Cars are an indispensable means of transportation in our daily lives, but with the increase of time of use, we may find that the engine of the car is getting louder and louder, and sometimes even abnormal noise. What's going on? How should we deal with it? To answer these questions, we interviewed an auto mechanic with years of experience, who told us about some common causes and solutions.
First of all, one possible reason why the engine is louder is that the engine lacks oil. The engine is the heart of the car, and it needs plenty of lubricating oil to keep it running. If the engine oil supply is insufficient, or the oil quality is not good, it will cause friction inside the engine to increase, resulting in more noise. Therefore, we should regularly check the oil level and oil quality of the engine oil, and if we find that the oil quantity is insufficient or the oil quality is worse, we should replace or add the engine oil in time.
Secondly, another possible reason for the engine to become louder is the carbon deposit in the engine. In the process of burning gasoline in the engine, some incompletely burned carbon particles will be produced, and these carbon particles will adhere to the valves, pistons, spark plugs and other parts of the engine, forming a layer of black deposits, called carbon deposits. Carbon deposits can affect the airtightness and compression ratio of the engine, reduce the performance and efficiency of the engine, increase fuel consumption and emissions, and also increase the noise of the engine. Therefore, we should regularly clean the carbon deposits of the engine, which can be cleaned by some professional cleaning agents or by going to a repair shop.
Finally, there is also a possible reason why the engine is louder because some parts of the engine are damaged or loose. The engine is a complex machine composed of many parts, and if some of the parts are worn, broken, deformed, loose, etc., it will lead to unbalanced operation of the engine, resulting in abnormal vibration and noise. For example, such problems can occur in engine belts, chains, bearings, valves, piston rings and other components. Therefore, we should regularly check the condition of each component of the engine, and if we find any damaged or loose parts, we should replace or tighten them in time.
In conclusion, louder engines are a relatively common problem, and it can have a variety of causes and solutions. As car owners, we should pay attention to observing and listening to the sound of the engine, find and deal with problems in time, keep the engine in good condition, prolong the life of the engine, and improve the safety and comfort of the car.
