COLD AMBIENT TEMPERATURE EFFECTS ON EMISSIONS FROM LIGHT-DUTY MOTOR VEHICLES

An emission testing program conducted at Ottawa, Canada, indicated that the start-up and operation of light-duty motors at an ambient temperature of O degrees F. produces approximately a 100% increase in hydrocarbon and carbon monoxide emissions when compared with those produced at an ambient temperature of 60 degrees F. This increase appeared to occur mainly during the initial 5 min of engine operation. /GMRL/
