Analysis of Direct Injection Spark Ignition Combustion in Hydrogen Lean Mixture 2000-05-0089

Characteristics of methane direct injection spark ignition stratified combustion in lean hydrogen mixture were analyzed both in a single cylinder engine and in a constant volume combustion vessel. Combustion pressure and instantaneous combustion chamber wall temperature during combustion process were measured and used in analysis of combustion and cooling loss. Results in this research show the premixed hydrogen increases cooling loss to combustion chamber wall while achieving combustion promotion, and the combustion system is effective especially in lean mixture conditions. Analysis of flame propagation was also done with schlieren photography in the constant volume combustion vessel.
