This article discusses the results of many tests for evaluating the performance and environmental impacts of alternative motor fuels and engines. The tests have been conducted by VTT for the International Energy Agency (IEA). Their results show that natural gas and liquid petroleum gas are inherently clean fuels. They give low emissions in all conditions where up-to-date engine technologies are used. One of the IEA's main tasks is Performance Evaluation of Alternative Fuel/Engine Concepts, whose main objectives are to: (1) generate comparable information on the true emission potential of alternative fuel concepts in severe operating conditions; (2) determine and improve the serviceability of alternative fuel concepts in these conditions; and (3) collect data on and apply new emission measurement technology. The engine tests showed that fuel choice and test temperature can both strongly influence regulated and unregulated emissions. Eleven light-duty vehicles were tested on a chassis dynamometer, for 112 combinations of vehicles/fuels/temperatures. Alternative fuels tested included methanol and formaldehyde. VTT will continue its experimental work within its agreement with the IEA, and will extend testing to diesel engines.
