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. GLE and $0.9/GLE.

JATO: European new car CO2 emissions highest average since 2014; shift from diesel to gasoline and SUVs rise

Green Car Congress

The analysis covered 23 markets in Europe and found a direct correlation between diesel car registrations and average CO2 emissions. With increased negative public perception towards diesels, combined with new government regulations such as WLTP and scrutiny of the fuel type, demand for diesel fell by 18% in 2018.

JATO: new car CO2 emissions rise for the first time in a decade in Europe; diesel down, gasoline up, SUVs up

Green Car Congress

This rise in average CO 2 emissions correlates with a decrease in demand for diesel cars across Europe—which produce lower CO 2 emissions than gasoline cars—and the rising popularity of SUVs, which emit higher average CO 2 emissions of 133.0 In turn, diesel cars accounted for just 43.8% g/km—a difference of 5.5

EU-funded project develops diesel engine for light helicopters

Green Car Congress

EU-funded scientists developed a novel 320 kW (429 hp) diesel engine for light helicopters as an alternative to conventional turboshaft engines. The technology demonstrated substantial reductions in fuel consumption and emissions. The engine weight is the crux of the project. —DELILAH final report.

Diesel/2-methylfuran blends show higher brake thermal efficiency, higher NOx than diesel

Green Car Congress

Researchers at Wuhan University report on the first comprehensive study of the combustion and emissions performance of blends of diesel and the renewable fuel 2-methylfuran (MF) in compression-ignition engines. Their paper is published in the journal Fuel. —Xiao et al. MPa, respectively. MPa, respectively. Above 0.38

Swiss WTW study finds important role for alternative fuels as well as alt drivetrains in move to low-emissions vehicles

Green Car Congress

Third, the analysis offers a novel comparison of drivetrain and energy carrier production pathways based on natural resource categories. Included in the analysis are fuel cell, electric, hybrid-electric and conventional ICE drivetrains; energy carriers include gasoline, diesel, CNG, biogas, hydrogen and electricity.

Argonne study finds BEVs can have lowest scheduled maintenance costs, but highest cost of driving

Green Car Congress

The study considers five different powertrains (internal combustion engine, hybrid-electric, plug-in hybrid-electric, fuel-cell-electric, and battery-electric) and 12 cost components (purchase cost, depreciation, financing, fuel, insurance, maintenance, repair, taxes, registration fees, tolls and parking, payload capacity and labor).
