ignition spark can also be the cause of the problem. To solve it, unscrew the candle special key, with an emery cloth and an iron brush, clean the soot, wipe well with alcohol and dry. Then check for spark and start the unit. Please note that carbon deposits are deposited if low-quality gasoline is used, and also when the fuel does not burn completely.

You may still need to adjust the carburetor. Soot often occurs due to the fact that the generator is operating at partial power. big problems it is better to trust the experts. If you do not have sufficient skills, it is better not to try to correct them. We carry out repair of gas generators of any modifications.

We bring to your attention the information collected on the Internet on troubleshooting the gas generator (the table will be updated)

Generator malfunctions

Symptoms	The reasons	Solutions
At the factory, it spontaneously began to shoot from the silencer, with a pop, fire is visible	spark plug failure not complete combustion mixtures in cylinders incomplete closing (wear, burning of the seat) of the exhaust valve (passing the burning mixture into the muffler) knocked down valve opening angle, or knocked down ignition angle (when a candle flashes with a slightly open exhaust valve), which gives a flash in the muffler	replace the spark plug clean or replace the air filter check carburetor setting check the tightness of the valve to the seat (carried out differently depending on the design of the motor) in the simplest case, by unscrewing the cover of the head of the block (if the inlet and outlet pipes are not screwed to it), in any case, you will have to remove everything that prevents you from getting to the valves check the correctness of the valve timing and the correctness of the ignition timing (the ignition angle can also be knocked down from the vibration of the gene itself - unscrewing the locking bolt keeps the magneto in one position
The gas generator starts easily, but after a minute it warms up and stalls. and it repeats itself constantly. gasoline enters, air. filter clean		Check the oil level If there is a label on the generator with a level designation, fill up to the indicated level. When there is not enough oil. it works a little and stalls
The generator almost did not work in the working state there is no current		One of the main reasons is the excess of the starting current. Those. you could connect devices to the generator that, when started, consume more than the generator gives out.
After one year of operation, gasoline flows out of the air filter of the gas generator during its operation		It's most likely the carburetor. It could be clogged or oxidized. If clogged, try to clean, if oxidized, you need to replace.
Gas generator engine hour sensor stopped working		Replace sensor
I have a Genctab 2.2kW generator. Engine hours - 4h. During the next work, I exceeded the permissible load power (turned on pumping station 1.1 kW + another 0.8 kW). The generator has lost voltage, but the engine continues to run.		Diodes burnt out or winding burnt out
Wilmar wpg 6500 gas generator starts in a minute, stalls, then after 1 minute it starts up and stalls again		Check the fuel level, the most common reason is lack of fuel. If, however, he stood for the winter and the fuel did not drain, most likely you will have to change the carburetor
I bought a new gas generator and filled it with oil. Normally, it starts up for about two minutes, then it starts to work intermittently and stalls.		Check the petrol level
The Hyundai HY 3100LE gasoline generator worked fine. The tension suddenly disappeared. Measured, the output is 60-63 volts		Possibly burned out diode bridge or starter
I poured oil into the crankcase. The generator starts, but immediately stalls, the muffler fires. Drained the oil to the correct level.		Check candles
The generator began to drip oil from the exhaust pipe. Not much, but still annoying. Turns out normal without loss of power.		Check the compression of the engine, if bad then change the rings
