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. features in developing the standards. NHTSA and CAFE.
This means that in addition the power demand is more difficult to achieve with engine downsizing and transmission down-speeding alone. The EU goal is to introduce the WLTP by 2017 if possible and no later than 2020 to coincide with the 95 g/km requirement. The WLTP is significantly more dynamic with faster acceleration rates.
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.
Working with its technology partner Hubbard Products ( earlier post ), the entire refrigeration system has also been reconfigured, downsizing a number of components and optimizing them to deliver maximum efficiency and higher levels of performance. The only emission back to the atmosphere is air or nitrogen.
This has resulted in higher catalyst loading per volume of substrate and led to downsizing of systems from those available in 2010. New substrates are designed with thinner walls or higher porosity, which allows the coating of better catalysts without sacrificing durability.
The selected projects will focus on reducing the total cost of ownership of NGVs, increasing vehicle efficiency, decreasing local air pollution, and advancing technology development to increase the use of more affordable medium- and heavy-duty natural gas engines and vehicles.
This has not raised any issues for criteria pollutants, as upstream emissions associated with production and distribution of the fuel are addressed by comprehensive regulatory programs focused on the upstream sources of those emissions.
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.

Expand credits for fleet downsizing, adding cleaner vehicles ahead of any regulatory requirements, and for installation of early retrofits. forklifts). Ease annual requirements to clean up engines (e.g.,
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. We hope Ford will, and then move ahead!
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.
It’s a none-too-subtle form of propaganda on behalf of the most polluting, planet-warming product anyone sells and uses in our world. It looks to me to be a combination of being emasculated by eight years of Bush/Cheney as well as the paper’s own decade of internal decline, downsizing and dumbing down.
In fact, the optimized PHEV is much more efficient as a long range liquid fuel vehicle, because the engine is downsized. In addition, the second car will likely be a conventional car burning more fuel and creating more CO 2 per distance traveled than a long range PHEV because of the greatly downsized and more efficient engine in the PHEV.
