There are two basic reasons for loud engine noise: 1. When there is too much carbon deposits on the engine valve or the timing adjustment is incorrect, the engine will make a "puff, puff, puff.” , the carbon deposit from the valves must be cleaned. Just 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 should check the intake and exhaust pipes and replace them in time. 5. Whenthe use of poor quality fuel, the combustion conditions in the engine will worsen, resulting in noise. Faced with this situation, replacing the fuel with better quality fuel with a higher label can avoid the noise.
What to do if the motor is noisy
Both have their own advantages and disadvantages, and we cannot simply say which is safer.
The advantages of gasoline generators are: small size and easy to move. Less noise and fewer emissions. The disadvantages include: high fuel consumption and short continuous working time.
Benefits of kerosene generators include: Multi-faceted system protection, such as overload, overcurrent, overvoltage, etc. Suitable for high power applications such as industry, hospitals, hotels, etc. Disadvantages include: louder noise and more emissions.
What to do if the engine noise is loud.
Solutions to loud engine noise are as follows:
1. The noisy engine. the noise is caused by unsuitable or excessive engine oil. If it is dirty, change the oil.
2. Check the generator, compressor, idler and tensioner bearings for damage. , they will make a loud noise
3. The machine cover can be made and the firewall can be installed 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, includingincluding the power device (such as gasoline engine, 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 fuel can reduce engine noise
2. The engine is loose. The engine is not simply placed in the engine compartment, but is supported and secured by parts such as claw pads. If these parts are old and loose, the motor will make noise during operation.
Solution: In this case, it is necessaryPlease check the engine mount 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 starts cold, the oil pump cannot immediately increase the oil pressure. especially the valve inside the cylinder head. There was not enough lubrication when starting the car, and the hydraulic lifter and mechanical rocker arm did not work properly, causing noise
