There is an abnormal sound (click) when the car starts or accelerates while driving.

The abnormal noise made when refueling and speeding up may also be caused by engine oil, either because the engine oil has not been changed for too long, or because the quality or model of the engine oil is not up to standard, or because of oil leakage. Engine oil plays the role of lubricating and cooling the engine. The engine is the heart of a car, and the oil is blood.

At first, the oil temperature of the automobile has not reached the normal value, which leads to the viscosity not suitable for the normal working value of the hydraulic tappet, and the sealing performance of the hydraulic tappet is reduced, so it will make a sound. Throttle, a device for controlling fuel supply on internal combustion engine, is generally controlled by pedal, also called accelerator pedal, which is a device for controlling fuel supply of automobile engine.

Attention should be paid to starting the engine.

Don't step on the accelerator pedal to the end, just a little higher than the idle accelerator. When starting, it is best to refuel just before the clutch linkage point, and the throttle opening should be medium or small. Loosening the clutch should be closely coordinated with stepping on the accelerator, and the action should be agile.

When operating, increase or decrease the throttle according to the road conditions and actual needs. The selected gear should be suitable, so that the engine can run at medium speed and large throttle most of the time to save fuel. When shifting gears, the coordination of refueling, stepping on the clutch and stepping on the accelerator should be coordinated.
