Car maintenance is an important measure to keep your car running properly and extend its service life. During the maintenance of the car, some car owners may encounter the problem of the engine becoming louder after maintenance, which makes them confused and worried. So, what is the reason for the loud engine after car maintenance? Let's break it down.
1.Too much oil filling.
Engine oil is the "blood" of the engine and is essential for its protection. However, if the oil is filled too much, it will increase the frictional resistance inside the engine, causing the engine to become louder. Therefore, when maintaining, car owners need to pay attention to the level of the engine oil to ensure that the oil is within the appropriate range.
2.The viscosity of the oil is not suitable.
The viscosity of the oil has a big impact on the sound of the engine. If the viscosity of the oil used does not match the requirements of the engine, it may cause the engine to become louder. For example, if you use an oil with too low viscosity, the engine may "hum" at high speeds; If you use an oil that is too viscous, you may experience a "rustle" sound when the engine is running at low speeds. Therefore, when choosing an engine oil, the owner needs to choose the right viscosity according to the requirements of the vehicle manual.
3.The engine has too much carbon deposit.
Engine carbon deposits refer to the black substance produced inside the engine due to incomplete combustion. Excessive carbon deposits in the engine can lead to unstable engine operation, which in turn causes the engine to become louder. Therefore, during the car maintenance process, car owners need to regularly clean the engine carbon deposits to keep the inside of the engine clean.
4.Wear and tear of parts.
During the driving of the car, the parts and components will wear out. If wear reaches a certain level, it may cause the engine to run unsteadily and become louder. For example, engine bearing wear, crankshaft wear, valve wear, etc., can all cause the engine to become louder. Therefore, during car maintenance, car owners need to regularly check the wear and tear of engine parts and replace parts with serious wear in time.
5.Problems with the layout of the engine compartment.
The layout of the various components in the engine compartment of a car also has an impact on the sound of the engine. If the layout of the components in the engine compartment is not right, it can cause the engine to resonate during operation, which can make the engine louder. Therefore, in the process of car maintenance, car owners need to pay attention to the layout of parts in the engine compartment to ensure that the layout is reasonable.
There can be a variety of reasons why the engine is loud after car maintenance. When car owners encounter this situation, they need to investigate from many aspects, find out the cause and solve it in time to ensure the normal operation of the engine and prolong the service life of the car. At the same time, car owners also need to carry out regular car maintenance to keep the car in good running condition.
