INTERNAL COMBUSTION ENGINE Russian patent published in 2015 - IPC F02M25/07 F02D21/08 F02B37/16 F02B37/18 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in engine-building. The internal combustion engine contains the cylinder with the piston, inlet and outlet valves (7) and (1), a turbocompressor (10), a channel (8) for air passing from the turbocompressor (9) to the inlet valve (7) and the channel (4) for passing of exhaust gases from the outlet valve (1) to the turbocompressor turbine. The engine contains the multiposition distributor (5) in one of positions interconnecting the channel (4) for passing of exhaust gases through the recirculation channel (2) with the inlet valve (7). In other position the multiposition distributor (5) interconnects the channel (4) for passing of exhaust gases through the recirculation channel (2) with an inlet to the compressor. In the third position the multiposition distributor (5) interconnects the channel (8) for air passing from the compressor (9) with the inlet to the compressor and the recirculation channel (2). The operated valve (3) is installed in the recirculation channel (2) between the channel (4) for passing of exhaust gases from the outlet valve (1) to the turbocompressor turbine and the multiposition distributor (5).

EFFECT: decrease in nitrogen emissions.
