Exhaust gas abatement device for vehicles equipped with diesel engines

摘要

The present invention is characterized in that a secondary exhaust pipe (4) for bypass is installed on the main exhaust pipe (2) of a vehicle equipped with a diesel engine and the catalytic converter (3) The first and second shutter valves 5a and 5b and the first and second actuators 6a and 6b mounted on the tip of the auxiliary pipe 2 and the actuators 6a and 6b are connected to each other, A temperature detection sensor 13 connected to the vacuum pump 9 via the first and second solenoid spokes 8a and 8b and mounted on the leading end of the catalytic converter 3 on the main exhaust pipe 2, The switch stages 11a and 11b of the two solenoid valves 8a and 8b are controlled by the engine control computer 13 so that the exhaust gas is supplied to the catalytic converter 3 when the temperature of the exhaust gas is 350 [ So that the exhaust gas is discharged to the outside through the auxiliary exhaust pipe 4 without being obstructed, and the exhaust gas is supplied to the oxidation catalyst in the catalytic converter 3 Sulfur gases generated by the present invention relates to an exhaust gas reducing device of a vehicle equipped with a diesel engine that emits ever prevented.
