Electronic-control fuel jetting system of engine

The invention relates to an electronic-control fuel jetting system of engine of a single-cylinder wind-cooling diesel engine. The system comprises an electric oil transporting pump, an oil transporting tube, an electronic-control oil jetting pump, a high-pressure oil tube, an electronic-control oil jetting device, an oil inlet metering valve and an electronic control unit, wherein the oil inlet metering valve is installed on the electronic-control oil jetting pump and is used for adjusting the oil pressure of an oil storing cavity of the electronic-control oil jetting pump, the output end of the electric oil transporting pump is connected to the inlet end of the electronic-control oil jetting pump through the oil transporting tube, the outlet end of the electronic-control oil jetting pump is connected to the inlet end of the electronic-control oil jetting device through the high-pressure oil tube, the electronic control unit is connected to the oil inlet metering valve through an electronic-control circuit, and the electronic control unit is connected to the electric oil transporting pump through the electronic-control circuit. The electronic-control oil jetting device can jet the fuel under the high pressure of the pump end, and the system is economical, capable of reducing the discharging quantity, automatic in control and high in reliability.
