What are the reasons why the car throttle cannot be increased?

The reasons why the car throttle cannot be increased are: 1. Fuel line blockage; 2. Exhaust system blockage; 3. Excessive carbon buildup in the throttle. The throttle, also known as the air valve or throttle valve, refers to the control device that regulates engine power. The throttle position is manipulated by the driver in the cockpit via the throttle lever, transmitted through control system components such as rods, rocker arms, torque tubes, cables, pulleys, and sector gears to the carburetor or fuel regulator on the engine. The car's throttle pedal does not directly control the fuel injection volume but rather the throttle opening. When the throttle pedal is pressed, the throttle opening increases, allowing more air to enter the engine, which in turn prompts the fuel injection system to inject more fuel.
As a regular driver, I get anxious when the throttle doesn't respond. The most common issue is a problem with the fuel system, such as a malfunctioning fuel pump not delivering enough fuel or a clogged fuel filter preventing the engine from getting sufficient fuel. Air supply is also crucial; a dirty air filter filled with dust can restrict airflow, making the engine feel weak. Ignition system issues like worn spark plugs or faulty ignition coils can also cause misfires, leading to poor acceleration. Additionally, a faulty throttle position sensor or electronic control module can affect the computer's ability to precisely control speed. In such cases, don't push it—head to a repair shop immediately for inspection and part replacement to avoid accidents, especially at high speeds. Regular maintenance can significantly reduce these frustrations.
