A study of combustion and engine performance using electronic hydrogen fuel injection

An experimental study was conducted using electronic hydrogen fuel injection in the intake manifold of a single cylinder spark-ignition engine. The purpose of the study was to investigate cyclic variations and backfiring and to determine if timed manifold injection provides any advantages over hydrogen carburation. It was found that injection improved cyclic pressure variations and practical lean operating range. A small improvement in thermal efficiency was also observed in the lean region. Based on limited work using timed port injection it seemed that backfiring could be controlled.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/25001/1/0000428.pd
