INTERNAL COMBUSTION ENGINE Russian patent published in 2005 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: invention can be used in drives of vehicles and other movable and stationary consumers of mechanical energy. Proposed internal combustion engine contains paired communicating cylinders having independent supply system and crank mechanism providing definite advance of movement of piston of one cylinder, named low compression cylinder, relative to piston of other cylinder, named high compression cylinder. Engine is furnished additionally with regulated heating device, controlled electromagnetic valve, ejector, mixer, boost pump, direct injection controlled system, and controller. Supply systems of both cylinders contains fuel tank filled with low boiling liquid, for instance, MDE, with heating device controlled by controller providing constant temperature level inside tank. Supply system of low compression cylinder includes electromagnetic valve operated by controller installed I upper part of tank, nonadjustable ejector, whose active and passive nozzles are connected with outlet of electromagnetic valve and with ambient medium, respectively, mixer one inlet of which is coupled with ejector outlet and second inlet, with ambient medium and outlet, through intake valve, with low compression cylinder. Supply system of low compression cylinder includes boost pump whose inlet is coupled with lower part of tank, and outlet is connected with liquid fuel direct injection system for high compression cylinder, system being controlled by controller.

EFFECT: provision of internal combustion engine featuring high performance characteristics, low consumption of fuel and no pollution of ambient atmosphere.
