Eni and FCA develop A20: 15% methanol, 5% ethanol high-octane gasoline blend

Green Car Congress

By harnessing its low carbon content, bio component and high octane number (RON 100), the new alternative fuel emits up to 3% less in CO 2 exhaust emissions quantified using the new Worldwide Harmonized Light Vehicle Test Procedures (WLTP).

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. —Norbert Heeb.

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.

University of Wisconsin Researchers Investigating Dual-Fuel (Gasoline and Diesel) Partially Premixed Combustion for High-Efficiency, Ultra-Low Emission Combustion; 53% Thermal Efficiency

Green Car Congress

Researchers at the University of Wisconsin, led by Dr. Rolf Reitz, are investigating a blended dual-fuel (gasoline and diesel) concept to extend the operating range of partially premixed charge compression ignition combustion by using the varying fuel reactivity of the charge blend, which is determined in real time.

ICCT study concludes no technical barriers to use of higher blends of ethanol

Green Car Congress

Pressure on the RFS2 has increased as statutory mandated volumes of biofuel exceed the “blendwall” of 10% ethanol in gasoline. Ethanol has about one-third lower energy density than gasoline; accordingly, cars drive fewer miles per gallon when operating on ethanol blends compared with unblended gasoline. The ICCT ethanol paper.

Opel introducing new CNG Zafira Tourer with 329-mile natural gas range, lower fuel consumption

Green Car Congress

Like the previous model, the Zafira Tourer features Opel’s monovalentPlus system and has a 14-liter gasoline reserve, giving it an extra 150 km (93 miles) of range. This reduces harmful emissions, leading in turn to cleaner exhaust gases. For example, in Germany CNG is 50% less expensive than gasoline. The Zafira Tourer 1.6

EPA Proposes to Streamline Approval Process for Fuel Conversion Systems

Green Car Congress

Conversion systems allow vehicles to run on alternative fuels; most conversions involve switching gasoline or diesel vehicles to operate instead on a gaseous fuel such as natural gas or propane; an alcohol fuel; or electricity.
