Chery Fora 2.0 (A21) 4 doors.
sedan, 128 hp, 5 manual transmission, 2006 - 2010
- the engine is running
Main reasons for triplets
Incorrectly set ignition point.
- It is possible to adjust the air in the vacuum boosting system.
- Malfunction of the spark plug.
Warto note that this problem is the most widespread, because the spark plugs need to be changed after the car has covered 20,000 kilometers (this indicator should be included in the recommendations that the designers should give to the skin abundance).
- Break through the high-voltage shot that comes up to the spark plug.
- Capacitor malfunction.
- loss of system tightness in the area of ​​the intake manifold.
- One of the piston and valve has burnt out.
- Breakage of piston rings, their deformation and wear can also lead to the appearance of this problem.
- Incorrect adjustment of gas valves.
- A great step forward for the rocker. - Breakdown of the installed cylinder head gasket..
- Any type of wear (hardening, breakdown, ruination) of oil pans.
- If the carburetor is adjusted incorrectly, the cylinders may also be damaged.

- installation of a distributor shaft and a rotary plate bearing.

- smіchennya wind filter- Loss of tightness of the membrane of the vacuum regulator due to combustion. - Inspection of incorrect spark plugs (not only the size, but also other parameters of this element are covered) up to this engine. The engine is tripping

The triple engine is designated as soon as the failure is resolved

Why does the engine start to turn three?

The triple engine disrupts combustion in the cylinders, which is accompanied by a clear increase in vibration.
Please note that the appearance of vibration in the internal combustion engine does not burden the triplets, which is why there are few other reasons why the engines vibrate strongly.

The list of main faults, including three engines, includes: Supply of insufficient or excess quantity
firing at the cylinder;
supply of insufficient or excessive quantity of water;
malfunction of the ignition system, early or late ignition;
wear or breakdown of the engine, which is accompanied by a decrease in compression;
In other words, the engine starts to burn out as a result of the unusual combustion of the fire, untimely combustion of the fire or the possibility of igniting the charge, as well as the destruction of the minds of the normal fire of the fire as a result mechanical wear or breakdown of the engine itself. On the basis of this data, you can sound a number of systems for diagnostics. Start checking the trace

burning system

the injector, then the air supply at the inlet and the ignition system are checked. In some cases, the triple engine may be the result of a failure of one of the ECM sensors. The engine is in operation: the fire from the fire has been destroyed

The greatest
a common cause

, Because the engine is humming, there is late or early combustion, as well as a weak spark of the spark plug.
At the beginning stage, twist the spark plugs for a detailed inspection.
Since the spark plugs and wires are all the same, it is also the fault of the fact that there are three motors, the coil may be ignited.

On engines with large seals on the skin, this area is especially wide.

To check the heating coil, you need to unscrew the candle, apply it to the oil and start the engine.

Please note, cutting the candle may cause the oil to stick out a lot, the cup will cause a lot of stress on the candle.

Ignoring these rules can lead to damage to the cat or the switch.

A good spark with a characteristic crack will indicate the health of the coil, and the absence of a spark will indicate the need to replace the coil. As for the electronic ignition switch (switch), this element does not often break. To check the spark plugs, securely attach them to the ground, then connect the spark plugs to them, after which one person turns the engine with the starter, and the other evaluates the strength of the spark on the spark plugs.
Triple engine: problems with air supply

In this case, look at the sensor readings and make adjustments to the scanner, which is connected to the vehicle's diagnostic socket. Then the trace values ​​are equalized with the nominal values. Compliance with the norm in the readings of the povitrotratomer or position sensor

throttle valve

bring it to the point where the engine starts running.

Triple cylinder: the life cycle system is faulty
In the hour of revising the life system, pay attention to the following nuances:
Tisk paliva; view of the wind; The pressure of the pump must be dependent on the serviceability of the electric fuel pump, which is found in modern fuel-injected cars. fire tank.

The device's fuel pump strainer may be clogged, and there may be problems with the electric motor.

firing pump or by supplying life to the pump. Also, check the valve-regulator in the vise of the firing ramp.
Low pressure in the fuel supply system is often due to three reasons.

The next step will be to check the injection nozzles.

This element has the potential to become clogged, as a result of which the capacity of the building is reduced, the shape of the cutting torch is destroyed, and so on.

A loss of compression indicates a malfunction of the engine or its wear.

One or a number of cylinders are often not fully processed, so they are fed hot and cold, otherwise they are not pressed into proper order.

And there is no normal heat here.

Loss of compression results from burnout of pistons or valves, severe wear of piston rings and other defects in the cylinder head, cylinder head or timing elements.

In this case, it is necessary to measure the compression of the engine, after which the unit is disassembled for detailed diagnostics and repair.

Finally, I would like to add that the operation of an engine with a non-functioning cylinder is prevented, since driving with such a malfunction can lead to a whole series of additional problems, which is significantly more complicated and costly for future repairs.

If the engine operates unstably, such a phenomenon behind the cordon is called “mising”.

For our ears, the word is foreign and not everyone understands it. Enough motorists know what this is.

Mising - skipping the combustion of the burning mixture in one of the cylinders.

Inspection of high-voltage wires is mandatory when diagnosing the engine, if there are three.

They are not to blame for the breakdown.

The candle tips are clean and free of carbon deposits.

After visual inspection of the candle, turn over the high-voltage darts.

There is no need to trace the breakdown on them: black dots and dark. Do not reach the candle through the breakdown of the string. This defect is the immediate cause of the triple engine of internal combustion. Checking the wires yourself is not difficult..

Test them with a standard multimeter.

It is necessary to control the skin irritation. Video of checking high-voltage wires Check the darts with a multimeter.

Check the skin's base.

Engine loses power when cold

It gets stuck when the engine is running cold.

If you have reconnected and the spark plugs and darts are in order, then check the ignition module.

Since there are three engines, one or more cylinders do not work, do not rush to go to computer diagnostics.

Checking with a scanner will record a missed mark, but not the reason for the error. The cylinder is not working - it’s so obvious.

First go to a car service center, turn over the candles and darts.

The smell is most often the fault of the one with the three engines.

Missing.

Everyone knows this problem, only in folk-mechanical slang it is called a little differently.

If one cylinder doesn’t work, what should I do?

“Three engines” - this is what the malfunction itself is called, if the engine does not work.

There will be problems if the two cylinders are not working properly.

Ale is even rare.

Let’s take a good look at the situation with this, if one cylinder is not working.

More importantly, the reasons for the malfunction, their thoughts and assumptions, however, should be raised to the situation if two cylinders are not working.

What signs do you know that one cylinder of the engine is not working?

It's simple.

Find out the reason for the bad cylinder

The remark is that the verification and search for reasons is carried out in the minds of the garage.

• There are two options: mechanical and electrical (fired). To begin with, you need to take the easy route, and then start with the diagnostics.

• The candles are lit. This means that it is a matter of practice in the old way. Visually, the original electrode and insulator appear to be light brown, but not black with carbon deposits. We can talk about sooty electrodes either about the overly rich sumish or about those that are smeared with oil.

• Іskrotvorennya. By inserting the spark plug into the cylinder head, bring it to a distance of 1-2 cm from the cylinder block and carefully turn the starter.

• If the spark “jumps”, then the spark plug will blow up, or change it. High voltage darts.

• We check them for the presence of mechanical defects. We check their tips.

• There is a light gray color on the tip of the VR dart, which indicates that the robot is in extreme mode. The BP wires are checked with a multimeter. On different engines

The difference is the difference between the BP wires and the different support.

Good luck to you with the identified cause and the suspected malfunction of the non-performing cylinder.

If the engine has “three” and does not work on one of the cylinders, then there is a clear “boo-boo-boo” sound - the engine does not sound the same as before.

Let's figure out the main reasons and how to correct the situation with our own hands.

Like inheritances If the engine “trips” and shakes, it begins to wear out quickly. As a result, the compression changes, creating pressure to create scuffing on the cylinders and pistons.

The motor begins to work differently

temperature regime

starts to overheat. Sometimes it turns out that everything has been checked, but the engine is still “three”.

Therefore, point by point, it is recommended to review the procedure for diagnosing in ordinary minds, if there are no special devices, in order to look in the middle and accurately identify the cause.

• Vinny candles ignited
• First, unscrew the spark plug from the cylinder and look at it respectfully.
• What do we need?
• If the engine is operating correctly, the color of the barrel electrode and insulator will be light and slightly brown.
• Such a candle is lit.

If there is a lot of carbon deposits on the black color, this is the reason why the engine can run unevenly.

Let's get rich with burning oil or sprinkle with olive oil. Cause soot: the robot was running at idle and in warm-up mode;

engine compression is reduced;

disruption of gas phases;

incorrect injector operation (nozzles are clogged with debris); The robot sensor is incorrect. ignition - well, let's skip this point.

Now let’s take a look at the tip of the dart that is inserted into the candle.

It is due to the use of a monochromatic color and not to the appearance of a layer on the inner surface and points of the ring.

According to the given reasons, the high-voltage wire was operating in extreme conditions (faulty machine spark plug, excessive gap), which caused the malfunction.

Pouch - replacing the wires with new ones.

If you don’t always have the courage to change the color of the middle of the tip of the high-voltage dart - then test the wire.

• To determine the value of high-voltage equipment, we rely on the help of a digital multimeter.
• The values ​​may vary for a particular engine, but may exceed the value of 20 kOhm.
• If one of the wires shows significant support, it means that it is faulty and this is the reason for the interruptions in the work.

It appears that the high-voltage darts are mixed up.

This is true because the coils are marked with numbers that indicate the number of the cylinder on which it is working. But you don’t know everything, because the stench is terrible to read through the brood. On machines, the cylinder numbers are written on the igniter, which requires cleaning the lid and will immediately become visible.

Malfunction of nozzles and injectors

The engine can be tripped through the injector or there is a malfunction of the injectors in the following situations: Malfunctions of the injector itself (occasionally sharpening); As a result of the vicissitude of non-acidic burning, the stagnation of “purifiers of the burning system”;

One of the most common engine malfunctions is interruptions in the operation of one or several cylinders, about which motorists say “the engine is in trouble.”

Everyone who has dealt with this phenomenon singly knows its symptoms.

Not all car enthusiasts know the causes and consequences of such a breakdown. Today we understand why three engines are needed to diagnose and repair the engine correctly. Reasons for which engines are “three” Three motors can operate continuously or intermittently. The main signs of the triple engine are as follows:

idle speed

• Strong, uneven vibrations begin to penetrate from the engine compartment into the cabin, the sound of the operating engine changes (it “gurls”, moves from high “notes” to low ones, and back).
• The unit begins to experience more heat, and its tension decreases, and
• exhaust pipe
• lewd obscene sounds, accompanied by a thick smoke of white and black color.

If you want one of these signs, it means that the “heart” of your car has problems with one or more cylinders.

If you don’t put them down right away, the results can be even worse – down to the power unit. We characterize the widest range of reasons for the three engines:

late or early onset of feverish fever (TVZ);

uneven radiation is burning into the engine cylinder; failure or excessive heat in the combustion chamber of the cylinder; Reduced compression level.) or the valve is pressed on the fuel supply system. As the cylinder consumes more, less power, the problem arises in firing nozzles

- The stench became confused or went well. I guess, another “poor” reason for the triple engine is a failure of the electronic control unit (ECU) of the power unit, which can be slightly increased or the supply of gasoline/diesel to the cylinder changed.

Reason #3

. Excess air in the cylinder is a sign of depressurization of the air supply system, which includes the air filter, intake pipe hose, throttle pipe and receiver. A small amount of the important component of the combustion mixture in the cylinder may be caused by a clogged air filter or breakdown of the throttle valves. If the engine is damaged or the throttle position sensor is damaged, which the ECU detects, it can cause the engine to supply or change the flow rate into the combustion chamber, which can also cause a triple engine failure.

Reason #4

.

Low or high speed, perhaps, is the most important reason for the engine.

This is a sign that the pistons or valve in the non-working cylinder have burnt out, or have worn out completely. This means there is a problem cylinder.

Checking the operation of the cylinders is carried out with the engine running, so it is necessary to ensure all safety checks.

We turn on the ignition, open the hood, and listen to the engine. It is remembered what sound it makes.

The high-voltage darts begin to be removed one by one to reach the spark plug.

When the working cylinder is switched on, the engine starts to operate with double the force. When the spark plug is turned on on a non-working cylinder, the engine behavior does not change.

Another method is to not consume the high-voltage particles, but instead to turn on the chips that supply hot water to the injectors to the cylinders. When one of the robot chips is connected, the motor does not change - so a junk cylinder is clearly visible. Croc 2.

Since it is low, then, melodiously, the elements of the firing pump or the vice valve in the firing supply system went out of tune. If it’s normal, we check the injectors, they can get confused or go out of order.

Finally, we check the operation of the firing system using diagnostic equipment - possible corrections in the ECU.

Krok 5. The compression in the cylinder is measured using a compression meter, which is inserted into the spark plug hole of the problem cylinder, including the ignition and moving the engine wrap. The display can be taken several times. If the compression has dropped by 15%, the piston, valve or piston rings have worn out in the cylinders. If a breakdown is indicated, the engine will have to be taken apart. How to make money so that the engine doesn’t waste Having carried out the diagnostics and determined why the engine is in trouble, we proceed to correct the situation.

Well, if the problem is only with spark plugs or high-voltage motors, they can be solved.

The same thing - about the coils and switchboards.
