UC Riverside study finds emissions benefits for E15 blend in California

Green Car Congress

A study by a team from UC Riverside has assessed the potential of increasing ethanol content in California reformulated gasoline (CaRFG) by investigating the exhaust emissions from a fleet of 20 Tier 3 light-duty vehicles. Acetaldehyde and ethanol emissions responded strongly with ethanol across the fleet of 20 vehicles.

Study finds GHG emissions from corn ethanol now 46% lower than gasoline

Green Car Congress

A new study by a team from Environmental Health & Engineering (EH&E) has found that greenhouse gas emissions from corn ethanol are 46% lower than those from gasoline—a decrease in emissions from the estimated 39% done by previous modeling. EH&E) and Adjunct Professor of Environmental Health at Harvard’s T.H. —Scully et al.

Study suggests high-mileage light-duty fleets contribute higher emissions and emissions share than expected

Green Car Congress

A study by researchers from the University of Denver and the University of Puget Sound indicates that high-mileage light-duty fleets contribute higher emissions and emissions share than expected based on their actual numbers in the fleet. —Bishop et al. In their study, Bishop et al.

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. US EPA LEVIII).

Ninth annual Green Innovation Index finds California light-duty vehicle emissions spike; major challenge to 2030 climate goals

Green Car Congress

At the same time, per capita emissions in the state decreased by 12%. On an absolute basis, California’s total GHG emissions fell only slightly in 2015, down 0.34% from 2014. This year’s edition finds California’s record is especially impressive when it comes to cutting emissions and energy use per dollar of GDP. Transportation.

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.

Steel LCA study: lightweighting with advanced high-strength steel produces lower GHG emissions than with aluminum

Green Car Congress

The study, “Life Cycle Greenhouse Gas and Energy Study of Automotive Lightweighting,” found that AHSS-intensive vehicles had lower or equivalent life cycle emissions than aluminum-intensive vehicles for every class of vehicles tested: sedans, trucks, SUVs and alternative power train vehicles.
