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.

Study shows renewable diesel from crude tall oil is a high quality drop-in fuel for off-road engines

Green Car Congress

A team from the University of Vaasa (Finland) and UPM-Kymmene Corporation has examined how the blends of fossil and renewable diesel produced from crude tall oil (CTO) affect the performance and exhaust emissions of the modern common-rail off-road diesel engine. No engine or parameter modifications were made.

Study finds Neste renewable diesel significantly reduces PM emissions in off-road mobile machinery; lower number and mass

Green Car Congress

A study led by researchers at Tampere University of Technology in Finland found that the use of neat Neste MY Renewable Diesel in working machines—a Wille 355B compact utility machine and Wille 855C multi-purpose wheel-loader—efficiently reduces particulate matter emissions compared to EN590 diesel with 7% biodiesel.

Study finds particulates from auxiliary vehicle heaters can be up to 1000 times higher than from idling gasoline engines

Green Car Congress

Researchers from Tampere University and the University of Eastern Finland have found that the particulate emissions of auxiliary heaters can be up to a thousand times higher than the particulate emissions of idling gasoline vehicles. Their open-access study is published in the journal Atmosphere. doi: 10.3390/atmos12091105.

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.)

Neste files patent on gasoline fuels with high bioenergy content

Green Car Congress

The resulting fuels with high bioenergy content can be used in conventional gasoline-fueled automotive engines. from VTT Technical Research Centre in Finland and Neste showed that a combination of ethanol or isobutanol with bio-hydrocarbon components offers an option to reach high gasoline bioenergy content for E10-compatible cars.
