What Causes the Car Throttle to Fail to Accelerate?

[StAlaina]

The reasons why a car's throttle fails to accelerate are: 1. Clogged fuel line; 2. Blocked exhaust system; 3. Excessive carbon buildup in the throttle body. The functions of the throttle are: 1. Controlling the engine speed by adjusting the pedal pressure; 2. The throttle regulates the carburetor to determine the engine's output power. The working principle of the throttle is: When the accelerator pedal is pressed, it directly controls the throttle body, increasing the throttle opening, which allows more air to enter the engine. At this point, the ECU commands the fuel injection system to inject more fuel, thereby increasing the engine speed and enabling the car to accelerate. Solutions for abnormal noises when accelerating include: 1. Changing the engine oil; 2. Cleaning carbon deposits from the engine; 3. Replacing spark plugs; 4. Conducting a comprehensive inspection and repair of the vehicle.
