FIELD: engines and pumps.
SUBSTANCE: invention relates to heating of pipeline feeding reducing agent for selective catalytic reducing agent in operation of the system intended for reduction of off-gas toxicity. Invention covers the method of selecting heating of pipeline (8) feeding reducing agent for selective catalytic reducing agent in operation of the system (20) intended for reduction of off-gas toxicity in operation of ICE (7). Besides it covers off-gas toxicity reducer (1) with service tank (2) to store reducing agent (4) used for selective catalytic reduction. Also, it includes device (5) to feed reducing agent (4) to ICE (7) exhaust pipe (6) and at least one reducing agent feed pipe (8) for connection of service tank (2) with reducing agent feeder (5).
EFFECT: minimised power consumption, efficient reduction of toxicants in off-gas.
