The invention relates to the technical field of diesel engines, and discloses an electronic control oil injector system. The electronic control oil injector system comprises an oil injector body, an electromagnetic valve and a transmission device which is horizontally arranged on the oil injector body, wherein the transmission device comprises a shell and a transmission assembly, an oil passage isarranged in the shell, the shell is connected with an oil supply pipeline, the oil passage correspondingly communicates with the oil supply pipeline and a fuel oil path of the oil injector body, andopening and closing of the electromagnetic valve controls the transmission assembly to selectively enable the oil supply pipeline to communicate with or separated from the fuel oil path. According tothe provided electronic control oil injector system, the transmission assembly is horizontally arranged on the oil injector body, so that the phenomenon that the opening degree of the transmission assembly is not consistent due to the fact that oil supplementation and leakage are different is effectively avoided, the execution efficiency of controlling the transmission assembly by the electromagnetic valve is improved, the service life of the electronic control oil injector system is prolonged, moreover, the machining and assembling difficulty is reduced, and the machining and manufacturing cost is reduced.
Description
technical field [0001] The invention relates to the technical field of diesel engines, in particular to an electronically controlled fuel injector system. Background technique [0002] The fuel injector of marine low-speed diesel engine and its control drive system are one of the core components of the diesel engine, and its drive characteristics will directly affect the economy and emission of the engine. At present, the electro-hydraulic drive control systems for injectors widely used in the market are based on the principle of indirect drive, that is, the pressurized chamber of the actuator unit is filled with servo oil in the form of high pressure or low pressure through the orifice or one-way valve, When the fuel inlet pipe needs to be opened, the control unit sends an instruction to control the solenoid valve to be energized, and the high-pressure servo oil drives the booster piston to move upward, compressing the servo oil in the booster chamber, and the compressed hi...
