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. Skaggs et al.

CARB: clean fuels replaced more than 50% of diesel used in California in Q1 2023

Green Car Congress

Clean fuels replaced more than 50% of the diesel used in the state in the first quarter of 2023, according to the California Air Resources Board (CARB). billion gallons of diesel. Since compliance began, the program has helped to replace more than 8.6

Rolls-Royce mtu Kinetic PowerPack approved for renewable diesel

Green Car Congress

Rolls-Royce has approved its mtu Kinetic PowerPacks, based on the mtu Series 4000 and 1600 diesel engines, for use with renewable diesel (HVO/Hydrogenated Vegetable Oil) and the other synthetic diesel fuels of the EN15940 standard. The systems performed the same with HVO as with fossil diesel.

Optimized heavy-duty CI engine fueled with DME delivers diesel performance, significantly reduces engine-out emissions

Green Car Congress

The experimental results showed that DME operation retains the performance on the base diesel engine (338 kW peak power) while significantly reducing the engine-out emissions. Transient operation is unproblematic and very low emissions can be achieved using the same exhaust gas treatment system as for diesel. Soltic et al.

Study on effects of ammonia-diesel blends in CI engines

Green Car Congress

An international team from the Middle East has investigated the characteristics of diesel engines powered by petroleum diesel fuel blended with different volumetric percentages of aqueous ammonia. Since 40%, 50%, and 60% of NH 4 OH have lower heating values than diesel, BSFC is reduced by 7.15, 10.4%, and 15.38%, respectively.

SwRI engineers develop near-zero emissions diesel engine technology; 90% reduction of NOx

Green Car Congress

Southwest Research Institute engineers have developed the next generation of clean diesel engine technology to reduce hazardous nitrogen oxides (NO x ) and carbon dioxide emissions while minimizing fuel consumption. SwRI developed the technology for the California Air Resources Board (CARB). g/hp-hr NO x emissions). and Rao, S.
