Achates Power, which is developing a family of two-stroke, compression-ignition (CI) opposed-piston (OP) engines, has designed and is developing a light-duty diesel concept engine, the OP4. Throughout emissions cycle load points, the OP4 demonstrated 0.4 g/kWh engine-out NO x. Diesel Engines Fuel Efficiency'

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.
