Swiss team finds particle emissions from aircraft turbine engines at ground-idle induce oxidative stress in bronchial cells

Green Car Congress

In a study on the effect of exhaust particles from aircraft turbine engines on human lung cells, Swiss researchers have found that cells reacted most strongly to particles emitted during ground idling.

WinGD and HSD Engine collaborate to deliver methanol-fueled two-stroke engines

Green Car Congress

The aim is to deliver an engine capable of running on carbon-neutral green methanol by 2024, providing shipowners with a power solution enabling them to meet IMO’s 2050 target—and to reach net-zero emissions—with their next generation of vessels. The Swiss company, Wärtsilä Switzerland Ltd.,

Swiss team concludes that particulate filters should be mandatory for GDI engines

Green Car Congress

In the spring 2014, the GasOMeP project (Gasoline Vehicle Emission Control for Organic, Metallic and Particulate Non-Legislative Pollutants) got underway. The carcinogenic potential in one cubic meter of exhaust gas from gasoline direct injectors is up to 1,700 times higher than the EU limit for clean air. Click to enlarge.

York, Empa study finds retrofitting of VW diesel engines was successful

Green Car Congress

liters displacement (type code EA 189) contained illegal software designed to manipulate emissions. Together with his colleagues, he used a special instrument to examine the exhaust plumes of 23,000 passing cars and analyzed the levels of NO x and CO 2. Here the measured NO x emissions fell by an average of almost 22%.

Empa recommends buying diesel vehicles only if Euro 6d-TEMP or Euro 6d

Green Car Congress

On 1 September 2017, new emissions regulations for passenger vehicles come into force in the EU and Switzerland. These will plug the gaps in the existing legislation and will help to ensure that diesel vehicles in particular become considerably cleaner as regards their NO x emissions. At the end of 2016 around 3.1 Image: Empa.

Study shows two-stroke scooters dominant source of air pollution in many cities; asymmetric polluters

Green Car Congress

A study by European researchers has found that two-stroke (2S) scooters, although constituting a small fraction of the fleet, can dominate urban vehicular pollution through organic aerosol and aromatic emission factors up to thousands of times higher than from other vehicle classes. Emission factors (EFs) from scooters and other vehicles.
