ECONAMIQ: Flexible over-expansion with cylinder deactivation can reduce ICE fuel consumption by up to 20%

Green Car Congress

Dutch start-up ECONAMIQ is developing a novel engine technology which saves up to 20% in fuel consumption. The “ECONAMIQ principle” uses flexible over-expansion in combination with cylinder deactivation technology to increase performance and efficiency without significantly changing the engine layout or architecture.

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. Ignition occurs via the sparkplugs.
