DIESEL ENGINE Russian patent published in 2007 - IPC F02B75/32 F02B75/18 F02F1/42 

FIELD: mechanical engineering; diesel engines.

SUBSTANCE: proposed diesel engine contains cylinder block, cylinder covers bolted to cylinder block, connecting rod-and-crank mechanism, valve-timing mechanism, high-pressure pump, auxiliaries drive and lubrication, fuel, cooling and starting systems. Double-acting cylinders are used in engine. Each cylinder is provided with outlet branch pipes from one side in upper and lower parts which are connected through valves of valve timing mechanism with exhaust manifold and through exhaust fan with atmosphere. Inlet branch pipes are made at other side in upper and lower part of each double-acting cylinder. Fitted inside double-acting cylinders are pistons with seals which are connected with crankshaft through connecting rod and piston rod connected with connecting rod. Combustion chamber separated from double-acting cylinders, two chambers per cylinder, are of similar design, being made in form of hollow vessel designed for high pressure. Each combustion chamber has cooling jacket, inlet and outlet branch pipes, outlet branch pipe of one combustion chamber being connected through valve of valve-timing mechanism with upper inlet branch pipe of double-acting cylinder. Outlet branch pipe of other combustion chamber is connected with lower inlet branch pipe of the same double-acting cylinder. Each combustion chamber has nozzle connected by pipeline with high-pressure pump which is kinematically coupled with crankshaft, glow plug being essentially a spiral wound on insulation base and heated by electric current, and inlet scavenging valve communicating with atmosphere through air filter. Cylinder-receiver is furnished with inlet and outlet branch pipes, the latter being connected with inlet branch pipes of each combustion chamber through valves of valve-timing mechanism. Multicylinder compressor whose shaft is coupled with shaft of electric motor supplied by storage batteries or dc generator is pneumatically connected with inlet branch pipes of cylinder-receiver. Inlet branch pipe of said compressor communicates with atmosphere through air filter.

EFFECT: increased efficiency of diesel engine, provision of uniform rotation and load on crankshaft, reduced discharged of non-combusted fuel.
