The invention relates to an oil-saving controller of an oil injection nozzle, which comprises a 12V storage battery, an electric switch, a CPU controller, a resistor, a diode, a silicon controlled rectifier, a SH4213 chip and an oil injection nozzle. The oil-saving controller is characterized in that the power line of the SH4213 chip is connected with the electric switch, the signal line of the SH4213 chip is connected with the CPU controller, and the output line of the SH4213 chip is connected with the oil injection nozzle. The 12V storage battery is used for supplying electric energy to theoil-saving controller of the oil injection nozzle. After an engine works, the SH4213 chip compresses the oil injection time given by the CPU controller, shortens the total time for oil injection of each section by 20% and supplies 80% of the oil injection time after processing to the oil injection nozzle for oil injection so as to shorten the oil injection time of the oil injection nozzle, thereby ensuring oil saving and exhaust emission reduction.
Description
technical field [0001] The invention relates to an electronic injection control system of a gasoline engine, in particular to a fuel-saving controller for a fuel injector. Background technique [0002] At present, gasoline engines generally use electronic fuel injection systems, and their working precision is much higher than that of carburetor fuel supply systems. However, as vehicles age, the fuel supply of fuel injectors is significantly higher than that of new cars, resulting in fuel consumption and exhaust pollution. aggravated. Contents of the invention [0003] The object of the present invention is to provide a fuel-saving controller for fuel injectors, which has the function of saving gasoline on the basis of keeping the original system structure unchanged, and can be used as a fuel-saving controller for fuel injectors of gasoline locomotives. [0004] The present invention is realized by the following technical scheme: the fuel-saving controller of the fuel inj...
