FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: proposed diesel engine starting device contains internal combustion chamber, system building preliminary compression for ignition of fuel, fuel pump and mechanism transmitting motion to working member. System building preliminary compression is made in form of cylinder arranged over internal combustion chamber and containing starting chamber with liquid in upper part of cylinder and connected with reservoir filled with liquid. Electrodes are driven into starting chamber which are connected with high-voltage pulse source. Starting chamber is separated from cylinder space by separating piston. Separating piston of starting chamber and compression piston are rigidly interconnected. Compression spring is installed between upper surface of compression chamber cover and movable piston of starting chamber. Mechanism transmitting motion of working member contains crank-and-connecting rod member and pneumatic spring in form of cylinder with chambers divided by piston. Piston of pneumatic spring is provided with rod hinge-connected with connecting rod neck of crank-and-connecting rod member. Cylinder of pneumatic spring is hinge-connected with stationary part of engine. Chamber of cylinder of pneumatic spring are provided with air pockets. High-voltage pulse source is connected with detonation pickup installed on combustion chamber and differential diaphragm pressure pickup connected by tubes with air pockets.
EFFECT: improved reliability and safety of starting system of internal combustion engine, increased service life, enlarged sphere of application of engine.
