The use of various alternative and modified fuels in diesel engines was investigated as a method for controlling particulate and oxides of nitrogen emissions. The effect of these fuels on the carbon monoxide and hydrocarbon emissions was also documented. The test fuels were screened using a caterpillar 3304 diesel engine converted to single-cylinder operation. Selected fuels were subsequently evaluated using full-scale engine tests. Engine modifications were made to optimize the performance of the alternative fuel. Transient and steady-state emissions data are reported for the optimized and baseline engine. The effects of the transient operation of the engine on the exhaust emissions were investigated. A method was developed for predicting transient cycle exhaust emission based upon the cycle speed and torque profile and steady-state emissions data.
