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. Matthew Riley.
