D-EGR is an engine and control concept that combines fuel reforming to produce hydrogen with high levels of exhaust gas recirculation (EGR) to achieve very high levels of thermal efficiency. PSA has been a member of the HEDGE consortium (now at HEDGE-III ) since 2004. In 2013, SwRI reported a 2.0-liter

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. Redon presented the basics of the OP4 engine concept at the SAE High Efficiency IC Engine Symposium in Detroit. Click to enlarge. Click to enlarge.

The remaining two-thirds are lost as waste heat going into the environment through the car’s exhaust emissions and through the radiator. Making some of that waste heat energy available through intelligent heat management offers significant potential for reducing fuel consumption and CO 2 emissions, BMW said.

In a poster-session paper presented at CIMAC Congress 2016 in Finland, Ricardo described the use of this split-cycle concept in high- and medium-speed engines for power generation to achieve efficiencies of 60% from units of 1–30 MW mechanical output. The benefits of a split cycle have been demonstrated numerous times by different bodies.

The high efficiency of the Porsche 919 Hybrid is the result of a balanced overall concept. The first system is the innovative recovery of thermal energy by an electric generator powered by exhaust gases. Efficient use of available power helps to achieve an optimal lap time. gallons of fuel available. Click to enlarge.

two split pairs) operating in a 2004 Chevrolet Cavalier would consume 25% less fuel under the FTP (Federal Test Procedure) than the comparable standard gasoline engine, while matching power and torque. A naturally aspirated Scuderi Air-Hybrid configuration consumes 30-36% less fuel under similar drive conditions, the simulations found.
