What to do if the engine noise is loud.
Solutions to loud engine noise are as follows:
1. Loud engine noise is related to. unsuitable or dirty engine oil. Change the engine oil.
2. Check the bearings of the generator, compressor, idler pulley and tensioner for damage. If the bearing is damaged, it will make a loud noise. /p>
3. You can do it. The machine cover and firewall are equipped with sound-absorbing cotton. An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (petrol engines, etc.), external combustion engines (Stirling engines, steam engines, etc.) , electric motors, etc. generally converts chemical energy into mechanical energy.
4. The motor is applicable to both the power generation device and the whole machine, including the power device (such as a wordgasoline engine, an aviation engine). The engine originated in England, so the concept of engine also comes from English. Its original meaning refers to the mechanical device that generates energy.
The reasons for loud engine noise and solutions are as follows:
1. Poor oil quality. If you use poor quality fuel, the combustion conditions in the engine will deteriorate, causing violent vibrations and noise.
Solution: In this case, generally replacing the fuel with better quality can reduce engine noise
2. The motor is poorly secured. You should know that the motor is not just placed. in the engine compartment, but rely on parts such as machine dog pads for support and attachment. If these parts are old and loose, the motor will make noise during operation.
Solution: In this case, it is necessary to checktake care of the engine support and fixed parts. Usually you just need to tighten or adjust them.
3. The engine noise is loud. during a cold start. When the car starts after being parked for a long time, the engine vibrates violently and then makes a “popping” noise.
In fact, after prolonged parking of the car, practically all the lubricating oil flows into the engine oil pan. When the car is cold, the oil pump cannot immediately increase the oil pressure, esp. the valve inside the cylinder head. There is not enough lubrication when starting the car and the hydraulic lifter and mechanical rocker arm are not working properly, causing the noise.
There are two basic reasons. for loud engine noise: 1. Engine valve When there is too much carbon deposits or the timing setting is incorrect, the engine will make a “pop, pop, pop” sound.At this time, it is necessary to clean the carbon deposits. on the valves and adjust the valve timing. 2. Improper use of engine oil or dirty engine oil will cause friction and noise during engine operation. In such a situation, the engine oil needs to be replaced. 3. When the motor belt is not tensioned enough, the motor will produce a high-pitched squealing sound during operation. In this case, the motor belt must be adjusted. 4. When the intake and exhaust pipes leak, when starting the engine, gas will escape from the leak point, causing vibration and noise. In this case, you need to check the intake and exhaust pipes, replace it quickly. 5. When using poor quality fuel, the combustion conditions in the engine will worsen, resulting in noise. Faced with this situation, replace the fuel with a better fuel.eur quality and with higher label can avoid noise.
