DEVICE FOR STARTING INTERNAL COMBUSTION ENGINE Russian patent published in 2016 - IPC F02N7/00 

FIELD: engines.

SUBSTANCE: device for starting internal combustion engine, comprising a hydraulic accumulator, hydraulic starter with pressure and drain pipelines, on shaft of which there is a freewheel clutch, kinematically coupled with engine crankshaft, working fluid vessel and piston hydraulic pump, inlet pipe of which is connected to working fluid vessel, and outlet - to hydraulic accumulator connected with pressure pipeline of hydraulic starter, mounted on crankcase, to which are connected drain pipeline of hydraulic starter and inlet branch pipe of piston of hydraulic pump. For kinematic connection with engine crankshaft on housing of hydraulic starter is mounted a hydraulic cylinder, connected on one side with underwater pipeline, on other side with a connecting pipeline of hydraulic starter. For connection of hydraulic cylinder between pressure and underwater pipelines there is an electromagnetic valve, connected with electronic control unit, which through a relay and an ignition lock is connected to a storage battery. For measuring frequency of rotation on crankcase is mounted a rotational frequency sensor, connected with electronic control unit. For liquid supply under pressure from vessel with working fluid into hydraulic accumulator and pressure pipeline there is a hydraulic pump. For connection of hydraulic pump and hydraulic accumulator to pressure pipeline there is an electromagnetic valve, connected with electronic control unit. For measurement of pressure between piston hydraulic pump and hydraulic accumulator there is a pressure sensor, connected with electronic control unit.

EFFECT: higher efficiency of starting engine due to automation of operation and control process.
