The US Environmental Protection Agency (EPA) and the US Department of Transportation (DOT) formally unveiled their joint proposal to set stronger fuel economy and greenhouse gas pollution standards for Model Year 2017-2025 passenger cars and light trucks. L/100km), if the vehicles were to meet this CO 2 level all through fuel economy.
Ford views EcoBoost as a strategy as well as a product—one that will serve as a key element of Ford’s CO 2 and fuel economy product strategy—said Dan Kapp, Director, Ford Powertrain Research and Advanced Engineering, during a briefing on the company’s fuel economy strategies in Dearborn. Planning background.
The engine should yield fuel efficiency gains of more than 50% compared to a downsized, turbo-charged gasoline direct injection engine, while reducing the overall cost of the powertrain system, said Fabien Redon, Vice President, Technology Development at Achates Power. Earlier post.) Fabien Redon.
The Automaker Rankings report examines the emissions of both global warming and smog-forming pollution from of the automakers. To determine GHG emissions, UCS considered the fuel economy, fuel type, and sales volume of each type of vehicle sold by each automaker in the 2013 model year (MY2013). Source: UCS. Click to enlarge.
Current fuel economy policy clearly demonstrates this fact. —“The Case for Technology Neutral Public Policy in Fuel Economy Debate”. The quickest and most cost-effective way to achieve our energy usage goals is through faster adoption of fuel-efficient downsized gasoline and diesel engines.
Pollutant emissions are likewise reduced through combustion control. Applied to a turbocharged, downsized engine, MultiAir can contribute to up to a 25% reduction in fuel consumption over conventional naturally aspirated engines with the same performance, according to Fiat.
Gasoline direct-injection (GDI) engines have higher fuel economy compared to the more widely used port fuel injection (PFI) engines. Recent studies have compared emissions of PFI and GDI vehicles, including particle number and mass, gaseous pollutants, and nonmethane organic gas (NMOG) composition for a limited number of compounds.
Based on test work already carried out, Ricardo estimates that a fuel economy improvement of up to 30% is possible with no loss of power or performance, using a downsized EBDI engine in place of currently available gasoline powertrain technology. fuel economy improvement. liter EBDI engine—resulting in up to a 16.8%
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.
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., What more is need to end urban pollution, something we’ve been spending over 30 years working on? smog and particulates. We heard a little bit from Tom Cackette yesterday about LEV III.I
Yesterday, the US Environmental Protection Agency (EPA) and the National High Traffic Safety Administration (NHTSA) jointly established increasingly stringent greenhouse gas emission standards under the Clean Air Act for 2012 through 2016 model-year vehicles and fuel economy standards under the Corporate Average Fuel Economy program, respectively.
define complementary measures controlling vehicle pollutant emissions in use, based on a thorough analysis, with the aim of delivering a timely reduction of real-world pollutant emissions, hence, contributing to improved air quality. By 2020, 70% of new growth will be in the emerging economies. Background information.
With President Obama and the rest of the leaders of the world’s biggest polluting nations kicking the ball down the field on climate change and effectively pulling the rug out from under all of us who have been targeting the Copenhagen climate talks as the moment we must seize, our response must recognize the obvious.
To achieve these results, PureTech development called for a number of changes, chief among which were: Downsizing. Top speed is up 7 mph (11 km/h), and fuel economy is also improved by up to 1.5 The specifications also stipulated a specific power of 50 kW per liter. Three cylinders. liter unit it replaces. l/100km (52.3
Renault’s ongoing downsizing strategy is aimed at reducing the cubic capacity of its engines in order to bring down fuel consumption and CO 2 emissions, without detracting from performance. The downsizing process involved shortening the piston stroke by reducing the size of the crank pin and conrod assembly. Select Engines.
Such a standard will be necessary for the global automotive industry to achieve the economies of scale demanded by original equipment manufacturers. This means that in addition the power demand is more difficult to achieve with engine downsizing and transmission down-speeding alone.
This has resulted in higher catalyst loading per volume of substrate and led to downsizing of systems from those available in 2010. A wide variety of technology options can be deployed on heavy-duty engines and vehicles to reduce engine-out NO x while improving fuel economy to reduce the total cost of ownership of trucks.
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. They assumed a baseline fuel economy of 21.4 They assumed a baseline fuel economy of 21.4 Click to enlarge.
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. It is a safe fuel. The toxicity (mortality) is comparable to or better than gasoline. Earlier post.).
By rightsizing engines with available technologies, automakers are able to continue applying the benefits of smaller turbocharged engines while fine-tuning powertrain systems to further optimize fuel economy, emissions and performance. E-boosting products can significantly improve engine responsiveness and also provide better fuel economy.
The analysis used by federal agencies to set standards for fuel economy (CAFE) and greenhouse gas emissions for new US light-duty vehicles from 2017 to 2025 was thorough and of high caliber overall, according to a new report from the National Research Council. UMTRI Survey: US drivers want better fuel economy, don’t care how.
The engine is undergoing a significant evolution of its own, as new fuel economy and emissions standards in the light-duty and heavy-duty sectors push the development of new technologies on an unprecedented scale toward the theoretical limits of engine operation. That is not to say that things will stay as they are now.
Groundbreaking research in the last 10 years has identified combustion engine strategies that—especially if optimized to run on new fuels—would offer significantly higher efficiency and produce fewer engine-out pollutants than current engines. Fuel research will focus on low-GHG advanced biofuel/petroleum blends.
Essential to this is the recognition that current fuels available in the marketplace constrain engine efficiency and limit the potential fuel economy and greenhouse gas improvements available across the light, medium, and heavy duty transportation fleet. High dilution may also lead to controllability challenges.
The objections they raised for years -- "no one is interested, no one would plug in, the technology is too complex, the benefits are minimal, its just shifting the pollution from the tailpipe to the smokestack, theres no demand for these cars" -- still show up occasionally, but are by and large history. Red Herring ).
ARB staff proposed amendments to the Truck and Bus regulation and Off-Road regulation to provide relied to fleets adversely affected by the economy, and to take into account the fact that emissions are now lower than previously predicted. forklifts). Ease annual requirements to clean up engines (e.g., Port Truck Regulation.
The changes to the regulation implement legislation signed by Governor Arnold Schwarzenegger in February to provide temporary relief to firms that have reduced used of their vehicles due to downsizing or work stoppage. The changes will not repeal or delay general implementation of the rule. ARB Chairwoman Mary D.
Frank has spent more than 30 years in breakthrough vehicle development, during which he received two world records for vehicle fuel economy, designed nine generations of PHEVs, and was a four-time winner of US DOE Advanced Vehicle Design competitions. The PHEV provides the advantage in all these criteria.
The Corporate Average Fuel Economy (CAFE) program, implemented under President Barack Obama in 2012, called for annual increases of 5% to the average fuel economy of new vehicles through the 2025 model year. In 2019, fuel economy actually worsened, dropping slightly from 25.1 percent and extending the standards through 2026.
