The invention provides an intelligent spraying system and a spraying method. The system comprises a fuel injection hole cover, a fuel injection hole cover sensor, an ECU, a main fuel tank, a main fuel tank an oil pump, a main fuel tank pressure sensor, an auxiliary fuel tank, an auxiliary fuel tank oil pump, an auxiliary fuel tank pressure sensor, a control electromagnetic valve, a high-pressureoil pump and an oil injector. The method can realize adopting different spraying parameters when spraying different fuels according to different characteristics of the fuels. In the invention, the fuel injection information of a gas station is mainly obtained by a wireless communication mode; during the spraying process, corresponding information is retrieved and the spraying pressure and spraying rule are determined by the ECU; furthermore, the intelligent spraying system supporting the spraying of various fuels is realized by the main oil tank and the auxiliary oil tank, thus meeting the requirement of using various fuels simultaneously in the future.
Description
technical field [0001] The invention belongs to the field of mechatronics mechanical equipment, and relates to an intelligent fuel injection system for completing combustion of different fuels on the same engine. Background technique [0002] Smart Engine (Smart Engine) is a concept proposed by the academic circles for the application of alternative energy in engines, that is, different fuels are used to burn on the same engine to promote the development of alternative energy. This idea is only conceptually proposed by a small number of scientists, and its functions have not yet formed a specific, complete, and unified description. The smart fuel injection system is one of the core functional components of the Smart Engine. At present, domestic and foreign research on this aspect still stays in the blending of two fuels without changing the original injection device on the engine. For example, the use of mixed fuels of gasoline and ethanol gasoline on gasoline engines, or t...
