The engine of Chevron Elysee is banging.

1. Step on the gas pedal and find that the acceleration is not obvious, there is no power, and the engine has hysterical sound. The most likely time is when the engine is hot, cold or short of oil. Of course, small displacement engines may also experience over-acceleration. I'm only talking about general displacement engines such as 1. More than five. The causes of such problems can be divided into air filter, spark plug, ignition wire, gasoline, gasoline filter, gasifier, oil pump and other problems. Check whether the air filter is dirty, whether the spark plug is old and needs to be replaced, whether the ignition coil is broken, and whether the gasoline is dirty, such as water in the oil circuit. And check the oil pump, carburetor and so on (if there is one in the car).

2. When driving, the acceleration is normal, and the ignition may be normal. However, if driving at a constant speed, it is found that the engine speed is too high, but it seems that the speed still cannot be raised. Try to check the coolant. If the oil pressure is too high or too low, check the oil pressure gauge. It is also possible that there is a problem with the ignition time setting, which will also cause such symptoms. As for the others, it may be an internal problem of the engine, such as EGR valve blockage.

The engine hisses, just like steam or air coming out of the engine. Generally, after hearing this sound, the engine will lose power quickly. Possible problem, engine overheating, check the cooling system. The exhaust system is blocked, and the vacuum tube leaks or breaks.

4. The engine will whir when accelerating, or it will appear when decelerating. In short, as the speed changes, the volume will also change. Possible cause: the power steering oil is insufficient and filled with oil. The generator bearing may be damaged. When there is a problem with the power steering pump and water pump, it will also produce similar noise.

There is a lot of noise in the exhaust pipe, which is very annoying. Sometimes similar sounds will come from the front section. The main problem is the exhaust system. Check whether the exhaust pipe is broken.

8. The engine has a kicking sound, like the sound of a pencil knocking on a table. When the engine speed increases, the sound increases. Possible cause: There is dust in the engine. It is recommended to change the oil, filter the engine and clean the engine. There may be a valve problem.

9. There may be no problem during driving, and there will be a click when accelerating. It is recommended to check the ignition time setting. The engine may be overheated, the engine may have carbon deposit, and the oil is not good, so it is necessary to add advanced engine oil.

10. Sharp noises, such as squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak. The belt is too loose, so tightening it can solve it.

1 1. When driving at a low speed, or when refueling the door, there will be a clanking sound under the engine, especially when the weather is cold. It is recommended to raise the frame and check whether there is an insulation board between the exhaust pipe and the ground. It may be caused by the aging of the insulation board, which can be solved by replacing or removing it.
