New Emissions Analytics study suggests pollution from tire wear now 1,850 times worse than exhaust emissions

Green Car Congress

In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions ( earlier post ). —Emissions Analytics. Quoting such ratios, however, needs careful interpretation.

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. Older models don’t even have the emission-control features that newer ones do. To reduce emissions, diesel vehicles use filters that catch exhaust particles and other contaminants.

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. An improved version of the device eliminated 93% of particulate matter emissions.
