Amelioration of Combustion of Hydrogen Rotary Engine

Hydrogen rotary engines are promising power sources for the future hydrogen society, and improving their thermal efficiency helps propel tomorrow's car farther. This research looked into the combustion process to reduce fuel consumption. Primary studies of combustion duration and location showed that increasing the local mass burning rate in the L-side of the combustion chamber by generating turbulence was beneficial. Experiments with optical and real rotary engines proved that turbulence effectively increased mass burning rate in L-side and consequently engine's thermal efficiency and its lean limit
