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. mg kg fuel –1 and were significantly higher than previous biomass burning emission estimates.

An electrically driven compressor for precise exhaust gas recirculation is also used. Then we modify the timing and pressure of the injection, among other things, and look at exhaust emission values and fuel consumption. This is done via exhaust gas recirculation (EGR). —Patrik Soltic.

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

Green Car Congress

Within the scope of an agreement signed in November 2017 ( earlier post ), Eni and FCA have developed “A20”, a new fuel with a low level of emissions due to its 15% methanol and 5% bio-ethanol alcohol content. An initial test run of five Fiat 500s from the Eni Enjoy fleet in Milan ended successfully a few weeks ago.
