The car runs long distance engine alarm cylinder 1 alarm, several times! Getting sick after a long r

1.It is difficult to start when the cold car is started in the morning or the starting condition is unstable after starting, which may be accompanied by the phenomenon of stalling or the pollution lamp is lit, sometimes the engine shakes and the pollution lamp disappears after the ignition is turned off, and sometimes the engine shakes normally but the pollution lamp is on after restarting. The principle of the failure:

Basic principle: chemical energy is converted into mechanical energy.

2.When the engine starts cold, the cylinder wall and other parts of the engine are cold metal parts, when the engine is running, the fuel injection of the fuel injector into the cylinder is atomized, and the atomized mixture is encountered.

3.When the engine shakes, it means that the mixture inside the cylinder is not completely combusted.

The engine is definitely prone to problems when it works for a long time, and since it is alarmed, it must be repaired in time, otherwise it may lie down.

If you can rule out the problem of engine oil burning, it is recommended to go to a professional 4S shop for inspection and maintenance in time.

2. If there is a lack of two cylinders, the sense of sluggish shake will be very strong, the first and second gears can barely drive, and the third gear or more than 30 yards can not be driven.

3. For the whole vehicle, driving without a cylinder is like driving on a bumpy road, which will have an impact on the service life of the car and the safety of driving, as well as fuel consumption.

It must be faulty, you drive to the repair shop to check, don't drive a sick car.

It's better to do a maintenance first, just in case.

The car runs a long distance and the engine alarms, and the cylinder alarms several times, and you get sick when you run a long distance? I think the car should try not to go on the road with illness, especially engine failure, it is best to go to the car 4S shop for maintenance.

If you say this phenomenon, yours is a new car, then it is a fault, go to the 4S shop to test it, there must be something wrong, if your car is an old car, then the spark plug should be replaced, the lack of package, or the high-voltage package, or the high-voltage line, all need to be replaced, absent post, this is the phenomenon.

It can lead to unstable engine valves and clogged oil circuits.

It is possible to electroplate the valve top valve.

Influential. A cylinder of oil costs and produces carbon deposits. The engine is also weak.

Let's deal with it first, there is damage to the engine parts.

The first thing you will feel when driving without a cylinder is that the vibration of the vehicle is very large. It will undoubtedly cause damage to the engine gasket and engine mount. In addition, the engine behaves with a lack of power.

The machine, which was originally driven by 4 cylinders, now has only 3 cylinders to drive, which obviously shows a lack of stamina. If there is a damage to the engine itself, it is that the working cylinder and the working environment will deteriorate.

Four-stroke engine, mainly valve leakage, piston, piston ring and cylinder block gap is too large, cylinder gasket leakage, or due to the replacement of piston and other non-standard accessories resulting in a reduction in compression ratio and pressure drop.

The main reasons for the failure of insufficient cylinder pressure in the engine of the car are:

1. The engine overheating is caused by leakage and lack of water, and the engine is not replenished in time;

2. The piston ring is broken and the cylinder wall is scratched;

3. The piston pin clamp falls off and scratches the cylinder wall;

4. The piston ring is stuck in the ring groove due to carbon deposition and loses its sealing effect;

5. The piston pin goes out and scratches the cylinder wall;

6. Foreign matter enters the cylinder;

Failure phenomenon of insufficient cylinder pressure:

1.The inner wall of the cylinder is drawn into a deep groove, and the friction pair of the piston, piston ring and cylinder wall loses its tightness, resulting in the reduction of the compression pressure of the cylinder and the loss of power;

2.The downward channeling of the combustible mixture increases the pressure of the crankcase, which will cause the crankcase ** in serious cases; The lubricating oil is channeled into the cylinder, causing the phenomenon of burning oil;

3.Smoke from the exhaust pipe is severe; Abnormal engine noise; The engine does not work properly or even stalls.

Insufficient cylinder pressure indicates that the seal is not good. Check the piston and piston ring, check the cylinder head and head gasket, and check the valve and valve seat.

Just change the piston rings.

First of all, insufficient cylinder pressure will affect the combustion condition, and the phenomenon is insufficient power and torque. If it is caused by piston sealing, it will also cause serious carbon deposition in the combustion chamber and poor emissions. And the engine life is seriously shortened.

Piston rings are metal rings used to penetrate the inside of the piston groove, and there are two types of piston rings: compression rings and oil rings. Compression rings can be used to seal flammable gas mixtures in the combustion chamber; The oil ring is used to scrape off excess oil from the cylinder.

A piston ring is a metal elastic ring with a large outward expansion deformation, which is assembled into the annular groove with its corresponding profile. Reciprocating and rotating piston rings, relying on the pressure difference of a gas or liquid, create a seal between the outer ring surface and one side of the cylinder and the ring and ring groove.

There are many reasons for insufficient cylinder pressure, which may be the poor sealing of the piston ring. If the gap is too large, it may also be a problem with fuel, spark plugs, and ignition coils. However, this kind of problem is detected with a special instrument, if it can be seen intuitively, this problem is very serious!

Possible causes of insufficient cylinder pressure: broken or bent piston rings, spark plugs not tightened, valves not sealed, etc.

Fault phenomenon: insufficient power, engine shaking, weak acceleration, if the multi-cylinder cylinder pressure is insufficient or even unable to start.

The car fault light will suddenly turn on, and if the car fault light is on, it means that the severity of the problem can be large or small. Why? Because, sometimes the car fault light is not necessarily the fault of this component.

The fault light will light up when ignition.

When the ignition of the car is started, whether it is a faulty light or any other light, it will be lit and extinguished two to three seconds after ignition if there is no problem. However, if the fault light is still on, then it is necessary to pay attention, and the part that lights up the fault light may really have a problem.

The fault light of the new car is on, and it comes and goes.

As today's cars have more and more complex electronics, there are more wiring than ever before. Sometimes, engine failure lights and airbag failure lights appear. If there is no problem with these two after the inspection, then it is possible that the sensor is caused by poor contact, if you know where the sensor is, you can solve it yourself, you don't know you can find a professional repair shop to help you get it.

Can the fault light continue to turn on?

If you can't accurately judge whether it is a real failure, then don't take the risk, hurry up and overhaul it. Of course, if the oil alarm light, water temperature warning light, engine fault light, brake system fault light, steering power warning light, airbag warning light, tire pressure alarm, battery alarm and so on these fault lights are on, you still need to pay more attention, these are directly affecting the safety of the new car.

Generally, the fault light is lit to indicate the failure of the EFI system, and the computer needs to detect the fault code to know the fault point.

The engine fault light is not necessarily the engine failure, but more often some parameters exceed the standard value, such as exhaust emissions exceeding the standard, or for some reason the engine fires, etc.

Don't worry if the car fault light is on, these kinds of listen to how the old driver solves it, the method.

When the engine failure light of the car is turned on due to other reasons, I believe that many people also know that they must stop for repairs, but if in the process of driving, once our engine failure light is on, how to operate.

Don't panic, if it's yellow, you can drive for a while and then go to the 4S shop to check. If it's red, pull over and ask the 4S store if you want to continue driving or go directly to the 4S store for inspection.

Hello, the engine fault light is on means that there is a problem with the engine electronic control system, this has to go to the repair shop or 4S shop to solve the fault with a decoder**, in order to know what the fault is, if you have any questions, you can ask!

The fault indicator light is on, there may be a problem! You need a car computer detector, detect it, you can find out what the fault is, and then eliminate it according to the fault information, there is no other way!

Go to a professional repair shop to check the fault and eliminate the code.

If the engine fault light is on, there is no abnormal noise in the cabin, there is no other abnormal prompt in the instrument, the vehicle power is not affected, and the gearbox upshift is not affected, you can continue to drive and stop the 4S shop for further investigation, because the intake and exhaust may cause the engine failure light to be on, and the specific problem is analyzed in detail.

This is commonly referred to as the yellow engine fault lamp, also known as the EFI system fault lamp. As long as there are no special abnormalities in the engine power and sound, it can still continue to drive. Because there is a substitute bug program in the ECU.

Once one of the many sensors has a sensing failure, in order to ensure the normal operation of the engine, the ECU will replace the parameters of the faulty sensor according to the pre-set backup parameters to avoid vehicle breakdown. For example, if the water temperature sensor is broken, the ECU will use a backup value of 80 degrees as the control parameter for fuel injection and ignition. So it can be opened, but it must also be repaired in time.

There are two situations when the engine fault light is on: the yellow symbol light indicates that the engine is faulty, but the fault does not affect the normal operation of the engine, but it must be maintained. The red symbol light indicates that the engine has a serious fault, and it needs to be repaired immediately under normal circumstances, if it is in special road conditions, it can be used in an emergency, but it is necessary to pay attention to the working status of the engine at all times.

Hello, the fault light is on, you should find a safe place to stop the car and turn off the engine. If the water temperature warning light is on, the car can be idled to cool down; If the oil alarm light is on, you can pull out the oil dipstick to check the oil level; If the other lights are on, you don't know, drive to the nearest repair shop, use the diagnostic instrument to check the fault code, and eliminate the fault.

It should be that the compression pressure is insufficient, and the metal has a BAI characteristic when the weather is cold: thermal expansion and cold contraction.

When the cylinder shrinks, the gap between the piston and the cylinder liner is larger, and the compression force is insufficient. If it is difficult to start when the car is cold, it can be said that the compression force is insufficient. Another area where air leakage may be possible is the valve clearance.

If it is hydraulic, do not need to consider the valve clearance, start from the direct sealing degree of the valve to the cylinder, it is also possible that the cylinder gasket is flushed, the cylinder gasket will cause the oil to burn, the most direct way is to have about 10 minutes after starting to see if there is a faint blue smoke from the exhaust pipe, if it is definitely down. Just go and change the cylinder head gasket, be careful not to change it yourself, go to the repair shop to find a master to change it for you.

There are many reasons for engine fires, which are mainly divided into the following two aspects:

One is caused by the damage of external parts, mainly caused by valves, valve seat inserts, valve guides, spark plugs and other combustion chamber peripheral components.

The second is the misfire caused by the fact that the mixed gas in the cylinder cannot be ignited or ignited with a lag. In the first case, the spark plug is usually checked, and after the intake and exhaust valves are cleaned, check whether there is any problem with the supercharger and whether the supercharger impeller is worn or ablated. In the second case, it is usually due to the abnormality of a certain component or part, resulting in the unstable adjustment of the ECU to the engine, and the fire caused by the failure to reach the theoretical value of the ECU calibration.

There are a few other reasons:

1.At a certain moment, if the spark between the spark plugs is bad, there will be a lack of cylinder.

2.The self-inductance voltage of the fuel injector coil of a cylinder is too high, resulting in stagnation or poor closure in the next working cycle, which in turn causes poor working and fire of a cylinder.

3.At a certain moment, the instantaneous switch tube does not work due to the poor heating of the internal high-power triode fan, which causes the ignition coil or the ignition independent module to not work, and then causes the ignition.

4.The instability of modern integrated circuit boards and electrical components has led to many instantaneous failures, which cannot be explained, but the computer receives very few signals, so the computer can only refer to the knock sensor and crankshaft position sensor to calculate a certain fire.

The cause of the multi-cylinder misfire was bai.

1. Electrical circuits: du

1. Aging of electrical wiring, leakage, etc., intermittent ignition and internal cataracts;

2. Ignition coil or spark plug failure, poor ignition or poor conduction;

3. In terms of lines, loosening, breaking skin, etc.

4. Human operation reasons, such as carelessness or mistakes during maintenance: faults caused by touching, loose plugs, etc.

Second, the oil circuit:

1. The fuel injection pressure is not enough, and the electronic oil pump is faulty.

2. The oil pipeline is blocked or there are impurities, and the oil supply is not smooth.

3. Fuel injector failure, blockage or self-failure.

4. The fuel injection caused by the line is abnormal.

5. Other faults.

3. Engine.

1. Wear and aging, untimely maintenance, or the use of inferior, unqualified, substandard engine oil 2. Due to excessive wear, the cylinder pressure cannot reach the normal value.

3. Belt aging, ignition timing.

4. Distribution timing.

5. Intake section or throttle section.

5. Intake and exhaust valve and rocker arm assembly.

6. Defects caused by other places.

There are many reasons for the multi-cylinder fire of the car, and the following is an example of a gasoline engine

In terms of special power device lines:

a. Aging of electrical circuits, leakage, etc., intermittent ignition faults;
