As for others, it may be internal problems of the engine, such as EGR valve blockage. 3. The engine has a hissing sound, just like steam or air coming out of the engine. Generally, after hearing this sound, the engine will quickly lose power. There may be a problem. The engine is overheated. Check the cooling system.
Oil: such asIf the oil of the vehicle is too viscous, it is easy to cause problems with the engine operation, and the lubrication effect will deteriorate, resulting in loud engine noise. Therefore, at this time, you should go to the repair shop in time to check whether it is time to change the oil, or calculate by yourself whether the maintenance time has come.
The sudden increase in engine sound is closely related to engine oil. Because the initial oil of the new car usually has low viscosity and good heat dissipation, and a little abrasive to help the parts run together, the lubricity is stronger and the natural sound is lower.
The reasons for the louder engine sound are: less oil or the oil is not hot when the car is cold, and the oil pressure is insufficient. There are too many impurities or dirt in the oil, which makes it impossible to effectively adjust the oil pressure.The engine has mechanical interference and the lubricating oil road is blocked.
The reasons are as follows: it is not lubricated enough when the cold car starts, and the hydraulic column and mechanical rocker arm fail to work properly, resulting in a rattling sound. The condition of the oil is not right: if the viscosity of the oil is too high or too low, the engine will make noise. The belt is not elastic enough: the engine makes a squeaky sound at work.
Analysis of the specific reasons for the loud engine noise: 1. Step on the accelerator and find that the acceleration is not obvious, lacks power, and the engine has a hysterical sound. The most likely time to happen is when the engine is hot, or cold, or when there is a shortage of oil.
There is also a relatively unpleasant sound of the engine. The most likely reason may be that the engine is too hot or too cold, and the most likely reason is that there is less oil.Other reasons are relatively complicated, such as the ignition line of the source, or the oil filter of the oil part, etc.
Abnormal sound of the engine compartment. Some of the sound of the engine vibration is a normal phenomenon, but there are also special circumstances, such as the shrilling sound of the belt, which is generally caused by the slippage of the belt; for example, the sharp sound of dry friction of metal parts, which is generally damage to the bearings of generators, pumps and steering booster pumps. The reason.
The reasons are as follows: not enough lubrication when the cold car starts, and the hydraulic column and mechanical rocker arm fail to work normally The work led to the rattling sound. The condition of the oil is not right: if the viscosity of the oil is too high or too low, the engine will make noise. The belt is not elastic enough: the engine makes a squeaky sound at work.
Engine cylinder shortage When the engine lacks a cylinder, the car will show problems such as louder engine noise, unstable idle speed, abnormal body shaking and so on. In this case, the condition of the cylinder and the working condition of the spark plug should be checked.
As for the others, it may be internal problems of the engine, such as EGR valve blockage.3. The engine has a hissing sound, just like steam or air coming out of the engine. Generally, after hearing this sound, the engine will quickly lose power. There may be a problem. The engine is overheated. Check the cooling system.
The reason for the loud noise of the car engine: the first reason: the foot glue is aging or loose; the foot glue is the rubber block cushioned between the engine and the frame. Its function is to reduce the vibration and buffering of the engine during work, and to fix the engine.
The reasons for the sudden louder engine noise may be as follows: during driving, acceleration is normal, and ignition may also be normal. Assuming that when driving at a constant speed, the engine speed is too high and it does not seem to increase the speed. The engine made a sling sound.
The sound of car engineReasons for the loud noise: too much carbon accumulation in the engine, poor oil quality or dirty oil, loosening of the lower guard plate screws of the engine; aging of the engine claw pad, and loose plastic parts in the engine compartment.
1. Reasons for the loud noise of the car engine: insufficient oil or aging, piston ring wear, bearing wear, exhaust pipe problem, fan noise. Insufficient oil or aging. Oil plays an important role in lubricating and cooling the engine. If the oil is insufficient or aging, it will cause increased engine friction, resulting in noise.
2. The reasons are as follows: it is not lubricated enough when the cold car starts, and the hydraulic column and mechanical rocker arm do not work properly, resulting in a rattling sound.The condition of the oil is not right: if the viscosity of the oil is too high or too low, the engine will make noise. The belt is not elastic enough: the engine makes a squeaky sound at work.
3. The reasons for the loud noise of the engine are as follows: the oil condition is not right.
4. When the engine is running, if it makes a dull sound similar to a clapping, it may be because there is a problem with the cylinder valve. In this case, if you drive the car very fast, the sound will disappear in the fast run. Therefore, the sound that will disappear once the express car is driven is likely to be due to the problem of the cylinder valve.
5. Analysis of the specific reasons for the loud engine noise: 1. When you step on the accelerator, you will find that the acceleration is not obvious, there is a lack of power, and the engine has a hysterical sound. The most likely time to happen is when the engine is hot, or cold, or when there is a shortage of oil.
6. The engine noise and jitter generally have the following reasons: 1. The foot glue is aging or loose; the engine cylinder is abnormally missing; the cylinder is abnormal; the mixture is too thick; the timing gear noise is abnormal. The foot glue is aging or loose; the foot glue is a rubber block between the engine and the frame.
If the car is driven for a long time, it is inevitable that there will be a large amount of carbon accumulation, which will also cause loud engine noise. When the engine is working, the carbon will be attached to these internal friction parts, which also increases the friction and makes the sound louder. Therefore, you should develop good driving habits and maintain your car in time, so that the engine will not be affected by carbon accumulation.
It may be caused by the sound insulation. If you are outside the car, you can hear the normal operation of the engine, but you obviously feel that the noise is relatively loud after sitting in the car, which means that there is something wrong with the sound insulation effect of the vehicle.
Generally speaking, cars that have been used for a long time will more or less have valve problems, which will lead to louder noise! The combustion chamber shrinks, causing explosion noise. Cars and engines that have been used for a long time accumulate more carbon, especially direct injection engines that have not been cleaned for a long time. A large amount of carbon will inevitably accumulate inside the combustion chamber.
Why does the engine noise become louder after the car has been driven for a long time? The reasons are as follows: the engine fixed shockproof cover will age; the engine fixed shockproof cover will age, and the aging shockproof cover will gradually lose its function, resulting in increased engine vibration, and the vibration will be transmitted to the car body, which will make the steering wheel and even the whole vehicle feel the shock. Trembling, and the noise becomes louder.
Why does the engine sound get louder and louder after driving for a long time? It is normal for the engine to make various sounds during operation. They are inside and outside the engine. For example, when the valve is closed, the valve will collide with the valve seat, the timing chain will rub against the chain guide plate, and the hydraulic valve regulator and valve lever will make noise.
Add the wrong gasoline label, or the gasoline is not qualified. If the car needs No. 97 gasoline, but No. 93 oil is added, which will not only shorten the life of the engine, but also make it easier to accumulate carbon and make the exhaust gas black. At this time, the sound of the car engine made people feel obviously louder. The atomization of the fuel nozzle will also cause abnormal engine noise.
