Simulation analysis of working conditions with alternative fuels for HCCI Engine

The Internal Combustion (IC) Engine is perhaps the most wide-spread apparatus for transforming liquid and gaseous fuel to useful mechanical work. Homogeneous charge compression ignition (HCCI) is a new combustion technology that may develop as an alternative to diesel engines with high efficiency and low NOx and particulate matter emissions. The homogenous charge compression ignition (HCCI) is a promising new engine technology that combines elements of the diesel and gasoline engine operating cycles. HCCI as a way to increase the efficiency of the gasoline engine. The attractive properties are increased fuel efficiency due to reduced throttling losses, increased expansion ratio and higher thermodynamic efficiency. The main drawback of HCCI is the absence of direct combustion timing control. Therefore all the right conditions for auto ignition have to be set before combustion starts. The work involves the past and current research done on HCCI engine. Many research got considerable success in doing detailed modeling of HCCI combustion. The work aims at studying the fundamentals of HCCI combustion, the strategy to control the limitation of HCCI engine. and finding optimum operating conditions for HCCI engine operation. The purpose of this work, on the combustion timing and the optimal work operating zone for HCCI engines. There are also many challenges still to investigate HCCI Combustion Process, a detail Simulation approach will be used to limit the drawback of HCCI Engine.
