Through the cooperation of several organizations including the Oak Ridge National Laboratory (ORNL) acting under the auspices of the Doe Alternative Fuels Utilization Program, heavy duty transient and steady-state emissions tests were conducted on four alternative fuel configurations of the Caterpillar 3406 engine. These included a diesel baseline, glow plug ignited methanol (diesel cycle), lean-burn spark ignited natural gas, and dual fuel (diesel pilot ignited natural gas). Results indicated methanol and natural gas both show excellent potential for low NOx and low particulate emissions. With these fuels however, unburned fuel emissions were much higher, especially in the dual fuel case, than the diesel baseline. Particulate emissions from the methanol and lean burn gas engines are thought to be almost entirely lube oil sourced. All of the configurations will require significant reduction in hydrocarbon and/or particulate emissions in order to meet the 1994 EPA emissions standards for heavy duty truck engines. 3 refs., 23 figs., 15 tabs.
