FIELD: engines and pumps.
SUBSTANCE: proposed system comprises filter 13 to entrap solid particles and catalyst neutraliser 11, 12. System is arranged so that, in changing over to engine operation conditions whereat amount of sucked in air (GA) is smaller during secondary injection and amount of fuel injected during secondary injection decreases to decrease amount of fuel that sticks to cylinder inner walls, thus, limiting oil thinning by fuel, fuel being intended for lubing ICE 1. Secondary injection is not interrupted but volume of secondary injection is decreased. Therefore, when frequent changing from smaller amount of sucked-in air to larger amount of sucked-in air and visa versa, filter temperature does not decrease notably in changing to smaller amount of sucked-in air. Then changing to larger amount of sucked-in air, increasing filter temperature to degree required for combustion of solid particles does not required much time.
EFFECT: reduced time filter regeneration.
