Motiv Engines introduces 2nd-generation split-cycle concept; MkII Clarke-Brayton heavy-duty engine being designed for LNG

Green Car Congress

The thermodynamics of the engine are virtually identical to the company’s previous CCI (Compact Compression Ignition) design, as described in a 2013 SAE paper, but are implemented in a much more conventional way. It achieves this by splitting the processes of an engine into three separate optimized spaces—i.e.,

Dalian team proposes jet controlled compression ignition to control PCCI phasing in a hybrid pneumatic engine

Green Car Congress

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. Schechter, M.
