The diesel engine makes a sound as soon as it is refueled? What is the cause of the clatter of the d

1.Insufficient oil supply The amount of oil in the cylinder is small, the heat generated by combustion is reduced, which cannot meet the needs of the engine load, resulting in engine weakness, making the combustion insufficient and emitting black smoke.

2.Poor spray quality When the diesel engine is working, the injector spray quality is poor, resulting in a small surface area of fuel injected into the cylinder, a reduced binding rate with oxygen, and less heat emitted.

3.Too little air intake The engine is not fully charged, resulting in the carbon atoms in the fuel not being able to react adequately with the oxygen atoms, so the heat released is reduced.

4.Effect of ambient temperature: If the temperature is too high, it will cause the engine to overheat, which will affect the inflation capacity of the engine and make the engine power.

If it is sudden, it should be due to a lack of oil. The problem is that the noise comes from the diesel engine. If it's coming from the combustion chamber, it could be that something got into the cylinder or hit the valve. Is there a sound in the trunk?

If it is sudden, it must be due to a lack of oil. The problem is that the noise comes from the diesel engine. If it's coming from the combustion chamber, it could be that something got into the cylinder or hit the valve. Was there a sound at the beginning?

In general, when the car starts cold, the engine sound will be slightly louder than when the car is hot, as long as the sound sounds uniform and soft, not harsh, there is generally no problem. This is due to the fact that the gap between the cylinder wall and the piston is not yet optimally sized during cold driving, and the lubrication of the oil is not sufficient. Usually when the engine block temperature reaches about 95 degrees, the sound will return to normal.

The reason for the engine oil, the inferior oil or the oil has not been changed for a long time, the lack of engine oil, etc., can easily lead to increased friction between the valve and the guide and the hydraulic tappet, etc., so that the various sounds in the engine are louder.

Precautions for diesel engines.

1. Check whether the water tank is full of water, and check whether the antifreeze is full in winter; whether the oil is at the specified oil level; Whether the diesel tank has sufficient diesel.

2. Check whether the wiring of the electric starting system circuit is normal and firm, whether the liquid level height of the battery is normal, and whether it is kept between 24V and 26V.

3. Check whether the transformer switch in the high-voltage power room has been disconnected, and whether the mains incoming switch in the low-voltage distribution room has been disconnected.

4. Check whether the incoming switch of the generator in the low-voltage electric room and all the shunt loads powered by the generator are in the disconnected position.

There is a clattering sound in the engine, which may be caused by the following reasons:

1. Abnormal noise of engine belts, such as generator belts, air conditioning belts, steering pump belts, etc., may be too loose or too tight, or it may be that the belt is aging, adjust the tightness of the belt, apply butter to the belt, or replace the belt.

2. The engine lacks cylinders, a cylinder does not work, the engine will be unbalanced and produce abnormal noise, and it is also accompanied by the violent shaking of the engine, insufficient power and other faults, which may be the fault of the ignition module, spark plug and fuel injector, and the corresponding accessories can be replaced.

3. Engine "tempering" failure. When the car slows down and collects the oil, there is a "poof" sound, which may be the engine "tempering" failure, which is usually called the engine "fire", too much carbon deposition on the valve or the wrong timing of the valve will produce abnormal noise, cleaning the carbon deposit on the valve or adjusting the timing of the valve.

Summary. Hello, it is normal for the diesel engine to clatter when it is refueled, because when the diesel engine is cold started, the engine sound will be slightly louder than when the car is hot, as long as the sound sounds uniform and soft, and it is not harsh, there is no problem Oh I hope the above will help you<>

If you are satisfied with me, please give it a thumbs up<>

Your praise is the infinite motivation for me to answer the question <>

Hello. Hello, it is normal for the diesel engine to make a loud noise, because when the diesel engine starts cold, the sound of the engine will be slightly louder than when the car is hot, as long as the sound sounds even, the lack of slippery softness, not harsh, no problem Oh, I hope the above will help you<>

If you are satisfied with me, please give it a thumbs up<>

Your praise is the infinite motivation for me to answer the question [you know how to make silver].

I ran normally and turned off the fire.

The refueling machine refueling old sound is how to get back to the defeat Hello search for the front relatives, the general situation is that the oil gun is not put well. If you put the gun back to its original position after refueling, it won't sound, and if you don't put the gun back in place after refueling, it will ring non-stop, such as the gun is not in the groove when it goes out or in. The oil gun has a trigger device, if the oil volume reaches the fuel tank sensing device, it will automatically jump the gun to cut off the oil.

Conventional fuel dispensers are used with this kind of self-sealing oil gun, which is designed with an air intake nozzle, and people who do not know think that this air inlet is used to steal oil and absorb oil and gas. In fact, the air intake nozzle of this self-sealing oil gun is connected to the self-sealing mechanism, and the air intake nozzle is equivalent to the switch of the oil gun, once the oil (or the foam from the oil flooding) floods the intake pipe, the self-sealing device will close the oil gun to stop the oil supply. Hope it helps.

Dear Glad for your question The reason for diesel, inferior diesel or not replacing diesel for a long time, etc., are easy to lead to increased friction between the valve and the duct and the hydraulic tappet, etc., so that all kinds of sounds in the engine are abnormal. Bi Fu raided to check whether the water tank was full, and checked whether the antifreeze was full in the winter repentance season; whether the oil is at the specified oil level; Whether the diesel tank has sufficient diesel.

The sound is not too loud: it is usually the sound of the valve or the fuel injector. The sound is even and soft:

Generally fine. Causes of engine oil: inferior oil or not changing oil for a long time, lack of oil, etc.

Abnormal valve noise: Because the oil pressure has not gone up at this time, the valve has not been lubricated in place, and it will be fine after a while.
