EPAs GHG Standards for Light-Duty Vehicles; Special Credits To Encourage PHEVs, BEVs and FCVs

Green Car Congress

Light trucks. This approach would allow credit trading among all vehicles a manufacturer produces, both cars and light trucks, as well as between companies. Eligible innovative technologies include those that are used in one or more current vehicle models, but that are not yet in widespread use in the light-duty fleet.

Study finds catalyzed gasoline particulate filters effective at reducing particulate and PAH emissions from GDI engines

Green Car Congress

The researchers assessed the gaseous, particulate, and genotoxic pollutants from two current technology gasoline direct injection vehicles when tested in their original configuration and with a catalyzed gasoline particulate filter (GPF). liter downsized turbocharged centrally-mounted direct injection engine. —Yang et al.

DOE BETO seeking input on Optima initiative for co-optimization of fuels and engines

Green Car Congress

The initiative intends to accelerate the widespread deployment of significantly improved fuels and vehicles (passenger to light truck to heavy duty commercial vehicles) by 2030. The “Optima” program bridges the broad expertise and resources of the Vehicle Technologies Office and the Bioenergy Technologies Office at the DOE.

Advanced Turbocharged, Direct Injected Gasoline Engines Poised to Take on Diesels in US and in Europe for Reduced Fuel Consumption and Emissions

Green Car Congress

Additionally, suggested one of the speakers, advanced SIDI (spark-ignited, direct-injection) engines can take light-duty market share back from diesels in Europe based on the same trends. However, prior to the remarks on climate change and the regulatory response, he spent a few minutes discussing the efforts on urban pollution—e.g.,

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

Due to the continued exposure of millions of Americans to poor air quality, both the United States Environmental Protection Agency (EPA) and California Air Resources Board (CARB) have announced rulemakings focused on revising the heavy-duty truck emission standards, with a particular focus on tighter limits for oxides of nitrogen (NO x ).

U Toronto team assess the climate trade-off between reduced CO2 and increased Black Carbon from GDI engines

Green Car Congress

The upside of gasoline direct injection (GDI) engines is widely seen as being improved fuel economy coupled with an increase in specific power (especially with turbocharging), enabling significant downsizing. l/100 km)—the average fuel economy of the in-use United States light-duty fleet in 2014.

Taking another look at methanol as an alternative transportation fuel for the US

Green Car Congress

It is a high octane fuel with combustion characteristics that allow engines specifically designed for methanol fuel to match the best efficiencies of diesels while meeting current pollutant emission regulations. Resources. It is a safe fuel. The toxicity (mortality) is comparable to or better than gasoline. —Bromberg and Cheng.
