Index decomposition analysis (IDA) has been a popular tool for studying changes in energy consumption over time in major energy consuming sectors. In the basic form, it allows such changes to be decomposed to give contributions associated with three different effects, namely activity, structure...

The performance of a hydrogen-blended gasoline engine at lean and the wide open throttle conditions was investigated. A hydrogen port-injection system was adopted to introduce the hydrogen into each cylinder. The engine was operated at 1400rpm and two hydrogen blending levels of 0% and 3%. The...

This paper proposed a new combustion strategy for the spark-ignited (SI) engines. A gasoline engine was converted into a hybrid hydrogen–gasoline engine (HHGE) by adding a hydrogen injection system and a hybrid electronic control unit. Different from the conventional gasoline and...
