Abstract
One possible solution for the reduction of pollutants from internal combustion engines is the use of gaseous fuels such as natural gas or propane. The best application for the use of these fuels appears to be with fleet operators. The federal government operates between 300,000 and 400,000 vehicles which makes it an excellent candidate for using them. This paper describes a laboratory investigation in which the power output and pollutant levels of two Postal Service vehicles equipped with dual-fuel systems, were determined at simulated road conditions in an environmental chamber at temperatures from 0 deg F to 100 deg F.
