ABSTRACT:
A system for removing particulates from the exhaust gas of a vehicle internal combustion engine, particularly during those times that the emission of such particulates into the atmosphere would be of greatest danger to persons in the vicinity of the vehicle, includes a valve connected to the vehicle exhaust manifold for normally directing exhaust to the atmosphere, when in the non-activated condition. The valve directs exhaust to a particulate filter, when in the activated condition. Starting of the engine activates the valve for a predetermined period of time. The valve optionally is GPS-controlled and can be disabled manually or automatically by a switch, which detects the backpressure in the exhaust system. An exhaust pressure sensor monitors the exhaust backpressure, and a circuit device responsive to the exhaust pressure maintains the valve continuously in the non-activated condition, when the exhaust backpressure reaches a predetermined level for a predetermined period of time.
