HIGH COMPRESSION RATIO INTERNAL COMBUSTION ENGINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; power plants. SUBSTANCE: fixed working pistons with cooling jacket, exhaust valves and unit injectors to supply fuel and water and laser beam guide are installed in upper part of engine cylinder block. Supercharging pistons with cooling jacket and branch pipe with automatic air valve are installed in lower part of cylinder block. Paired through bottoms coaxial working cylinders with supercharging cylinders cast integral and communicating through automatic bypass valve are placed between pistons for moving in horizontal direction. Guide vanes are arranged in bypass valve housing. Guide vanes provide swirling multistart movement of air providing swirl air cyclone in working cylinder into which direct injection of fuel is provided by unit injector. Cooling wells are provided between bottoms of integral cast coaxial cylinders. Lubricating and cooling non-freezing liquid is pressure fed into cooling wells. Segment cutoff is made on upper half of bottom in each fixed piston. EFFECT: increased efficiency, service life of engine and reduced toxicity of exhaust gases. 3 cl, 2 dwg
