Engine return Fire phenomenon

The reason for the engine tening: the mixture is too thin: it may be the failure of the oil line or the air intake system: the failure of the oil circuit is mainly caused by too little fuel injection of the fuel injector, mainly caused by too low oil pressure; the fuel injector is blocked. The failure of the air intake system is mainly caused by excessive air intake.

The incineration advance angle is too large: the main reason is that the crankshaft sensor (CKP) gap is inappropriate, or the CKP is loose, the temperature sensor is damaged, the engine load or the ECU is damaged.The deviation of the angle of the burning advance from the correct position is too large: the fault phenomenon mainly includes teaming and the sound of firecrackers, and when it is serious, it is mostly caused by improper insertion of the cylinder high-pressure pipeline.

Engine temping phenomenon: the reason may be the failure of the oil line or air intake system: the failure of the oil line is mainly caused by too little fuel injection of the fuel injector. The reason for too little oil injection of the fuel injector is: the oil pressure is too low; the fuel injector is blocked.

What's the problem with engine tening

Engine tening is also known as "backfilling", which simply means that the mixed gas after combustion is not discharged into the combustion chamber in time before and after the exhaust stroke, but runs to the intake pipe through the intake valve. Part of the fresh mixture was ignited, accompanied by a strange sound of "bang". Most engines operate normally, and the key processes are air intake, compression, work and exhaust.

The reasons for the engine temping are as follows: the mixed gas is too thin: the reason may be the failure of the oil line or air intake system. The main reason for the failure of the oil road is that the injection volume of the injector is too small, and the reason for the injection volume of the injector is that the injection volume is too low; the injector is blocked.

Posible causes of engine teming: thin mixture; there is a problem with the ignition system, the ignition advance angle is too large, and the ignition advance angle deviates too much from the correct position.The normal operation of the engine is divided into four steps: air intake, compression, work and exhaust.

This is what we call "bottom filling", that is, the tempering of the engine. The main reasons for car tenering are as follows: the mixed gas is too thin: the main reason may be the failure of the oil line or the air intake system. The failure of the oil line is mainly due to the small injection of the injector, and the excessive injection of the injector is mainly due to the low hydraulic pressure or the blockage of the injector.

What are the causes of the engine tempering failure problem

1. The common causes of the mixed gas is too thin. The common causes of air combustion ratio are: empty air flow sensor failure, abnormal throttle position sensor signal , low pressure of the fuel system, abnormal coolant temperature sensor, blockage of fuel injector, etc.01 The ignition time is abnormal.

2. The temping may be caused by the failure of the oil road or air intake system. The key to the failure of the oil road is that the injector injects too little fuel, which is caused by low oil pressure; the injector is blocked. The key problem of the failure of the air intake system is that the air intake is too large. The key reasons for excessive air intake are: the failure of the sensor that regulates the air intake; the air intake manifold leaks.

3. The reason for the engine temping failure: the mixing gas is thin: the reason may be the oil line or the intake system failure: the oil line failure is mainly caused by too little injection of the injector, and the reason for too little injection of the injector is mainly because the 3360 hydraulic pressure is too low; the fuel injector is blocked.

What's wrong with car engine tening

The reasons for engine tening are as follows: the mixture is too thin: the reason may be the failure of the oil line or the intake system.The main reason for the failure of the oil road is that the injection volume of the injector is too small, and the reason for the injection volume of the injector is that the injection volume is too low; the injector is blocked.

The ignition advance angle is too large: the main reasons are: the gap between the CKP (crankshaft sensor) is improper; the CKP is loose; the temperature sensor is damaged; the engine load; the electronic control unit is damaged.

There is a problem with the ignition system. The key to the problem of car engine temering is insufficient ignition energy (high-voltage wire resistance is too large; ignition coil is damaged; power supply voltage is insufficient) or spark plug failure. The key problem of the oil road is that the injector injects too little fuel and the oil pressure is too low. The fuel injector is blocked.

Engine tening is actually the intake pipe tememing: the intake pipe is due to insufficient oil supply and the mixture is too thin; if the mixture is too thin, the combustion speed of the mixture will slow down, and the combustion will continue until the end of the exhaust stroke when the intake valve is opened.

Engine temping, commonly said, in the cylinder, after the piston works, the combustion exhaust gas should be discharged from the exhaust pipe. However, due to some kind of fault, the exhaust valve has been closed, and the exhaust gas cannot be discharged, or there is no time to discharge the exhaust gas.

The tampering may be due to premature ignition and improper adjustment of the valve gap. The temperature is too high. The spark plug jumps too weakly. Insufficient combustion. Check the ignition timing, adjust the valve gap, adjust the temperature, adjust or replace the spark plug, and clean or replace the fuel injector. If it's a cannon, it's too late to ignite.
