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 two cylinders are alternately in the intake-expansion stroke and exhaust stroke. In a paper published in the journal Applied Thermal Engineering , the team from. Prototype FPLG.

Study finds PM from biodiesel blends may be 50-80% less toxic per unit PM mass than from petroleum diesel

Green Car Congress

In the study, the team examined the relationships between biodiesel fuel blend, exhaust particle oxidative potential (OP), and PM composition. OP in oxidized aerosols, including engine exhaust, is commonly quantified using the DTT (dithiothreitol) assay. PM-normalized DTT Activity for biodiesel exhaust PM. —Holmén et al.
