  • Bad air at home linked to poor performance at school

    EPA Warns Indoor Air More Concerning  That polluted haze that can be seen over the horizon, acting like a beacon and reminding you what should already be common sense and well understood: dirty air is not good for your health. That is the visible simplicity of smog outside, but how about the air in your own homes or where you work? ...

  • Real-world vehicle emissions as measured by in situ analysis of exhaust plumes

    Abstract We conducted a 60-day roadside measurement campaign on a busy street in Münster, Germany, during summer 2016. We used gas and particle concentration measurements with high temporal resolution (10 Hz) to quantify both the emission ratios of nitrogen oxides per carbon dioxide (NOx/CO2) for over 70,000 individual exhaust plumes as well as the emission ratios ...

  • Process-generated contaminants

    Overview: There is not currently a formal and universally recognised definition of a process-generated substance. Process-generated contaminants can be generated as emissions from combustion processes, abrasion and/or other processes that physically or chemically degrade or otherwise modify the starting material(s), e.g. degradation/composting of organic materials. Such ...

  • Effect of turbulence intensity on PM emission of heavy duty diesel trucks – Wind tunnel studies

    Abstract Stringent emission regulations have forced drastic technological improvements in diesel aftertreatment systems, particularly in reducing Particulate Matter (PM) emissions. The formation and evolution of PM from modern engines are more sensitive to overall changes in the dilution process, such as rapidity of mixing, background PM present in the air. These technological ...

  • Fuel Homogenization

    The structure of the financial expenses of automotive businesses and boiler plants is quite varied, though it still allows to identify the main expenditures. First of all, it is the fuel, which accounts for no less than 40% of all costs. Fuel homogenization devices are designed to increase the quality of combustion, thereby saving resources. Homogenized fuel features good performance, ...

  • Designing A Better Alternative for Post-Closure Care

    After a landfill has reached the end of its service phase, federal law requires owners to install a final soil cover and maintain it over the next 30 years. This is the traditional strategy that most landfill owners employ and represents a significant cost of business. When all the layers are tallied together, the capping and post-closure period can cost up to $400,000 for a small, 100-acre ...

  • BBA Pumps introduces a new concept for high pressure high head and mining pumps

    BBA Pumps has made great strides in recent years in the development of clean and super silent mobile pump sets. This is driven in part by the stringent US EPA and European emissions legislations, whereby diesel-powered equipment in Europe must comply with the Stage V / Tier 4 requirement from 2019. Other continents, in which environmentally sustainable solutions were traditionally of lower ...

  • Dual fuel turbocharged engine operated with exhaust gas recirculation

    Abstract With good combustion characteristics, hydrogen has been developing as a clean alternative fuel of engines. This study is to develop a diesel/hydrogen dual fuel engine. The hydrogen was added at inlet port in a 4-cylinder direct injection turbocharged diesel engine with an EGR (Exhaust Gas Recirculation) system to investigate engine performance and exhaust pollutant. The ...

  • Change Is On the Horizon

    Late last year, the U.S. Department of Energy (DoE) enacted the Energy Conservation Standard for Pumps for all domestic pumps. The first of their kind for the pump market, these standards set the minimum efficiency for a given pump model and will lead to a significant share of currently installed pumps to be replaced with higher efficiency models. Glenn Wieczorek, Tsurumi’s managing ...

  • Car emissions: taking tests out of the lab and onto the road

    Every year 430,000 Europeans die prematurely due to air pollution. One of the main sources is road vehicles emitting nitrogen oxides (NOx), including poisonous nitrogen dioxide. Following the Volkswagen scandal, in which the company admitted cheating emission test in the US, Parliament and the Council are considering to update existing emission rules to ensure tests are closer to real driving ...

  • Black carbon emissions of individual cars measured under real conditions

    Measurements of individual vehicle emissions are usually made in laboratory tests. In this study, researchers followed cars driving in real conditions to measure emissions of air pollutants, including black carbon and nitrogen oxides. The study shows that diesel cars contribute disproportionately to air pollution, and highlights the value of on-road measurements. Vehicle traffic is a major source ...

  • Air pollution – the invisible roadside killer

    The VW emissions scandal has helped to raise awareness of the deadly threat posed by air pollution in many of our towns and cities. In the following article, Jim Mills, Managing Director of Air Monitors, an instrumentation company, explains why diesel emissions will have to be lowered and how the latest monitoring technology will be an essential part of the solution. ...

  • Monitoring CO2 emissions from new passenger cars and vans in 2014

    The European Environment Agency (EEA) supports the European Commission (EC) and European Union (EU) Member States in the monitoring of the carbon dioxide (CO2) performance of passenger cars, in accordance with Regulation (EC) No 443/2009, and of light commercial vehicles, in accordance with Regulation (EC) No 510/2011. The regulation for passenger cars sets a CO2 emission (1) target of 130 g ...

  • Evaluation of diesel fleet emissions and control policies from plume chasing measurements of on-road vehicles

    Abstract Vehicle emissions are an important source of urban air pollution. Diesel fuelled vehicles, although constituting a relatively small fraction of fleet population in many cities, are significant contributors to the emission inventory due to their often long mileage for goods and public transport. Recent classification of diesel exhaust as carcinogenic by the World Health ...

  • Wellpoint pumps help renovate sewerage system

    The sewerage system of the Danish city of Copenhagen was designed to handle routinely anticipated amounts of waste water and rainwater. However during heavy rainfalls, the system quickly loses its ability to process the excess volume of water. During the last few years such heavy storms have become more frequent in Copenhagen, therefore a decision was taken to separate the collection of rainwater ...
