Start-up Eco-Motive developing dual-fuel “H” engine; parallel, independently fueled piston banks

Green Car Congress

The H-shaped engine comprises parallel left-side and right-side vertical inline piston banks, each having a crankshaft and pistons, a cylinder head, and individual fuel feeds, but sharing a common power transmission system. The selector control actuates a transfer system that prevents simultaneous operation of both engines.

Libertine FPE builds demo prototype of linear free piston generator

Green Car Congress

Already validated at proof-of-concept level, Libertine’s new hardware uses production-feasible component designs suitable for automotive hybrid powertrain modules, such as range extenders. Piston motion is the final major engine parameter that remains to be digitally controlled by the ECU rather than mechanically governed.

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

Green Car Congress

By over-expanding into adjacent de-activated cylinders, ECONAMIQ creates an additional power stroke within the existing engine architecture, with a significant thermal efficiency increase and cost savings as a result. Using the virtual simulation environment GT-Power, this cycle is applied to a 4-cylinder SI engine.

New split-cycle concept to control diesel HCCI combustion

Green Car Congress

The turbocharged concept allows reaching engine speeds of 6,000 rpm, with a high indicated efficiency of 45% along with clean combustion; power density at 6,000 rpm is 64 kW, with 300 kPa intake pressure. Thus the HCPC range can extend to all engine operating conditions, including very high loads. Tamagna, D.,

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

Green Car Congress

The Pulstar product offers very high power spark discharge, on the order of 1MW, to accelerate combustion pressures enabling forced semi-homogeneous combustion for all conditions. HCCI is a combustion regime in which well-mixed fuel, exhaust gas and air are compressed to the point of auto-ignition.

Concept: AET Reaches Final Development Stage of OX2 Barrel Engine

Green Car Congress

The engine can be adapted to run any combustible gas or liquid as fuel. Advanced Engine Technologies was incorporated in 1996 to commercialize the OX2, with automotive racing pioneer Carroll Shelby on its Board of Directors and involved in the engine development.
