EVALUATION OF THE HYDROGEN-SUPPLEMENTED FUEL CONCEPT WITH AN EXPERIMENTAL MULTICYLINDER ENGINE

Steady-state engine dynamometer tests were conducted with a specially modified multicylinder engine to determine if the improved lean operating ability of this engine would enhance the hydrogen-supplemented fule approach. The experimental engine did not benefit the hydrogen- supplemented fuel approach. At the lean mixtures required for very low NOX, the hot-engine hydrocarbon mass emission level was seven times the target for 1978 (0.41 g/mi) and approximately 60% greater than the minimum baseline level. The carbon monoxide mass emission level was approximately five times as great for supplementation with bottled hydrogen, and double the target for the 1978 standard of 3.4 g/mi. /GMRL/
