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 starting point of engine braking is marked by a vertical green line, and the end point is marked by a vertical red line.

ICCT: real-world NOx from Euro 6 diesel passenger cars more than 2x Euro VI diesel trucks

Green Car Congress

In Europe, the average amount of NO x present in exhaust emissions from modern diesel passenger cars under real-world conditions is more than double the levels from modern trucks and buses, according to a new briefing paper released by the independent research organization International Council on Clean Transportation (ICCT).

Ford now offering dual dry-clutch PowerShift and E85 options for new Focus in Europe

Green Car Congress

liter Duratec Ti-VCT gasoline engine can now be specified with a 6-speed Ford PowerShift automatic transmission with dual dry-clutch technology. Allows the clutches to disengage when the engine is at idle or during deceleration, thus reducing friction and improving fuel economy and NVH. Dual dry-clutch PowerShift. Earlier post.)
