Since emission measurements from passenger cars are performed at one standard set of ambient conditions and since emission rates of HC, CO, and NOx are sensitive to temperature and humidity, it is necessary to determine the influence of ambient conditions on emissions from major classes of vehicles. Although such information has been available for gasoline engine powered cars for sometime, no such data were available for diesel powered passenger cars. This report indicates that diesel HC and CO emissions are relatively insensitive to ambient conditions. Diesel NOx emissions, however, are sensitive to humidity but to a smaller extent than gasoline engines. Humidity correction factors for NOx emissions also appear to vary with vehicle power-to-weight ratios and are greater for higher powered vehicles.
