Optimizing a spark-ignition engine fuelled with methane using a two-zone combustion model
Methane which can be produced from biogas has a great potential to be used as an alternative renewable fuel for spark-ignition engines.However, engines need to be optimized for methane use.The aim of this study was to numerically optimize a spark-ignition engine fueled with methane and operated at a constant speed of 1,500 rpm via using a validated
