Researchers developing free-piston linear generator for exhaust waste heat recovery

Green Car Congress

Researchers in China have developed a novel free-piston linear generator (FPLG) to recover exhaust waste heat efficiently from a vehicle engine. reports that the energy conversion efficiency of the FPLG can reach up to 45.82% with an intake pressure of 2.6 The piston is connected with linear generator mover by a connecting rod.

Fraunhofer developing process to ferment steel exhaust gases to fuels and chemicals

Green Car Congress

Fraunhofer researchers in Germany have developed a process for the conversion of CO-rich exhaust gases from steel plants into fuels and specialty chemicals. In addition to the exhaust gases, syngas—similar gas mixtures from home and industrial waste incineration—can also be used for the engineered process.

SwRI D-EGR gasoline demo vehicle delivers diesel efficiency at lower cost; potential for LEV III/Tier 3 emissions

Green Car Congress

Southwest Research Institute (SwRI) announced preliminary test results of its Dedicated-Exhaust Gas Recirculation (D-EGR) demonstration vehicle ( earlier post ) at the SAE 2014 World Congress in Detroit. With D-EGR, one or more cylinders have their exhaust connected directly to the intake system. The engine conversion.

Exhaust gas values were also greatly improved by the use of electrofuels. Since the tests of engine efficiency and exhaust gas values of all sources reviewed were conducted in test engines that had not been optimized for the used fuel, further potentials regarding emission reduction and the optimization of engine efficiency are expected.

The piston and crankshaft are connected by means of the upper and lower links. The lower link is also connected, via the control link, to the center of the eccentric journal of the control shaft. Conversely, moving the center of the eccentric journal downward raises the compression ratio. Hiyoshi et al. 2006) Click to enlarge.
