What should I do if there is a current noise in the car engine?

Introduction What should I do if there is a running noise in the car engine? Because when the motor is turned on, there will be current flowing through it and the motor will resonate, so there will be a current sound. Car engines are supplied for cars

What should I do if there is a current noise in the car engine?

As there is current flowing through the motor when it is turned on, the motor will resonate, so there is current noise.

The car engine is a device that provides power to the car. It constitutes the heart of the car and determines the power, economy, stability and environmental protection of the car. According to different energy sources, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle engines and hybrid engines.

Common gasoline engines and diesel engines are reciprocating piston internal combustion engines, which convert the chemical energy of the fuel into the mechanical energy of the piston movement and power output to the outside. The gasoline engine has high speed, low mass, low noise, easy starting and low manufacturing cost; the diesel engine has a high compression ratio, high thermal efficiency andbetter economic performance and better emissions performance than gasoline engine.

Detailed information:

When the engine is running, the high pressure in the combustion room is not burned. Gases, acid, moisture, sulfur and nitrogen oxides enter the crankcase through the gap between the piston ring and the cylinder wall and mix with the metal powder produced by wear of the piston rings. parts to form mud.

When the quantity is small, it is suspended in the oil. When the quantity is large, it precipitates oil, blocking the filter and oil holes, causing difficulty in lubricating the engine and causing wear. In addition, when engine oil oxidizes at high temperatures, it will form paint film and carbon deposits that adhere to the piston, which will increase engine fuel consumption andwill reduce its power. In severe cases, the piston rings will bind and seize. the cylinder will be fired.

Therefore, use BGl05 (effective and fast cleaning agent for the lubrication system) regularly to clean the crankcase and keep the inside of the engine clean.

Hello, regarding this problem, if the vehicle makes an abnormal noise when starting from cold, the carbon brush inside the starter may be defective.

The working principle of the starter is that after the electromagnet is energized, the electromagnet works to combine the starter gear with the motor flywheel and rotate at the same time. The engine can be started. Once the engine starts, the speed will return quickly. This fault is caused by the starter gear not returning quickly, causing abnormal noise caused by the flywheel gear, so the starter motor should be checked.

Detailed information:

The timing belt is a rubber component. As engine running time increases, the timing belt and. timing belt Timing belt accessories, such as timing belt tensioners, timing belt tensioners and water pumps, etc., wear out or age.

Therefore, the manufacturer of any engine equipped with a timing belt will have strict requirements to replace the timing belt and accessories regularly within a specified time frame. The replacement period will generally vary depending on the engine structure. must be replaced when the vehicle has traveled 60,000 to 100,000 kilometers.

The specific replacement cycle should be based on the vehicle service manual. The timing belt is generally considered replaced at 80,000 kilometers. MEven if you have a timing belt in your car, if it breaks, you won't be able to replace it. Therefore, when the total driving distance reaches 80,000, it is recommended to consider replacing it. The timing belt is located behind the radiator fan.

Hope this helps, thanks!
