The Asian monsoon circulation provides an effective pathway for pollution from Asia, India, and Indonesia to enter the global stratosphere, according to a new international study led by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo. NCAR scientist William Randel, the lead author.
They found that the level of emissions of regulated and unregulated pollutants in diesel exhaust depends on fuel, load, engine calibration, and exhaust aftertreatment technology. L/2004 calibration engines. L/2004 calibration engines. Unregulated pollutants also include ozone precursors and bioaccumulative and toxic compounds.
It, or a scaled-up version, could also provide a solution for the Asian motor vehicle fleet, in which two-stroke engine vehicles constitute a major share—and contribute significantly to air pollution. —Faiz and Gautam (2004). International Journal of Vehicle Design , Volume 34, Number 1 doi: 10.1504/IJVD.2004.003891.
China has enormous potential for the expansion of Electric Vehicles as a tool to fight pollution in cities. The racing track record of China Racing, the first international Chinese racing team, speaks for itself and I am convinced they will be a fantastic addition to the competition.
A 2004 lifecycle analysis synthesis report prepared by Five Winds International for ConocoPhillips, Sasol Chevron and Shell International Gas concluded that: Total GHG emissions of the GTL system are between 12% less and 11% more than the refinery system, based on varying assumptions and data. Source: Sasol. Click to enlarge.
The findings, published in the 21 September issue of Atmospheric Chemistry and Physics , are generally consistent with official Chinese government statistics and could bolster their credibility as international negotiations proceed on commitments of China and other nations to combat climate change. Munger, J. McElroy, M.
California’s South Coast Air Quality Management District, the San Joaquin Valley Air Pollution Control District and the Sacramento Metropolitan Air Quality Management District also are investing in the project. liter Opposed-Piston Gasoline Compression Ignition (OPGCI) engine. Earlier post.).
The complaint filed in Manhattan federal court alleges that from approximately 2005 until at least late 2015, Toyota systematically violated Clean Air Act automobile defect reporting requirements designed to protect public health and the environment from harmful air pollutants. Representations to EPA.
In an effort to reliably predict efficiency and pollutant emissions for new engines and fuels, computer simulations are used to study fundamental turbulence-chemistry interactions. Low emission, low temperature engine concepts of the future operate in regimes where combustion is poorly understood. Stochastic processes.
To that end, ARB staff is holding two more workshops on the development of a regulation to limit the amount of time that internal combustion engine-driven TRUs and TRU gensets operate while stationary, as well as requiring an overall zero-emission mode operating time. NO x : 6,100 tons per year. GHG: 770,000 tons per year (CO 2 e).
These systems will also need to deliver very low criteria pollutant levels (e.g., In the longer term internal combustion engines in general start to hit a wall in terms of CO 2 improvement, and ultimately they need a contribution from the fuel side. Gains in new vehicle fleet economy by OEM, 2004-2009. Click to enlarge.
Professor Sybil Seitzinger, Executive Director of the International Geosphere-Biosphere Programme (IGBP). A previous natural ocean acidification event that occurred approximately 55 million years ago at the Paleocene-Eocene Thermal Maximum (PETM) is linked to mass extinctions of some calcareous marine organisms (Zachos et al.,
This partnership was led by EPA’s Design for the Environment (DfE) Program, in the Office of Pollution Prevention and Toxics, and the National Risk Management Research Laboratory, in EPA’s Office of Research and Development. The Abt authors noted that over time, the manufacturing process for SWCNTs will become much more energy-efficient.
Paradox 1 - Soot: There's an apparent emissions paradox with plug-in hybrids (PHEV): Driving longer distances on battery power means more cold starts as the internal combustion engine (ICE) stops and starts up again after the batteries deplete. Cold starts mean more pollution.
For example, in 2004 they posed as representatives of Dow Chemical and promised that the company would clean up after the Bhopal Disaster, leading to a temporary $2 billion drop in the company’s market cap. That includes hybrid EVs, plug-in hybrid EVs, fuel cell EVs and battery EVs.
Dan Hancock, president, DMH Strategic Consulting, retired vice president, GM Powertrain Global Engineering, past president of SAE International, and a member of Achates’ Industry Advisory Board. Argonne National Laboratory has been developing gasoline compression in a series of conventional development engines for nearly 10 years.
But theyve needed definitive proof that PHEVs wont increase pollution. CA, NY, MA and other states have had Zero-Emission Vehicle programs since the early 1990s because battery electric vehicles in those states, taking into account power plants, are far cleaner than gasoline cars in reducing urban air pollution and smog. The GREET 1.6
She outlined a list of complaints: noise pollution (peaks of 87 decibels, well over the allowed 55, according to municipal limits ); streets so packed with revelers that it is hard to walk or even reach one’s front door; an exodus of fed-up locals that is changing the character of picturesque neighborhoods. That was well over the 3.2
Sign the petition Protect the Arctic National Wildlife Refuge www.sierraclub.org/arctic/ American Lung Association call for better EPA air pollution standards. Romm, 2004 "Out of Gas, The End of the Age of Oil", by David Goodstein, 2004 "Hubbert's Peak: The Impending World Oil Shortage", by Kenneth S.
Power and Associates 2004 report ]. Dont PHEVs just shift pollution from gasoline cars to power plants? But its monumentally less pollution , even on the national (half-coal) grid. While other national and international organizations have been supportive at government hearings, they havent yet begun to advocate for PHEVs.
A study conducted before and after the 2004 closure of a coal-burning power plant in Tongliang, China, found that children born before the closure had shorter telomeres than those conceived and born after the plant stopped polluting the air. Results appear in the journal Environment International. —Deliang Tang.
As the next steps in a strategy to cut harmful emissions from ocean-going vessels, the US Environmental Protection Agency is proposing new engine emissions and fuel standards for large marine diesel engines on US-flagged ships that would harmonize with international standards. Earlier post.)
A new working paper by the the International Council on Clean Transportation (ICCT) concludes that tighter heavy-duty diesel vehicle emissions standards in Mexico (NOM 044 standards) would result in a net benefit to Mexico of US$123 billion (1.6
California has made tremendous gains cutting pollution without detrimental economic impacts. But we’re also seeing a significant jump in consumer preference for less-efficient internal combustion engine (ICE) vehicles—even in just the past year in climate-conscious California. Landfill emissions rise; recycling rates decline.
Several dozen prototypes on 15-passenger van since 2004; now in second generation development; no production plans. is likely to unveil a prototype plug-in hybrid at the North American International Auto Show in Detroit as part of its company-wide focus on "electrifying" the car, GM officials said Thursday. Bloomberg ). Reuters ).
The current limit values in Mexico are equivalent to Euro IV or EPA 2004 standards. With it, Mexico joins a very short list of countries (US, Canada, Japan, European Union, and South Korea) with best-in-class, filter-based standards for heavy-duty vehicles, according to the International Council on Clean Transportation (ICCT).
Based on calculations by the International Energy Agency (IEA), 75% of the growth in the world’s energy demand from 2005 to 2030 will come from developing countries. The OPEC Fund for International Development (OPEC Fund). International Finance Corporation; and. International Monetary Fund (IMF) Special Drawing Rights (SDRs).
The research team drew on data from 420 people living near Athens International Airport in Greece, where up to 600 planes take off and land every day. Between 2004-6 and 2013, 71 people were newly diagnosed with high blood pressure and 44 were diagnosed with heart flutter (cardiac arrhythmia). A further 18 had a heart attack.
From an official point of view, COP 15 is to be informed by the most recent report from the UNFCCC’s International Panel on Climate Change (IPCC), the Fourth Assessment Report (AR4), published in 2007. Without a clear and ambitious number, the whole agreement will be in danger ” [ 8 ].
Winner of the 2004 Dale Prize for Excellence in Urban Planning. During the intervening six and half years in the US alone, the auto industry will sell a projected 70-80 million internal combustion engine cars, pointing out the importance of improving today’s technology.
