Do You Need to Keep Pressing the Accelerator While Driving?

[SanRiley]

You do not need to keep pressing the accelerator while driving. The functions of the accelerator are: 1. Controlling the engine speed by adjusting the amount of pedal pressure; 2. The accelerator regulates the carburetor to determine the engine's output power. The working principle of the accelerator is: Pressing the accelerator pedal directly controls the throttle valve, which increases the throttle opening, allowing 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 accelerating the vehicle. Solutions for a sluggish accelerator response include: 1. Checking the gasoline pressure and cleanliness, and replacing the fuel filter; 2. Inspecting the ignition system, cylinder wires, and spark plugs; 3. Checking the cylinder pressure to see if the engine is running with a misfire; 4. Ensuring the intake and exhaust pipelines are unobstructed; 5. Verifying the ignition timing, throttle position sensor, and idle motor; 6. Using higher-quality gasoline.
