Problems solved by technology

[0003] The working environment of the automotive diesel engine controller is relatively harsh, and it also needs to dissipate heat when it is working. In addition, there are requirements for shock absorption, insulation, sealing, waterproof, EMC and EMI, which make the design of the controller more complicated.
Some companies at home and abroad have developed diesel engine controllers, typ

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the drawings.

[0026] Such as Figure 1~3 As shown, an automobile diesel engine controller includes an upper cover plate 1, a lower cover plate 2 fixed to each other, and a control circuit board fixed in a cavity formed by the upper and lower cover plates. The upper cover plate 1 is The atmospheric pressure sensing device 3 and at least one connector 4 are fixed, the four corners of the upper cover plate 1 are provided with mounting holes, and the connector 4 includes a cylindrical socket and a socket fixed in the socket. The stitches pass through the upper cover plate and are welded and fixed to the control circuit board. The characteristic is that the upper cover plate 1 is provided with a boss 5 for protecting the atmospheric pressure sensing device, and the boss 5 A channel groove 6 is provided on one side of the, the atmospheric pressure sensing device 3 is fixed in the groove 6, and the end surf...

Abstract

The invention relates to a car diesel engine controller which comprises an upper cover plate and a lower cover plate that are fixed with each other, and a control circuit board fixed in a cavity consisting of the upper cover plate and the lower cover plate, wherein the upper cover plate is fixed with an atmospheric pressure inducing device and at least one socket connector, four corners of the upper cover plate are all provided with mounting holes, the socket connector comprises a column socket and a pin fixed in the socket, the pin passes through the upper cover plate and is welded and fixed on the control circuit board, the upper cover plate is provided with a lug boss used for protecting the atmospheric pressure inducing device, one side of the lug boss is provided with a channel groove, the atmospheric pressure inducing device is fixed into the groove, and the end face of the upper cover plate is provided with a radiating structure. Compared with the prior art, the invention has the characteristics of light weight, small volume, better radiation, better insulation and shock absorption, and the like.

Description

Technical field [0001] The invention relates to an automobile diesel engine controller, in particular to an automobile diesel engine controller which can make an electronically controlled diesel engine operate reliably and safely. Background technique [0002] With the global energy crisis and environmental pollution becoming more and more serious, only the use of electronic control systems for diesel engines can meet the increasing requirements of countries around the world for automobile energy conservation and emissions. The controller is the "core" of the entire electronic control system. It receives signals from various sensors and switches to detect the running status of diesel engines and automobiles in real time, and then judges and outputs appropriate control commands through pre-stored programs in the controller to determine the execution How to operate the engine to ensure that the diesel engine and the car run safely according to the driver’s intentions. [0003] The ...
