How do you know if a car engine with one less cylinder out of 3 cylinders is not working?

1. If one of the 3 cylinders of the automobile engine does not work, there will be unstable idling, severe engine shaking, difficulty in starting, and even detonation at the exhaust pipe.

2. If a cylinder of the automobile engine does not work, the vehicle will also have weak acceleration, detonation, and stalling for no reason.

3. In the case of landing, you can try to pull out the high-voltage wire on the spark plug one by one, and turn off the fire when you pull it out, indicating that it is in the cylinder that is working normally; If there is no change after unplugging, it means that there is a problem with this cylinder.

Then check the two ends of the high-voltage wire on the faulty spark plug and ignition coil to see if there is any high-voltage electricity. If there is no high voltage, it means that the ignition coil is broken; If there is high voltage at one end and there is no high voltage at the other end, it means that the high voltage line is broken. When the high pressure is normal, it means that the spark plug is faulty.

The spark plug needs to be removed for inspection, and if the spark plug is flooded or damaged, it will lead to the phenomenon of cylinder shortage.

4. Check the fuel injector, if the fuel injector is blocked, it will also cause the engine to lack cylinders and idle unstable.

Check them one by one according to the above steps to find out the fault.

The superficial phenomenon is that the idle speed is unstable, the engine is shaking badly, and it always feels like the engine wants to turn off.

Proof of Inspection:1In the case of landing, you can unplug the cylinder wire on the ignition coil to see if there is high voltage generated.

2.Unplug the end between the cylinder line and the spark plug to see if there is any high voltage generated. If there is no high-voltage electricity, the cylinder is missing.

Such an inspection is to check whether the ignition coil and cylinder wire are faulty, and there is a spark plug, 3The spark plug needs to be removed and checked, and the spark plug is flooded or damaged, which will also lead to the occurrence of cylinder shortage.

4.There is also the fuel injector, if there is a head blocked and no fuel injection, it will also cause the engine to lack cylinders and idle unstable, but this situation is rare.

Landlord, do you understand?

It still works without a cylinder.

Can the car continue to drive if one cylinder of the car engine does not work? The answer is yes, the engine of the current car is generally a four-cylinder engine or a six-cylinder engine, and the lack of a cylinder can still work, but the overall working balance of the engine is broken, which will cause the engine power of the car to decline, the vehicle acceleration is weak, the body shakes and other problems, and the engine failure warning light of the vehicle instrument will also be flashing.

Regardless of how many cylinders the engine is, each cylinder is a device that generates power, it is independently injected and ignited, if one cylinder stops working, the other cylinders can still run normally, and the power will only decrease due to the lack of a cylinder that generates power. Of course, this is not a normal phenomenon and needs to be sent for repair in time.

The engine will not work for one cylinder, generally for the following reasons:

1. The spark plug of the automobile engine does not work and causes the lack of cylinder, because the spark plug of a single cylinder does not work, it cannot ignite the mixed gas injected into the cylinder, resulting in the failure of a single cylinder.

2. A single cylinder is not working due to the damage of a certain link of the ignition coil of the car, because the ignition coil can not conduct a sufficient voltage of current to the cylinder, the spark plug current is not enough to ignite, and the single cylinder will not work.

Can't open, the lack of cylinder shakes seriously, the car is weak, the cylinder that doesn't work only injects fuel and does not burn, gasoline will flow into the exhaust pipe, the exhaust pipe temperature is very high, it will ignite the gasoline, very dangerous.

Yes, it's just shaking, it is recommended to repair it quickly.

There are many factors for the lack of cylinder in the engine, such as the fuel injector of a cylinder is blocked, stuck, poor atomization, high-pressure oil pipe breakage, the working clearance of the intake and exhaust valves is too large or even broken, and the piston ring is broken and stuck, resulting in the cylinder or even cylinder barrel strain and leakage, and there are quite a few reasons.

1. Check the spark plug and the distribution line. Whether the clearance of the spark plug meets the original technical standards, and whether the resistance value of the sub-cylinder line also meets the technical requirements, if it does not meet the requirements, it needs to be adjusted or replaced.

2. Detect the fuel pressure system. Check the fuel pressure gauge and fuel pressure gauge assembly, connect the oil line and the oil gauge. Start the engine and put it into idle running, the fuel gauge reading should be in the range of 270 320kpa.

If the pressure exceeds the specifications, the fuel pressure regulator and fuel filter will need to be replaced.

3. Check the nozzles of each cylinder. Make the engine enter idle running, disconnect each fuel injector plug respectively, check whether its idle speed changes, if the fuel injector of each cylinder is disconnected, the idle speed reduction is basically the same, it means that the fuel injector is working normally.

4. When disconnecting a fuel injector, the engine idle speed and its stability have no change, it is necessary to measure whether the resistance value of the fuel injector plug is 10 13, and replace the fuel injector if it does not meet the standard. Of course, it is also necessary to check the wire between the PGM FI main relay and the plug connection point, and whether the wire between the plug connection point and the fuel injector is broken, poor connection and other faults.

5. Fuel pump and fuel pump circuit inspection. Check of the fuel pump: unscrew the fuel tank cover, when the ignition switch is in the ON position, the sound of the fuel pump running can be heard at the fuel filler port, under normal working conditions, when the ignition switch is on, the fuel pump should run for 2 seconds.

If the fuel pump is not running, first check whether the fuel pump safety has burned out. Check whether the PGM Fi main relay and the plug terminal are on, etc.

6. Secondly, check the pressure of the cylinder, the clearance of the intake and exhaust valves, the working condition of the fuel vapor control solenoid valve, the EGR valve block, and whether the intake manifold is leaking.

There are many reasons for the instability of the engine, so it is necessary to analyze the specific situation in the actual work in order to accurately find out the cause of the failure and the way to solve the problem.

Hello, it doesn't work and needs to be repaired, otherwise there will be engine shaking, weakness, and the three-way catalytic plugging, check the spark plug, high-pressure bag, fuel injector and cylinder pressure, I hope it can help you.

It will obviously feel that the power is insufficient, and it is not good for all aspects of the engine after a long time.

Lack of power and slow acceleration!

Whether it is a gasoline engine or a diesel engine, first of all, the operation is unstable, and then there is a lot of noise, a drop in power, and a decrease in economy, I want to know what kind of car yours, what engine, what fault causes the lack of cylinder? In order to give you a more reliable answer!

The second cylinder does not work and runs for more than 1,000 kilometers, will it hurt the engine of the start, which part will cause major repairs?
