Intelligent controlled fuel oil supply system of gasoline engine

Abstract

The invention relates to an intelligent controlled fuel oil supply system of a gasoline engine. The fuel oil system consists of an oil pump, an oil spray guide rail, a pressure reflux valve, an oil tank, a one-way valve, an oil supply pipeline and an oil return pipeline. The fuel oil system is characterized in that: a pressure sensor, an intelligent controller, a bus and an alarm circuit are increased; a certain voltage is output to a motor of the oil pump after calculation and judgment by control software of a microprocessor of the intelligent controller, and meanwhile the microprocessor detects a pressure signal on the pressure sensor and modifies the voltage value transmitted to the motor of the oil pump at any time according to the pressure signal to keep the pressure of the system stable; and the microprocessor detects and judges the problem of the fuel oil supply system and gives an audible and visual alarm signal in time. The system has the advantages of energy conservation, consumption reduction, intelligent detection of the fuel oil supply system, fault judgment and alarm function, improvement of running active safety of a vehicle and the like.

Description

technical field [0001] The invention belongs to a gasoline engine fuel supply system, in particular to a gasoline engine intelligent control fuel supply method and system. 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. Due to the early application of EFI technology, a mechanical pressure regul...

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.
