Patent ID: 7987667

Claim:
A system for removing particulates from exhaust gas of a vehicle internal combustion engine, comprising: first gas flow means connected to an exhaust of said engine; valve means connected to said first gas flow means for normally directing exhaust to a first output, when in a non-activated or deactivated condition, and for directing exhaust to a second output, when in an activated condition; second gas flow means connected to said valve means first output for exhausting particulate-containing exhaust to the atmosphere; third gas flow means connected to said valve means second output for removing exhaust gas particulates before delivering said exhaust gas to the atmosphere; means responsive to starting of said engine for activating said valve means for a predetermined period of time; exhaust pressure sensing means for monitoring exhaust backpressure, said sensing means operatively connected to means for indicating the filter medium loading status of said exhaust gas particulate removing means; circuit means responsive to said exhaust pressure sensing means for maintaining said valve means continuously in said non-activated condition, when said exhaust backpressure reaches a predetermined level for a predetermined period of time; locking means for disabling other system inputs that normally would activate said valve means, when said exhaust backpressure reaches said predetermined level for said predetermined period of time; and further comprising means for receiving and storing GPS coordinates of one or more exhaust sensitive areas and activating said valve means when said vehicle comes within a predetermined distance of said exhaust sensitive area(s).
