Abstract: HCCI (Homogeneous Charge Compression Ignition Engine) is a new mode of combustion which leads to the development of ICE. HCCI engine is an alternative to the present day diesel engine with higher thermal efficiency. To reduce the effect of pollutants, the development of engines by improving the technology and by friendly combustion process, the engines are able to achieve/meet the future emission standards. The recent advancement in HCCI engine, has meet these standards by reducing the NOx and soot emissions up to 85-90% and also by increasing its thermal efficiency 10-15% more than the present day gasoline and diesel engine. HCCI engines are operated upon gasoline, diesel, natural and most other alternate fuels. HCCI engines incorporated with the best features of both spark ignition (SI) and compression ignition (CI) engines. However, HC and CO emissions are slightly higher as compared to CI engines. So, the usage of methods like EGR (Exhaust Gas Recirculation), variable fuel ratio, and by variation of induced gas temperature. The paper looks in to the ignition timing of the HCCI engine and the factors effecting (or) depending to increase efficiency. Also the methods to required characteristics of HCCI engine.
Keywords: HCCI Engine, EGR (Exhaust Gas Recirculation), spark ignition (SI), Compression Ignition (CI).
