Problems solved by technology

Because a set of motor is used to control the intake air at idle speed, its mechanical structure is too complicated, and the electronic control system is complicated, and the motor is used to control the intake air volume at idle speed through gear transmission, which has great influence on the machining accuracy of the gear and the transmission accuracy of the gear (installation Accuracy) requirements are quite high, therefore, the existing mechanical processing and installation levels are difficult to meet the application requirements of precisely controlling the intake air volume of the engine

Embodiment Construction

[0015] figure 1 figure 2 As shown, the throttle valve plate 3 is fixed on the throttle shaft 2 and arranged on the air intake passage of the throttle body 1; the throttle shaft 2 is installed on the throttle body via the bearing 9. The microcomputer control device of the present invention is composed of a single chip (Installed in the engine control system), the motor drive circuit cascaded with the single-chip microcomputer is installed in the engine control system together with the single-chip microcomputer, the accelerator pedal position sensor (installed near the accelerator pedal in the cab), the throttle position sensor 10 (installed in the section The housing 12 of the valve body) and other components. The single-chip microcomputer receives the throttle opening signal, the throttle opening signal and the engine operating condition signal for processing, and outputs the motor control signal, and finally drives the DC motor 4 (installed on the throttle body) through a two...

Abstract

This is about a kind of electronic door of saving gas, which belongs to the system of saving air in the engine in the car. It includes the saving gas body, valve chip of saving air, the axis of saving air, DC engine, gear structure for decreasing speed, location sensor and spring, one of whose side is fixed on the body of saving gas, the other side is fixed on the axis of saving gas door. there is also the structure of changing speed. The outside bolt is fixed on the body of saving gas and the inside one on the inside of changing bolt. The spring is fixed between them. In the invention the position is capable to change. The amount of inside gas can be controlled accurately in the low speed, and at the same time it cuts the precision of the production.

Description

1. Technical Field [0001] The invention relates to an automobile engine air intake system component, in particular to the technical field of a throttle assembly used in an automobile internal combustion engine air intake system. 2. Background technology [0002] There are two types of throttle bodies used in automobile internal combustion engine systems: mechanical throttle bodies and electronic throttle bodies. In the current mechanical throttle body, the throttle shaft is connected to the accelerator pedal in the cab through a wire rope and a lever. The driver controls the opening of the throttle by stepping on the accelerator pedal and turning the throttle shaft, thereby changing the area of ​​the intake passage at the throttle, adjusting the intake volume of the engine, and achieving the purpose of changing the output power of the engine. For special conditions, additional devices are used for air or fuel compensation, and solenoid valves or stepper motors are used to drive t...
