Libertine FPE builds demo prototype of linear free piston generator

Green Car Congress

Linear free piston engines can capture a much greater proportion of the energy contained in the fuel burnt, not only because the linear gas expander extracts electrical power directly from the expansion stroke, but also by optimizing the motion of the piston to improve combustion efficiency.

SEC issues cease-and-desist order against split-cycle engine developer Scuderi Group for violations of Securities Act

Green Car Congress

The Scuderi Engine is a split-cycle design that divides the four strokes of a conventional combustion cycle over two paired cylinders. The engine has two crossover passages that connect the two cylinders, which separate the four strokes of the pistons. a more efficient internal combustion engine.

Australian Cam-Drive Gasoline Engine Reaches 39.5% Efficiency in Independent Testing; Potential for Production Engine in China

Green Car Congress

The bearings are mounted on the underside of the two inter-connected pistons, which maintain the desired bearing-to-trilobe clearance throughout the stroke. The counter rotation is performed by a reverse gear set at a 1:3 ratio shaft providing two strokes of a piston to 360 degrees of output shaft rotation—the same as a conventional engine.

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

Green Car Congress

The injection of the additional air during transients can overcome the poor driveability usually associated with heavily downsized and supercharged engines, the team notes. In the pneumatic hybridization scheme, each cylinder is connected via a fully variable charge valve to a shared pressure tank. Dönitz et al. Source: ETH Zürich.

UK LowCVP Launches ‘Technology Challenge’ to Accelerate Low Carbon Vehicle Innovation; Libralato Engines First Registrant

Green Car Congress

Induction air enters at the center of the engine and compression/expansion occurs at the periphery producing uniform heat flow characteristics as air circulates around the two sides of the engine. The two rotors are connected together by a connection rod that has a quasi-circular orbit. Overview of the Libralato Engine.
