The paper describes combustion anomalies of various types randomly or permanently occurring while hydrogen is burnt in a supercharged spark ignited reciprocating engine. The anomalies were mainly identified as result of combustion pressure data analysis. Originally, the engine was a compression ignition one fuelled with diesel fuel. Modifications done on the engine dealt with decrease in its geometric compression ratio and equipping it with a spark plug located in diesel fuel injector position. The anomalies presented in the paper are typically associated with several abnormal phenomena as follows: flame propagation into intake manifold called back-fire, hydrogen spontaneous ignition by hot surface, flame propagation during valves overlap and extinguishing spark discharge flame kernel by high turbulence around a spark plug. These anomalies were observed in the supercharged engine, however, some of them were also detected while the engine was operated as a freely aspirated one. As investigated, some of these malfunctions would have been removed by change in engine operating parameters. Others need major changes in both exhaust pipeline geometry, hydrogen injection system, engine cylinder geometry and valve timing.
