HCCI combustion is expected to enable the internal combustion engines to operate with higher thermal efficiency and cleaner exhaust emissions compared to conventional combustion systems. However, a difficulty in ignition timing control is a major problem preventing it from practical applications to automobiles. Adjusting the proportion of two fuels having different ignitability can be a solution to this issue. There is a report on effective ignition control with combining dimethylether and hydrogen. On the other hand, ammonia can be a hydrogen carrier in the hydrogen energy society in the future. This current research investigates the effect of ammonia addition to HCCI combustion on the ignition timing.
