Intelligent controller for gasoline engine fuel injection pump

Abstract

The present invention relates to an intelligence controller of fuel pump of gasoline engine, which comprises a steady voltage circuit, an overcurrent protector, a driving circuit, an oil pump motor, amicroprocessor and an input signal circuit. The input signal circuit inputs pressure signal of pressure sensor and control signal of engine electronic control cell ECU, the input signal circuit is connected with microprocessor which is connected and control the driving circuit by output port; the driving circuit connects or drives oil pump motor, according to fuel pressure in oil supply system inspected in real time, the control software of microprocessor processes data, controls rotate speed of oil pump, makes the oil pump supplying different fuel and remaining stable fuel pressure needed byfuel supply loop, and gives off sound and light alarm signal when the judging and supplying fuel supply system has matters. The present invention reduces energy consume and abrasion of oil pump, enhances initiative safety of vehicle on moving.

Description

technical field [0001] The invention belongs to a gasoline engine oil supply system, in particular to an intelligent controller of a gasoline engine fuel pump. Background technique [0002] Automobiles are entering our society and families at a rapid rate. Car performance, fuel consumption, etc., are more and more people's attention. People are working hard from all aspects to carry out research on energy saving, pollution reduction and environmental protection of automobiles. Through our careful analysis and research, the automobile oil pump is also one of the equipment that consumes the most fuel and cannot be ignored. [0003] At present, with the development of automobile technology, almost all gasoline-fueled vehicles use EFI fuel supply technology, and one of the most basic requirements of EFI technology is to provide a certain fuel pressure at the front end of the fuel injector. In the early stage of the application of EFI technology, a mechanical pressure regulati...

Problems solved by technology

In this way, a large amount of fuel is pumped by the oil pump, and after a turn, it returns to the fuel tank, causing the oil pump to do a lot of useless work and consume a lot of energy.

Moreover, since the oil pump has been running at high speed, it also accelerates the wear of the oil pump and reduces the service life of the oil pump.
