DOE researchers investigate economic and environmental impacts of converting wet waste to renewable diesel

Green Car Congress

Heavy-duty diesel vehicles using mixing controlled compression ignition (MCCI), the most common ignition and combustion strategies for heavy-duty diesel engines, contribute significantly to the emissions of GHG, oxides of nitrogen (NO x ), and particular matter (PM) and are subject to stringent emission standards.

Engine testing shows environmental and performance benefits of hydrotreated vegetable oil as renewable diesel fuel

Green Car Congress

Comparison of power loss and fuel consumption among BD, HVO and iso-HVO. liter diesel engine and passenger car. liter diesel engine and passenger car. On the emissions side, iso-HVO and HVO blended diesel emit less THC and CO than BD, even though iso-HVO blended diesel emits similar level of NO x and PM to blended BD.

Diesel and gasoline prices drop in early 2020, but diesel drops substantially less

Green Car Congress

Although both diesel and gasoline are made from oil, the trends in their prices do not always go in parallel. One reason is that the demands for these two fuels do not necessarily follow each other. 2 diesel and regular gasoline) came from the U.S. by Michael Sivak, Sivak Applied Research. of 1.291).
