A comparative evaluation of six transit bus engines (three diesel, one propane (LPG), one natural gas for vehicles (NGV), and one methanol) has been performed. The purpose of the program was to assess the exhaust emissions and fuel consumption of current state-of-the-art large alternative fuel engines. Engine dynamometer test work was performed at the Ontario Research Foundation (ORF) which allowed a detailed comparison of several alternative-fuelled engines versus their diesel counterparts. Test data includes steady-state brake-specific fuel consumption maps, torque and horsepower curves. Transient performance, fuel consumption and emissions information came from computer-controlled engine dynamometer runs of the Advanced Design Bus (ADB) test cycle.
