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

Audi testing find e-ethanol and e-diesel produced by Joule often perform better than conventional counterparts

Green Car Congress

Audi testing of synthetic ethanol (Audi e-ethanol = Joule Sunflow-E) and synthetic diesel (Audi e-diesel = Joule Sunflow-D), produced in partnership with Joule ( earlier post ) in a pressure chamber and optical research engine has shown that the Audi e-fuels often perform better than their conventional counterparts.

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.

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

Natural gas does not offer climate benefits compared to gasoline and diesel, and many biofuel pathways do not, either. —“A global comparison of the life-cycle greenhouse gas emissions of combustion engine and electric passenger cars”. Life-cycle GHG emissions for global typical medium-size passenger cars registered in 2030.

Cavitation Technologies Announces Results of Water-Diesel Emulsion Initial Testing

Green Car Congress

(CTI) new HydroFuel water-diesel blend indicates that using 10-20% water-in-oil emulsion (diesel) allows the reduction of fuel consumption by up to 12% and reduces the emission of NO x by 40%, and that of sulfur dioxide and hydrogen sulfide by 50%.

Ricardo demonstrates processes for evaluating light-duty diesel emissions under coming Real Driving Emissions (RDE) regs

Green Car Congress

Despite the continuing and significant reductions in the legislated limits of light-duty diesel vehicle NO x emissions under the European Euro 1 through 5 regulations of recent years, many studies have demonstrated that real-world NO x emissions appear not to have been reduced as significantly.

Sandia team develops autoignition model designed for efficient, accurate engine simulations

Green Car Congress

Researchers at Sandia National Laboratories have developed a model for how diesel engines autoignite. Developing an improved understanding of transient mixing and combustion processes inherent in diesel injection is an important element in the design of advanced engines. This is where our chemical model has proven its usefulness.
