Integration unit of air control shutter and controller and method for manufacturing same

Abstract

The invention discloses an air throttle and controller integrated unit, comprising an air throttle body; the air throttle body is connected with a controller which is internally provided with a controller internal air current channel, the controller internal air current channel is in abutting joint with an air current channel at the side of the air throttle body and the joint is provided with a sealing element; the controller is integrated with an intake pressure sensor, an intake temperature sensor and an electronic circuit board. The air throttle and controller integrated unit has the advantage that: the invention can provide the structure with completely common use and low cost switch for transforming a carburetor of a small-scale engine into an electronic fuel injection system. Meanwhile, with the air throttle and controller integrated unit, wiring harness connection among electrical components can be simplified, thus reducing the cost of the system and improving reliability, maintainability and installing flexibility of the system; furthermore, the main problem of heat load in the air throttle and controller integrated unit is fully taken into account, and the heat load of the electrical components can be greatly reduced by adopting the structures of reducing the contact area with a heat source, keeping away from the heat source, improving the heat dissipation performance of the electrical components, and so on.

Description

technical field [0001] The invention relates to an integrated unit of a throttle valve and a controller used in the electronic field of automobiles and motorcycles and a manufacturing method thereof. Background technique [0002] In the field of automotive electronics, in the traditional electronic fuel injection system, the sensors are arranged in a distributed manner, but with the improvement of system integration and the increase in the cost of connectors, especially small engines are undergoing the conversion from carburetors to electronic fuel injection systems The process puts forward higher requirements for the arrangement of the electronic fuel injection system on the whole vehicle, such as having universality, minimizing the volume, and minimizing the number of connectors used. Therefore, an integrated unit of the throttle valve and the controller has appeared, such as described in the patent with the publication number CN1751174. The throttle body is provided with ...

AI Technical Summary

Problems solved by technology

Especially under the action of heat conduction, the heat of the engine will soon be transferred to the throttle body, making the throttle body itself a heat source, at this time the cooling effect of the airflow movement in the internal channel of the throttle body is very small
