Patent ID: 7743604

Claim:
A system for providing heat to a dump body of a dump truck using exhaust, comprising a diesel engine, an exhaust stack having a venting end, a diesel particulate filter having an input and an output for exhaust gas, exhaust gas from said diesel engine being routed to the input of the diesel particulate filter, and, an exhaust temperature control module, the exhaust gas output from said diesel particulate filter being routed to said exhaust temperature control module, said exhaust temperature control module comprising: i) temperature sensing means, said temperature sensing means including a first temperature sensor, and, ii) exhaust-diverting means, said exhaust-diverting means including a movable diverter member; wherein said exhaust temperature control module controls: i) said diverter member for movement to a position where exhaust gas is diverted to the dump body when the exhaust gas temperature is sensed by said temperature sensing means to be at or below a predetermined threshold temperature, and, ii) said diverter member for movement to a position where the exhaust gas bypasses the dump body when the exhaust gas temperature sensed by said temperature sensing means exceeds the predetermined threshold temperature.
