What's the matter with the Han Teng x5 throttle not added?

There are many reasons, such as low fuel pressure or gas in the oil circuit, poor signal of the air flowmeter in the circuit, poor signal of the throttle position sensor, damaged ignition coil, too late ignition time, too large or too small spark plug gap, which will all lead to the car stepping on the accelerator without refueling. 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).
