FIELD: engines and pumps.
SUBSTANCE: invention may be used in supercharge diesels. Proposed method is intended for diesel (1) including pipe (2) to feed air into diesel (1), diesel exit gas exhaust pipe (3), diesel soot filter (31) arranged in exhaust pipe (3) and exit gas circulation system (50, 60) to return exhaust gas into diesel (1). Exhaust gas circulation system comprises off-gas circulation line (60) to receive exhaust gas from exhaust pipe (3) downstream of soot filter (31). Method of diesel control consists in setting the threshold (Sth) for amount of soot getting into off gas circulation system. Besides, actual amount (Saa) of said sooth is defined. Now, the procedure of off-gas circulation line protection is actuated if actual amount (Saa) is higher than said threshold (Sth). Besides it discloses the device to this end.
EFFECT: reduced sooting.
