The Effect of Compression Ratio on Combustion and Performance Characteristics of Direct Injection Spark Ignition Hydrogen Fueled Engine.

직접분사식 스파크점화 수소기관의 연소 및 성능특성에 미치는 압축비의 영향

As fundamental step to find the suitable compression ratio of hydrogen fueled engine, performance and combustion characteristics of that engine were analyzed. Qualitative characteristics of the hydrogen fueled engine were similar to that of the gasoline engine, and it was also found that knock limit compression ratio of the hydrogen fueled engine was higher than that of the gasoline engine.
