A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

Although the pollutant emissions of a diesel engine are less than those of a gasoline one, it still emits carcinogens, nitrous oxides, and soot. To reduce emissions, diesel vehicles use filters that catch exhaust particles and other contaminants. Older models don’t even have the emission-control features that newer ones do. dollars.

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

Green Car Congress

In a recent open-access paper published in ACS’ Environmental Science & Technology , researchers from the University of York report that alcohols in windshield washer fluid account for a larger fraction of real-world vehicle emissions than previous estimates have suggested.

Chalmers study: ban on sales of fossil-fuel cars greatly reduces lifecycle GHG mainly due to tailpipe emissions; risk of carbon leakage in manufacturing

Green Car Congress

If a ban were introduced on the sale of new gasoline and diesel cars, and they were replaced by electric cars, the result would be a significant reduction in lifecycle carbon dioxide emissions primarily due to reduced tailpipe CO 2 emissions, according to a new lifecycle study by researchers at Chalmers University of Technology, Sweden.

Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The exhaust sample was taken from the exhaust manifold. The exhaust sample was taken from the exhaust manifold.

UC Riverside team wins EPA design contest with lawnmower exhaust aftertreatment device

Green Car Congress

A team of University of California, Riverside Bourns College of Engineering students have won an EPA student design contest for developing an exhaust aftertreatment device that cuts CO, NO x and PM emissions from lawnmowers. When tested, the device reduced carbon monoxide (CO) by 87%; NO x by 67% and particulate matter (PM) by 44%.

Birmingham study finds butanol-gasoline blend reduces GDI engine-out carbonaceous emissions; similar NOx

Green Car Congress

A team at the University of Birmingham reports that a blend of 33% v/v of butanol in EN228 commercial gasoline containing 5% of ethanol (B33) reduces GDI (gasoline direct injection) engine-out carbonaceous emissions, while maintaining similar levels of NO x emissions when compared to standard gasoline combustion at low and medium engine loads.
