T&E: tests show cars powered by electrofuels emit high levels of criteria pollutants

Green Car Congress

E-fuels are made by combining green hydrogen with CO 2 to produce liquid fuel that can be similar to gasoline or diesel used in conventional engines (as well as kerosene used in aviation). The emissions were compared to the standard E10 EU gasoline. However, said T&E, particle pollution was far from eliminated.

MIT team proposes flex-fuel gasoline-alcohol engine PHEV long-haul trucks

Green Car Congress

In a paper being presented at WCX SAE World Congress Experience in Detroit this week, a team from MIT is proposing the use of a flex-fuel gasoline-alcohol engine approach for a series-hybrid powertrain for long-haul Class 8 trucks. We think that the way to enable the use of electricity in these vehicles is with a plug-in hybrid.

UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

The levels of these non-fuel-derived gases will likely remain unchanged, even as more drivers transition from gas-powered to electric vehicles. These emissions are independent of the vehicle energy/propulsion system and therefore applicable to all road vehicle types including those with battery-electric powertrains. Cliff et al.

EEA report: EVs are better for climate and air quality

Green Car Congress

Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. However, the extent to which the GHG emissions advantage is realised during the in-use stage of BEVs depends strongly on the electricity mix.

Mercedes-Benz powering ahead with €3B strategic engine initiative; increasing electrification, 48V; diesel and gasoline; cylinder deactivation

Green Car Congress

There will be world premieres for new advanced technologies, such as the Integrated Starter-Alternator (ISG); the 48 V electrical system; and the electric auxiliary compressor (eZV). The new six-cylinder in-line gasoline engine M 256 features a 48 V electrical system. Systematic electrification: new M 256.

Bosch trialing Neste renewable diesel; aims to offer renewable and synthetic fuels at all company filling stations in Germany

Green Car Congress

Since early November, the cars chauffeuring the management board members of Robert Bosch GmbH have been running on fully renewable diesel. diesel,” this fuel is synthesized mainly from by-products and waste materials. diesel reduces the CO 2 emissions of these cars by around two-thirds, or 65%, from well to wheel. Since C.A.R.E.

City of Boulder working with Fermata Energy to test V2B technology

Green Car Congress

The city and Fermata Energy have installed a charging station that enables two-way electricity: from the building to the car and from the car back to the building. In the pilot, Boulder will connect one of its electric fleet vehicles to the V2B charging system, which also connects to the recreation center’s electricity system.
