Grail Engine Adopts Enerpulse Pulse Plugs for Forced Semi-Homogeneous Charged Compression Ignition in Concept Two-Stroke Engine

Green Car Congress

HCCI is a combustion regime in which well-mixed fuel, exhaust gas and air are compressed to the point of auto-ignition. Unlike a spark ignition gas engine or diesel engine, HCCI produces a low-temperature, flameless release of energy throughout the entire combustion chamber. Elements of the Grail Engine.

Secondly, the central combustion chamber is benefit for highly efficient scavenging via intake and exhaust ports without using valves. The effects of [HCCI] operation will be investigated by future accurate combustion model. Furthermore, natural gas will be investigated as the fuel of the system. —Ling Huang 2012.
