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. Ignition occurs via the sparkplugs.

The first registrant in the Challenge is Libralato Engines, developer of a novel rotary engine (cutaway shown) promising a 5.5% gain in combustion efficiency and 50% reduction in NO x emissions. Rotor 1, Rotor 2 and the connecting cam form the total internal mechanism of the engine. Click to enlarge.

In its chapter, Ricardo considered a number of potential roles for liquid air considered in which the air is used as a heat sink and then as a working fluid within a heat engine. The heat engine can be deployed as either the prime mover or in a supporting role to recover waste heat from a conventional engine or fuel cell.

High-pressure air jet controlled compression ignition (JCCI) is based on a compound thermodynamic cycle and is implemented in a hybrid pneumatic engine (HPE) as proposed by Schechter in 1999. The application of HPE is also beneficial to the fuel consumption and emissions because of its several flexible operation modes.

The prototype is of the naturally-aspirated Split Cycle gasoline engine, and is intended to be a proof of the basic technology of the split cycle with firing after Top Dead Center (one of the key attributes of the engine and cycle). As a result, Scuderi said, combustion is four times faster than in a conventional engine.
