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

Green Car Congress

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). Dimethyl ether (DME) can be produced from hydrogen and CO2.

What we don’t admit about carbon dioxide

Electric Auto Association

But before consumers assign appropriate value to low carbon dioxide (CO2) emissions, they must make an accurate judgment about the malevolence of this well-known gas. Unfortunately, our intuitive concepts about CO2 conflict with our scientific appraisal of its harmfulness. Time for a name change?

Europe’s Euro 7 emission limits face pushback from 8 international locations

Baua Electric

8 Ecu Union countries together with France and Italy referred to as for the bloc to scrap deliberate Euro 7 exhaust emission limits, announcing they’re overly determined and unrealistic for automakers to strike. The principles additionally attempt to take on particulates from brakes and tires.

Study finds renewable diesel blends deliver fuel consumption and CO2 benefits in Euro 5 engines

Green Car Congress

HVO based fuels can be used without affecting fuel logistics, engine and exhaust after-treatments. That study showed a clear positive impact of the use of HVO/HCK blends (at different blending ratios) on pollutant emissions. —Napolitano et al.

Tsinghua/Argonne Study Finds That Mass Use of EVs in China Could Result in Higher CO2 and Criteria Pollutant Emissions Than Conventional and Hybrid Gasoline Vehicles Due to Coal-Fired Generation of Electricity

Green Car Congress

The researchers found that while EVs do offer a very promising solution to energy issues due to their replacement of petroleum fuels, for now “ the high pollution levels of coal-fired power plants will trade off EVs’ potential energy benefits in China ”. Gasoline vehicle exhausts contribute very little to total national SO 2 emission (0.2%

ICCT: incremental technology can cut vehicle CO2 by half and increase fuel economy >60% through 2030 with ~5% increase in price

Green Car Congress

Engineering studies and emerging supplier technology developments indicate that costs for lightweighting, direct injection, and cooled exhaust gas recirculation will be reduced by hundreds of dollars, and electric vehicle costs will drop by thousands of dollars per vehicle by 2025. Previous costs of compliance have been greatly overestimated.
