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.

Ricardo study finds electric and hybrid cars have a higher carbon footprint during production than conventional vehicles, but still offer a lower footprint over the full life cycle

Green Car Congress

For a battery EV, 46% of its total carbon footprint is generated at the factory, before it has travelled a single mile. The study found that some of the CO 2 savings made during the use of low carbon vehicles is offset by increased emissions created during their production, and to a lesser extent, disposal. Standard gasoline vehicle.

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%.

Environment Canada study finds vehicle exhaust a significant source of isocyanic acid; suggests consideration of new emission standard

Green Car Congress

Researchers at Environment Canada have found that vehicle exhaust is a significant source of isocyanic acid (HNCO), a toxic gaseous acid that is a product of various forms of combustion and a potential health concern. Automobile exhaust is also a known source of inorganic acids such as nitric (HNO 3 ) and nitrous (HONO) acids.
