“…The high compression ratios required to autoignite the mixture can result in efficiency comparable to CI engines, assuming that the indirectly controlled ignition begins at the appropriate moment. HCCI engines provide fuel flexibility because they can run on some fuels including gasoline, 1 diesel, 2 and alternate fuels 3 . Although HCCI engines have many of the beneficial qualities of SI and CI engines, they add the challenging jobs of managing the start of combustion (SOC) and possess a restricted load spectrum that cannot meet the heavy load demands necessary for automobiles 4 .…”

The current study presents research investigations and developments related to the homogeneous charge compression ignition (HCCI) engine. Research investigations and recent advances, including the role of various operating conditions on HCCI engine combustion phenomena, emissions, and performance, are discussed. There is growing research interest in investigating HCCI engines with diesel fuel to study combustion, emissions, and performance characteristics due to their association with low NOx emissions. In the published literature, research investigations are also conducted with different fuels ranging from biomass to diesel to gasoline in the HCCI engine showing its capability for utilizing various fuels in coming years. The challenges associated with HCCI combustion are reviewed, and the details of excessive carbon monoxide and unburnt hydrocarbon emissions are discussed. The major parameters affecting the hydrogen addition in HCCI diesel engines are also discussed. Overall, adding hydrogen to a diesel‐fueled HCCI engine improves combustion phasing and can potentially increase thermal efficiency while lowering emissions. In addition, the strength, weaknesses, opportunities, and threat analysis is provided and discussed thoroughly.
