An adaption of cylinder de-activation technique called ECONAMIQ over-expansion can be applied to engines to improve fuel efficiency. Using the pressure from the exhaust gas from the active cylinders, the ‘idle’ cylinders could be expanded to extract more work out of the engine during partial load operation.

The expansion of the liquid air when heat is reintroduced can be used to drive a piston engine or turbine to do useful work. The main potential applications are in electricity storage, transport and the recovery of waste heat. High efficiency internal combustion engine. The Dearman engine. Compressed air engines (e.g.,

It compresses the pressurized gas produced by exhaust gas turbocharger, comprising fresh air and exhaust gas introduced from the EGR valve. Compound HPE is divided into a compressor cylinder and a power cylinder, combined with a compressed air storage tank. Then it charges the compressed air storage tank.
