US Tire Manufacturers Association to produce standardized tire tread particles for researchers

Green Car Congress

In 2020, independent global emissions testing company Emissions Analytics reported that pollution from tire wear can be 1,000 times worse than what comes out of a car’s exhaust. The Tire Industry Project created this methodology to support research on tire wear by providing a reliable and affordable material for lab experiments.

Research consortium investigating use of DME blends in diesels with minimal retrofitting

Green Car Congress

Previous studies have shown that it is possible to operate diesel engines with 100% DME, but that this requires significant effort (injection components, combustion process, exhaust gas aftertreatment, tank system) in terms of conversion.

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.

International automotive researchers emphasize the importance of continued development of the internal combustion engine

Green Car Congress

the pollutant emissions discharged at the tailpipe outlet will be so low as to be hardly measurable, and their practical impact on air quality will be negligible. Further development of exhaust gas energy recovery systems with turbo-compounding and possibly chemical reforming should be encouraged. —Reitz et al. g/bhp-h or 15–20?mg/km).
