Global warming caused by greenhouse gases are currently a significant problem in the world. Hydrogen is regarded as one of the possible sources of energy for the future. Hydrogen fueled engines emit no carbon dioxide as tank-to-wheel. Hydrogen engines can reduce greenhouse gases in comparison to engines fueled with fossil fuels. A pre-mixed hydrogen-fueled engine, specifically, can be put into practical use in a short period of time from a technical point of view. However, there are some technical issues, such as backfiring and low power output to resolve. With the aim to put a pre-mixed hydrogen-fueled engine for trucks and buses into practical use, it is necessary to prevent backfiring and to develop a high output engine. A diesel engine modified as a pre-mixed hydrogen-fueled engine was equipped with a variable geometry turbo-charger for higher output.
