Engine emission control system and method

An exhaust filtration system kit for a diesel engine powered device, comprising:

• a valve comprising first and second opposed openings, said first opening adapted to be coupled to an exhaust conduit of said device and said second opening adapted to be coupled to an exhaust conduit of said device, said valve further comprising a third opening adapted to be coupled to a filtration system conduit;
• a valve actuator coupled to the valve for moving the valve between an open state and a closed state;
• a control switch electronically coupled to the valve actuator for switching the valve actuator between an engaged state and a disengaged state;
• a wireless receiver coupled to the control switch for receiving a radio frequency signal from a wireless transmitter and for sending a signal to the control switch;
• and
• a wireless transmitter for generating a radio frequency signal.

A method for controlling an exhaust filtration system on a device having a diesel engine, a diesel exhaust filter, a valve that directs exhaust to the filter in an engaged state and that directs exhaust away from the filter in a disengaged state, and a valve actuator that moves the valve between the engaged and disengaged states, comprising the steps of:

• placing a radio frequency transmitter in a location where it is desired to have the filter in an engaged state if the device is present at the location;
• and
• providing a radio frequency receiver coupled to the valve actuator,
• wherein the receiver causes a signal to be sent to the valve actuator if the receiver receives a radio frequency signal from the transmitter and said signal causes said actuator to move the valve to the engaged state.
