Abstract

The invention discloses a plastic throttle body, which comprises a wire drawing swing frame, a plastic casing, a reset spring, a throttle valve sheet, a first tapping screw, a throttle valve shaft, a bearing, a limit clamping board, a long groove, a first hanging leg, a second hanging leg and an installing hole insert piece. The installing hole insert piece is pressed into the plastic casing, the bearing is pressed into the plastic casing, the throttle valve shaft penetrates through the bearing and keeps to be connected with the bearing in rolling mode, the limit clamping board is fastened onto the plastic casing through the first tapping screw, the long groove is arranged on the throttle valve shaft, the throttle valve sheet is arranged in the long groove, one end of the reset spring is hung at the first hanging leg, the other end of the reset spring is hung at the second hanging leg, and the wire drawing swing frame is arranged at one end of the throttle valve shaft. The weight of the plastic throttle body is reduced.

Description

technical field [0001] The invention relates to a throttle body assembly, in particular to a plastic throttle body. Background technique [0002] The throttle body is an important part of the EFI system, which mainly controls the intake air flow and is installed on the intake manifold. One end of the throttle cable is connected to the cable swivel of the throttle body, and the other end is connected to the accelerator pedal. When the engine accelerates, step on the accelerator pedal and pull the cable swivel through the accelerator cable to open the throttle body to the required angle. The throttle position sensor (Throttle PositionSensor, TPS) converts the throttle opening (that is, the engine load) into an electrical signal and then inputs it to the ECU (Electronic Control Unit, electronic control unit). Such as idling conditions, partial load conditions, heavy load conditions, etc., and control the fuel injection time according to the requirements of the mixture concentr...
