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. Prototype FPLG.

New composite reduces rare earth element usage in three-way catalytic converters

Green Car Congress

The high-performance, three-way catalytic (TWC) converter is one of the workhorses of emissions reduction for gasoline engines. This function is crucial in current TWC, in which the oxygen partial pressure in the exhaust must be regulated to be near the ideal air-to-fule ration (A/F = 14.6).

Study finds “markedly” high levels of diesel exhaust present in commuter trains powered by locomotives in pull-mode

Green Car Congress

Diesel-powered commuter trains may expose their passengers to elevated levels of certain black carbon and ultrafine particles, especially in the coach directly behind the locomotive, according to a new study from researchers at the University of Toronto. A paper on the study is published in the journal Atmospheric Environment. 2017.02.015.

Mærsk, Wallenius Wilhelmsen, BMW Group and others partner to explore blend of lignin and ethanol for sustainable shipping fuel

Green Car Congress

Mærsk and Wallenius Wilhelmsen have teamed up with the University of Copenhagen and major customers including BMW Group, H&M Group, Levi Strauss & Co. While bioethanol is not a drop-in fuel, the residual lignin can be converted to a drop-in fuel via thermal treatments such as gasification or solvolysis. Nielsen, Anders Jensen, Line R.
