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. The FPLG can be used in a small-scale organic Rankine cycle (ORC) system and can directly convert the thermodynamic energy of working fluid into electricity. —Tian et al.

Ford study shows Rankine waste heat recovery system on a light-duty vehicle could almost meet full vehicle accessory load on highway cycle

Green Car Congress

However, in city driving, the ORC system would supply about half of the accessory load requirement for a conventional engine, and only about one-third of the load requirement for a hybrid powertrain, due to the frequent engine off condition, according to the results presented by Quazi Hussain. on the highway cycle and 0.513 on the city cycle.

Study suggests that decarbonizing US transport sector by converting waste CO2 to fuels would require economical air-capture of CO2

Green Car Congress

Kreutz used two examples of CCTF systems in his analysis: biodiesel from microalgae and Sandia National Laboratory’s S2P process (an effort to utilize concentrated solar energy to convert waste CO 2 into synthetic fuels, earlier post ). In CCTF, the source of CO 2 determines the net carbon intensity of the fuel, Kreutz says.

GM details 2016 Chevrolet Malibu Hybrid powertrain design and operation

Green Car Congress

At the 2016 SAE World Congress, GM engineers presented a paper describing the development of the new hybrid powertrain for the popular mid-size sedan. The new engine is fitted with an exhaust gas heat recovery (EGHR) system. The exhaust gas heat recovery unit is attached at the outlet side of the catalytic converter.
