Abstract: Homogeneous Charge Compression Ignition is the mode of engine which will provide the advantages of both the SI and CI engine and consider as an alternative to the gasoline and diesel engine due to its capability of very low NOX emissions and operating with higher efficiency. The HCCI concept involves pre-mixing of charge prior to its induction as in present Spark Ignition (SI) engine, then ignite the air fuel mixture through the compression as in Compression Ignition (CI) engine and has no throt tle loss, which leads to high efficiency. HCCI engine can operate on gasoline, diesel and most of the alternatives fuels. In HCCI, the combustion occurs simultaneously throughout the cylinder volume, as opposed to the turbulent flame propagation or mixing controlled combustion used in conventional engines. Instead of having advantages there are some challenges to the operation of the HCCI Engine. The main limitation of HCCI is the narrow operating window which results from the lack of direct ignition timing control. This paper reviews the technology involved in HCCI engine development, its advantages and disadvantages. The challenges involved in HCCI and the future developments in the same are also discussed in the paper.
