Empa and partners exploring DME as fuel with new heavy-duty test engine

Green Car Congress

Over the past few months, we have converted it to DME together with our partner FPT. In addition, the valves and valve seat inserts were converted to materials suitable for DME. An electrically driven compressor for precise exhaust gas recirculation is also used. This is done via exhaust gas recirculation (EGR).

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.

EPA Proposes to Streamline Approval Process for Fuel Conversion Systems

Green Car Congress

The new options would reduce some economic and procedural impediments to clean alternative fuel conversions while maintaining environmental safeguards to ensure that acceptable emission levels from converted vehicles are sustained. EPA expects the streamlined approach to result in a cost savings for many converters. Intermediate age.

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

Green Car Congress

Theoretically, cars operating on higher ethanol blends than the design point could emit greater concentrations of pollutants in exhaust gas. In the cylinder where combustion takes place, the fuel evaporates before it is burned, and this evaporation helps cool off the air/fuel mixture and exhaust gas.

Norway-US Project Developing Diesel/Biodiesel, Cool Flame Reformer and Solid-Acid Fuel Cell APU

Green Car Congress

The reformer converts hydrocarbons into hydrogen, CO 2 and heat. Due to the unit’s high efficiency, CO 2 emissions are substantially lower than in conventional combustion engines, and no other demonstrable exhaust is discharged—i.e., 2001) Solid acids as fuel cell electrolytes.
