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. Matthew Riley.

Achates Power developing light-duty two-stroke opposed-piston diesel engine: the OP4

Green Car Congress

Achates Power, which is developing a family of two-stroke, compression-ignition (CI) opposed-piston (OP) engines, has designed and is developing a light-duty diesel concept engine, the OP4. Exhaust temperature of the OP4 was 410 °C, compared to 246 °C for the baseline; the rate of exhaust enthalpy for the OP4 was 9.0

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

Green Car Congress

Air can be turned into a liquid by cooling it to around -196 °C using standard industrial equipment; 700 liters of ambient air becomes about 1 liter of liquid air, which can then be stored in an unpressurised insulated vessel. High efficiency internal combustion engine. The Dearman engine. Compressed air engines (e.g.,

LiquidPiston introduces latest X-series version of HEHC rotary engine; targeting 58% peak BTE, 2 hp/lb power density

Green Car Congress

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.
