Recent progress on the Ammonia-Gasoline and the Ammonia-Diesel Dual Fueled Internal Combustion Engines in Korea

Both a spark ignition engine and a compression ignition engine are considered to use ammonia as primary fuel in this study. First, in a spark ignition engine, an ammonia-gasoline dual fuel system was developed and both ammonia and gasoline are injected separately into the intake manifold in liquid phase. As ammonia burns 1/6 time slower than gasoline, the spark timing is needed to be advanced near 40 degree before top dead center. The test engine showed quite high variation in the power output with ammonia supply more than 70% of the total heat value. As a result, 70% of gasoline…
