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.

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

Green Car Congress

An adaption of cylinder de-activation technique called ECONAMIQ over-expansion can be applied to engines to improve fuel efficiency. Using the pressure from the exhaust gas from the active cylinders, the ‘idle’ cylinders could be expanded to extract more work out of the engine during partial load operation.

Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

Schematic of downsized and supercharged four-stroke hybrid pneumatic spark injection engine. The HPE was long thought to be a system in which all engine valves had to be actuated in a fully variable manner to allow for two-stoke pneumatic modes and still enable the four-stroke combustion mode.

Liquid Air Energy Network forms in UK; focus on transportation and energy storage

Green Car Congress

A new new forum for the advocacy and development of liquid air as an alternative technology to harness waste and surplus energy within power and transport—the Liquid Air Energy Network (LAEN)—has formed in the UK. Sources of low-grade waste heat include power stations to factories to vehicle engines.
