Engine is the heart of automobile. Engine is the device that coverts heat energy of the fuel into mechanical energy. HCCI stands on homogeneous charge compression ignition. HCCI engine is an advanced combustion engine. In a HCCI concept, the fuel and air is pre mixed and compresses till auto ignition. It is developed to increase the fuel efficiency and reduce the emissions such as NOx and HC without sacrificing the efficiency such as NOx and HC. In HCCI engine homogeneous mixture of air and fuel is the key feature. HCCI engines allows Lean mixture of air and fuel. Hence it helps to reduce the NOx emission because lean mixture is cooler and cooler combustion makes less NOx and wastes less energy heating up the engine. HCCI engine have several difficulties such as, control of auto ignition, it producing heat more and weak capability in cold start. After studying the literature survey on HCCI engine, research work need to be done in this area because HCCI engine is the environment friendly combustion.
