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

Green Car Congress

SEPTEMBER 8, 2009

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.

Other features of the X2 include: Quiet operation: engine lacks poppet valves and over-expansion minimizes exhaust noise. By combining HEHC with a rotary engine architecture, LiquidPiston has created an engine that is up to ten times lighter, quiet, and two to three times more efficient at part-load than conventional engines.
