UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

There are widespread policy assumptions that the phase-out of gasoline and diesel internal combustion engines will over time lead to much reduced emissions of Volatile Organic Compounds (VOCs) from road transport and related fuels. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g.,

NREL study probes emissions impact of butanol-gasoline blends in light-duty vehicles

Green Car Congress

Results of a study led by a team from the National Renewable Energy Laboratory on the impact of butanol-gasoline blends on light-duty vehicle emissions suggest that widespread deployment of n-butanol or i-butanol in the gasoline pool could result in changes to the estimated emissions of alcohols and carbonyls in the emissions inventory.

UAI and EFC call EPA MOVES2014 emissions model treatment of ethanol “seriously flawed”; call for peer review

Green Car Congress

MOVES2014 is the latest version of MOVES and includes the effects of the Tier 3 rule as well the impacts of other EPA rulemakings promulgated since the last MOVES release in 2010; new emissions data; and new features that users have requested. EPA has advised states to use MOVES2014 in SIP development as expeditiously as possible.

Ford, GM and AVL researchers argue match-blending a flawed approach to evaluate ethanol-gasoline blends

Green Car Congress

In a newly published SAE paper, a team from Ford, General Motors and AVL argues that the exclusive use of a match blending approach to prepare ethanol-gasoline blends for regulatory emissions testing “has fundamental flaws”. Earlier post.). —Anderson et al.

New Toyota Highlander turbocharged engine offers more torque and fewer emissions

Green Car Congress

Fuel efficiency is also improved for this higher-torque engine with an EPA-estimate of up to 25 MPG combined. The new engine, standard across all gasoline grades, is also more environmentally conscious, with more than a 50% reduction in NO x and NMOG compared to the outgoing V6 engine. liter V6 engine’s 263 lb-ft (357 N·m).

UC Riverside team examines influence of mid-and high-level ethanol blends on pollution from GDI flex fuel vehicle

Green Car Congress

Their paper is published in the ACS journal Energy & Fuels. The researchers used four fuels: a baseline US EPA Tier 3 E10 fuel; one E10 fuel with higher aromatics content than the baseline E10; an E30 fuel that was splash-blended with the Tier 3 E10; and an E78 fuel. Data presented as mean ± standard deviation, N=3. Yang et al.
