Hydrogen and Spark Ignition Engine.

Industry Reports on hydrogen fuel systems

From the above study it is evident that Hydrogen and various experimental approaches have been adopted for enhancing the efficiency in spark ignition engines. Along with these a considerable research has also been done using the simulation tools to help predict the effect of various parameters on engine performance. The research done proves that ydrogen gas can be further used for complex combustion, emission and efficiency analysis in spark ignition engines.

The blending of hydrogen reduces the specific fuel consumption, while ethanol blending increases the specific fuel consumption. More information on this study can be seen on the following linked document
