FIELD: engines and pumps.
SUBSTANCE: invention relates to recovery of diesel carbon-black filter in diesel engine system 1. This system comprises combustion chamber arranged in cylinder with piston reciprocating therein, discharge valve for combustion chamber cyclic opening relative to discharge line 40 and diesel carbon-black filter 7 in said discharge line 40. Proposed method comprises injection of fuel portion in combustion chamber by two sequential after-injection pulses AIP1-AIP3, each starting SOI after the piston passes TDC and sufficiently near the latter to make fuel burn at least partially inside combustion chamber.
EFFECT: higher efficiency under all operating conditions.
