Abstract

The invention discloses an engine electronic throttle, comprising a throttle body, a throttle shaft arranged on the throttle body, a cover plate and a printed circuit board assembly arranged on the cover plate, the printed circuit board The assembly is arranged opposite to the end face of the throttle valve shaft, wherein a shielding cover for accommodating the printed circuit board assembly is arranged between the printed circuit board assembly and the cover plate, and the shielding cover has a base plate part connected with the cover plate and located on the The side wall portion outside the printed circuit board, on which the printed circuit board is fixed. The invention can ideally shield external electromagnetic interference, has high control precision, and its limit structure is simple, novel and compact. The torsion spring is firmly installed on the sector gear with small impact, and can realize good limit of the throttle valve.

Description

technical field [0001] The invention relates to an engine electronic injection system, in particular to an engine electronic throttle. Background technique [0002] The electronic throttle is an important control part of the automobile engine. Its function is to provide continuously variable air flow to the engine, to control the normal operation of the engine by increasing or decreasing the air flow, and to provide the car with the power required under various working conditions to achieve reasonable The air-fuel ratio can fully burn the mixed gas, reduce emissions, and improve engine power, economy, and comfort. [0003] The engine transmits the throttle opening signal through the throttle shaft installed on the throttle and the Hall element opposite to the throttle shaft, and the ECU then comprehensively judges based on the acquired throttle opening signal and accelerator pedal signal to obtain the best In this process, the external magnetic field is likely to interfere ...
