Changhe Freda throttle fault

There are three phenomena: short circuit or open circuit of no-load switch; The idle switch is not closed when the throttle valve is fully open, or the idle switch is still closed when the throttle valve has a certain opening; The sliding contact of the linear variable resistor is poor, and the output signal of the throttle position sensor is interrupted intermittently during the process of the throttle valve from fully closed to fully open.

Throttle, also known as "throttle" and "throttle", refers to the control device that controls engine power (thrust). On the piston aero-engine, the throttle valve controls the opening of carburetor to control the filling amount of cylinder, thus determining the output power of the engine. On the gas turbine engine, the throttle valve controls the fuel flow measured by the fuel regulator, thus determining the thrust generated by the engine. The position of the throttle is controlled by the driver operating the throttle lever in the cockpit, and it is transmitted to the carburetor or fuel regulator on the engine through control system components such as pull rod, rocker arm, torsion tube, steel cable, pulley and sector wheel. On an airplane, the throttle lever is always pushed forward to increase the power (thrust) and pulled back to decrease the power (thrust).

The accelerator pedal is also called the accelerator pedal. It is a part of automobile fuel supply system. The engine speed can be controlled by controlling the pedaling amount, engine throttle opening, air intake and oil quantity by computer.
