Towards an ecological culture for the automobile industry: a case study from China
This paper explores the nature of the ecological culture for the auto industry and the protection of the environment using China as a case study example. From the study, a comparative analysis showed that 75% of state-owned auto enterprises met the Euro III emission standards, while 67% of non-state-owned auto enterprises reached the Euro IV emission standards. It was recommended that this gap ...

Ultra Low Emission Vehicle II Ultra Low PGM
The task for the emissions management sector is to deliver cost effective solutions to meet future emissions standards. Global Emissions Management reports on catalyst development at Johnson Matthey demonstrating that ULEV II limits can be met using advanced palladium-rhodium three-way catalyst (TWC) technology at ultra low platinum group metal (PGM) loadings. To view the full article ...

International Trade and the Environment: Theoretical and Policy Linkages
I review and extend three approaches to trade and environmental policies: competitive general equilibrium, oligopoly and monopolistic competition. The first two have surprisingly similar implications: deviations from first-best rules are justified only by constraints on policy choice (which motivates what I call a “single dividend” approach to environmental policy), and taxes and emissions ...

Required changes in emission standards for high-frequency noise in power systems
This paper discusses some recent developments that make the existing standards on the emission of high-frequency noise in power systems need to be reconsidered. It is shown that it is possible for an equipment to remain below the emission limits while at the same time the disturbance level increases beyond what was intended by the standard document. Further, the change from analog to digital ...

Cubic-Ruiyi Made Great Technical Breakthrough in High-End Automobile Emission Testing Equipment Before National VI Comes
If you go to buy a car or inspect a car, you often hear the national VI standard, car sales will also tell you to try to buy a car in line with the national VI B model. You may be wondering: what are the VI A and VI B? What kind of standards and testing equipment are used to detect the national VI B? With the coming of National VI B, is there any Chinese test equipment that can support the test ...

Risk Assessment: Refinery MACT 1 and 2
Section 112(f)(2) of the Clean Air Act (CAA) requires the U.S. EPA to determine for source categories subject to Maximum Achievable Control Technology (MACT) standards whether the emission standards provide an ample margin of safety to protect public health. This assessment is carried out by the U.S. EPA in a two-step process that includes the primary objective of developing regulations to ...

Removal of chromium(III) from aqueous waste solution by liquid–liquid extraction in a circular microchannel
A new circular microchannel device has been proposed for the removal of chromium(III) from aqueous waste solution by using kerosene as a diluent and (2-ethylhexyl) 2-ethylhexyl phosphonate as an extractant. The proposed device has several advantages such as a flexible and easily adaptable design, easy maintenance, and cheap setup without the requirement of microfabrication. To study the ...

Facing the New Emission Standards for Hydrochloric Acid Pickling
The U.S. Environmental Protection Agency (EPA) has developed a new regulation to reduce hazardous air pollutant (HAP) emissions from facilities that pickle carbon steel using hydrochloric acid (HCl) solution as well as from associated HCl regeneration plants. This regulation, the National Emission Standards for Hazardous Air Pollutants for Steel Pickling – HCl Process Facilities and HCl Acid ...

A brief history of technology-forcing motor vehicle regulations
Faced with the worst air quality in the United States, California began in the 1960s to pursue a “technology-forcing” approach in establishing motor vehicle tailpipe emission standards. This approach sought to advance vehicle pollution control technology by establishing future tailpipe emission limits even if no technologies existed to meet them at the time regulators set the standards. The U.S. ...

Advice on choosing 2010 compatible specs for heavy haulers
Heavy haulers that transport loads above 120,000 pounds gross combination weight (GCW) must carefully specify their trucks for both durability and power. An over-spec’d truck may reduce fuel mileage and increase acquisition costs, while an under spec’d truck may not be sufficient to move the load, or may increase maintenance costs. The challenge is to achieve the right balance between ...

Indoor Cats Improve Quality of Exhaust Emissions
For over two decades, the automotive industry has struggled to keep up with emission standards by installing emission control systems that are increasingly more sophisticated and expensive. In the meantime, emission control for materials handling equipment has not been a major concern. Without having to meet stringent tailpipe emission standards and faced with pressures to contain costs, OEMs of ...

New Non-Road Regulations in USA and Europe
Earlier this year, the United States Environmental Protection Agency (EPA) introduced Tier 4 emissions standards for diesel engines in non-road mobile machinery (NRMM), which will come into force between 2008 and 2015.The European Union (EU) has also published its own, equivalent rules. Although the two sets of regulations are structured very differently, the effect is the same: a 90% ...

Defeat Devices Could Cost Volkswagen $18 billion
Can you cheat compliance? Volkswagen AG, Audi AG, and Volkswagen Group of America, Inc. (Volkswagen) recently discovered that the answer is “no.” On September 18, 2015, the U.S. Environmental Protection Agency (EPA) issued a Notice of Violation (NOV) of the federal Clean Air Act (CAA) to Volkswagen after discovering diesel cars from model years 2009 to 2015 contain software that ...

Partial or full bag replacement: Truth versus fallacy
Replacing filter bags on demand may seem like a convenient way of managing maintenance costs. But waiting to replace bags at the point of failure, or just before, can lead to a greater risk of non-compliance with emissions standards, higher costs, and higher overall emissions levels. So why are some cement producers opting for partial replacement over full? With cement plants working around the ...
