The University of Denver has developed a remote sensor for in-use motor vehicle hydrocarbon (HC) and carbon monoxide (CO) emissions. Under this contract the authors have explored the possibility of using a police type radar unit to measure vehicle speed and acceleration in conjunction with the vehicle's remotely sensed HC and CO emissions. Vehicle speed was determined accurately, however, acceleration measurements need improvement. A fleet of vehicles in Toronto, Canada was characterized for its CO emissions. It is a very new and low emitting fleet despite the lack of a routine inspection and maintenance program. A subset of the fleet was propane powered and appears to have about double the emissions of the gasoline powered fleet. The possibility of adding a water vapor channel to the remote emissions sensor was examined. Full testing of the channel has yet to be done but there is hope that the sensitivity will be sufficient to allow separation of cold engine from warm engine operating modes.
