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.

Engineers from Honda R&D Co., presented a pair of papers at the SAE 2009 World Congress describing the development of a variable compression ratio (VCR) engine enabled by a dual piston mechanism. For the study, Honda installed a small pump separate from that of engine lubricating oil pump. Kadota et al. Ishikawa, K.

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.

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.

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.
