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.

Motiv Engines introduces 2nd-generation split-cycle concept; MkII Clarke-Brayton heavy-duty engine being designed for LNG

Green Car Congress

It expands all the way to ambient pressure before the exhaust stroke. The power is produced in almost a 50-50 split between the combustion (central) and exhaust (largest) pistons. Transfer from the combustion cylinder to the exhaust cylinder takes place when the exhaust cylinder volume is minimal. 27-1, book G1011A, 1996.

Concept: Garric Rotary Variable Compression Ratio Engine

Green Car Congress

The project will take the Garric design from its current advanced concept stage to development of a fully functional prototype, according to the company. The Garric engine has been to operate on a wide variety of liquid and gaseous fuels. It also directs the spent exhaust gasses out of the torus.

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.
