Porsche simulates hydrogen V8 for virtual Nordschleife run; 440 kW, 261 km/h, near-zero NOx

Green Car Congress

In a recent simulation study reported in Porsche Engineering Magazine , Porsche Engineering examined the potential of hydrogen combustion engines. We have therefore developed a hydrogen combustion engine that aims to match the power and torque of current high-performance gasoline engines as a concept study.

Study finds total PM10 emissions from EVs equal to those of modern ICEVs; role of weight and non-exhaust PM

Green Car Congress

A new study by a team from the University of Edinburgh and independent engineering company INNAS BV has found that, when factoring in the additional weight and non-exhaust PM factors, total PM 10 emissions from electric vehicles (EVs) are equal to those of modern internal combustion engine vehicles (ICEVs).

Study finds ethanol blending appears to reduce significantly genotoxic emissions from gasoline direct injection vehicles

Green Car Congress

A research team from Empa (Swiss Federal Laboratories for Materials Science and Technology) and the University of Applied Sciences Bern, Laboratory for Exhaust Emission Control, reports that ethanol blending appeared to reduce genotoxic emissions from a flex-fuel Euro-5 gasoline direct injection (GDI) vehicle (a Volvo V60 with a 1.6

NC State study finds non-FFV vehicles can adapt to mid-level ethanol blend

Green Car Congress

A study by a team from North Carolina State University, with colleagues from the Urban Air Initiative and 3DATX Corporation, has shown that non-FFVs (flexible-fuel vehicles) can adapt to a mid-level ethanol blend—specifically E27. The study was commissioned by the Urban Air Initiative. — lead researcher Dr. Chis Frey.

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

Green Car Congress

Based on a three-year study of toxic and environmentally relevant pollutants from gasoline direct injection (GDI) engines, Swiss researchers have concluded that some GDI engines emit just as many soot particles as unfiltered diesel cars did in the past. Further, the GDI particles carry numerous carcinogenic substances.

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. —Platt et al.
