FIELD: engines and pumps.
SUBSTANCE: at engine adjustment at its rpm higher than average magnitude, exhaust gases are forced to intake valve 7. At shaft mean and lower rpm, exhaust gases are forced to inlet o compressor 9 of turbocompressor 10. At reduced load at engine, exhaust gases are forced to valve 7 and to inlet of compressor 9. At engine running under conditions that allow detonation, exhaust gas circulation is terminated to force a portion of supercharging air to compressor 9 inlet.
EFFECT: higher operating and fuel efficiency, decreased nitrogen oxide emission.
