Study finds modern diesel cars emit fewer carbonaceous particulates than gasoline cars
A new study by an international team led by researchers from the Paul Scherrer Institute (PSI) in Switzerland has found that modern diesel passenger cars equipped with diesel particulate filters (DPFs) emit fewer carbonaceous particulates than gasoline-powered vehicles. The open-access study is published in the journal Scientific Reports.

They found that emissions from new gasoline cars (both EU and US) produce up to 6.5 times more SOA than POA after 5–10 hours of atmospheric aging. New diesel cars produced no detectable SOA, contrasting with old diesels, for which SOA production is about equal to emitted POA.
