Hypergolic Combustion in an Internal Combustion Engine

D.H. Scharnweber, L. O. Hoppie

Abstract

Hypergolic combustion was experimentally investigated in a reciprocating internal combustion engine by means of preheating the fuel to about 1000°F (550°C) prior to direct cylinder injection. Ignition delay, exhaust opacity, and the rate of heat release were measured, and the potential for improved engine performance was demonstrated.
