Supply method and system for intelligent control of gasoline engine fuel oil

Abstract

The present invention relates to a method and system for controlling intelligently fuel supply by gasoline engine. The fuel system comprises an oil pump, an injection guide, a pressure reflux valve, a gasoline tank, a check valve and an oil supply and return pipeline. Wherein, a pressure sensor and an intelligence controller, a transmitting bus, a sound and light alarm circuit are increased. After calculating and judging of control software of microprocessor of intelligence controller, outputs a certain pressure to the oil pump engine, at the same time, the microprocessor detects pressure signal of pressure sensor amends voltage transmitted to the oil pump motor at any moment according to the pressure signal to remain stabilization of system pressure, and detecting, judging problems resisted in fuel supply system to give off sound and light alarm in time. The present invention saves energy, reduces consume, can detect fuel supply system intelligently and determine faults and alarm, enhances the initiative safety of vehicle on moving.

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.
