DIESEL WITH TURBO COMPRESSOR Russian patent published in 2015 - IPC F02M25/07 F02B37/18 

FIELD: engines and pumps.

SUBSTANCE: diesel with turbo compressor comprises cylinder (1) with piston (2), intake and discharge valve (4), (7), pipe (8) to feed exhaust gases from discharge vale (7) to turbo compressor turbine (9), pipe (6) to feed supercharging air from compressor (5) via heat exchanger (13) to intake valve (4) and recycling pipe (11) communicating the exhaust gas feed pipe (8) from exhaust valve (7) to compressor turbine (9) with supercharging air feed pipe (6). Pipe (8) to feed used gas from discharge valve (7) to compressor turbine (9) has bent section (10). Recycling pipe (11) is connected with bulged side of said bent section (10) for feeding the discharge gasses from discharge valve (7) to compressor turbine (9). Opposite end of recycling pipe (11) is connected with the bent section (12) at supercharging air feed pipe (6) of feeding supercharging air from compressor (5) to intake valve (4). Heat exchanger (16) is arranged in the recycling pipe (11).

EFFECT: decreased nitrogen oxide emissions.
