The combination of discrete, asymmetrically sized cylinders and fully variable valvetrain promises the ability to vary displacement ratios, bore-stroke ratios, compression-expansion ratios, compression-expansion phasing, and gas transfer phasing for engine optimization—i.e., a more efficient internal combustion engine.

When reforming is not used, the fuel and exhaust pass through CV2 unchanged. A paper on their work was published online 5 February in the ACS journal Energy & Fuels. The basic concept of TCR involves using exhaust heat to promote on-board reforming of hydrocarbon fuels into syngas (a mixture of carbon monoxide and hydrogen).

Subsequent implementation of the Split Cycle will be a turbocharged split cycle unit, an air hybrid version of the engine, and a diesel-fueled version. The one-liter, naturally-aspirated gasoline prototype is expected to produce up to 80% fewer criteria pollutants than a typical internal combustion engine. Engine speed.
