How HCCI engine works. ✔ HD

This video explains the working of HCCI Engine (homogenous charge ignition engines). This engine is a combination of compression ignition engine (diesel engine) and Gasoline engine (spark ignition engine) hence also called as a Hybrid engine. The strokes involved are: Suction: Inlet valve opens and air fuel mixture is sucked in. Compression: Air fuel mixture is compressed, all valves in closed condition. Combustion: The air fuel mixture is a lean mixture (air to fuel ratio is high), so during compression temperature rises and about 700 degree celsius combustion occurs at all valves in closed condition. Exhaust: exhaust valves opens and exhaust happens. Advantages: Less pollution as Nox produced is less due to flameless ignition. 15% more efficiency compared to that of diesel and gasoline engines.
