|Title:||Comparative Performance of Two Postal Service Vehicles Operated on Gasoline, Compressed Natural Gas and Propane|
|Published:||November 17, 1974|
|Abstract:||The operational and exhaust emission characteristics of a 1/2-ton and a 1-ton truck run on three different fuels gasoline, compressed natural gas (CNG) and liquefied petroleum gas or propane (LPG) were measured. The vehicles were put into an environmental chamber so that the rear wheels rested on a chassis dynamometer. In the series of tests, ambient temperature was controlled at various levels between 1 and 110 F and a range of spark advance settings and air-fuel rations were used on the engines. The vehicles were run at various dynamometer loads and simulated speeds ranging from idling to 50 mph. HC, CO, and NOx emissions were measured and the results showed to what extent the various pollutants could be reduced by suing the alternate fuels (CNG or LPG).|
