The Eco-Motive H-motor—basically two separate engines housed within the same engine block—can be powered by either gasoline or compressed natural gas (CNG), at the driver’s decision. The H-motor is fed by dual gas tanks on either side of the drive shaft. Concept Engines Engines Natural Gas'

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.

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.

A researcher at the Nanjing University of Science & Technology is proposing a novel opposed-piston free-piston linear generator for use in series hybrid electric vehicles. Secondly, the central combustion chamber is benefit for highly efficient scavenging via intake and exhaust ports without using valves. Click to enlarge.
