EFFECT OF COLD WEATHER ON MOTOR VEHICLE EMISSIONS AND FUEL CONSUMPTION-II

The effect of soaking temperature on exhaust emissions and fuel consumption was investigated using a variety of automobiles representing different emission control levels including diesel engine powered vehicles. Tests were performed at soaking and ambient temperatures of 20 degrees C down to -20 degrees C (68 Degrees F to -4 degrees F). It was found that emissions and fuel consumption are dependent on soaking temperature. It appears that temperature sensitivity of fuel consumption in vehicles equipped with diesel engines and lean burn gasoline engines is considerably lower in comparison to the vehicles equipped with other control technologies.
