  • Nine out of ten air pollution deaths occur in developing nations

    More than 90% of air pollution-related deaths occur in low- and middle-income countries, with seven million fatalities recorded around the world every year. That is according to data from the World Health Organization (WHO), which reveals that Asia and Africa are the regions worst ...

  • Smart cities risk reputation with poor air quality data

    The team at AQMesh continue to receive many enquiries from smart city initiatives and are concerned that integrators risk undermining entire projects by distributing meaningless or misleading air quality information. “Many of the people I speak to are used to dealing with sensors that are easy to ‘plug and play’ and expect to be able to do the same with air quality sensors. This ...

  • 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? ...

  • AQMesh used to measure local air quality at Surrey school

    Cleves School in Weybridge, Surrey (UK) has used AQMesh to measure pollution at the primary school’s entrance. The project, led by Dr. Edward Salter over the school’s summer term, aimed to understand exposure of the children (aged 7-11) to dangerous pollutant gases, with particular interest in the levels of nitrogen dioxide (NO2) and ozone (O3). Initial findings showed that levels of ...

  • 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 ...

  • London’s reliance on diesel triggers re-emergence of an old enemy: smog

    It’s Christmastime on Oxford Street. Brilliant displays of white lights rain from above. Decked-out shoppers dash from one gaudy sale to the next. And Johnny Conquest breathes in poison. “The air is horrible. The taxis stop right here, and when they take off, boom, you can taste it,” says the 67-year-old as the heavenly smell of the caramel peanuts he hawks from a humble street ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Air emissions associated with decommissioning California's offshore oil and gas platforms

    The 27 oil and gas platforms offshore southern California are nearing the end of their productive lives and will be decommissioned in the near future. Many are in deep water and are correspondingly large, with the largest, Harmony, in 1200 feet of water weighing approximately 43,000 tons. Nearly 30% of California's platforms are in water depths that exceed those of any previous decommissioning ...

  • Hydro Nano Gas could be the Answer for Neutralizing Carbon Fuel Emissions

    Hydro Infra Technologies (HIT), a Swedish clean tech company based in Stockholm, has developed an innovative patent pending approach for neutralizing carbon fuel emissions by generating a novel gas called Hydro Nano Gas (HNG). In spite of all the advancement happening in the energy sector, globa economies are ...

  • Air quality in Europe - 2014 report

    Despite considerable improvements in the past decades, Europe is still far from achieving levels of air quality that do not pose unacceptable risks to humans and the environment. Air pollution is the top environmental risk factor of premature death in Europe; it increases the incidence of a wide range of diseases and has several environmental impacts, damaging vegetation and ecosystems. This ...

  • Monitoring CO2 emissions from passenger cars and vans in 2013

    The European Environment Agency (EEA) supports the European Commission in the monitoring of the CO2 performance of passenger cars, in accordance with Regulation (EC) 443/2009, and of light commercial vehicles in accordance with Regulation (EC) No 510/2011. The regulation for passenger cars sets a CO2 'specific emission' (1) target of 130 g CO2/km by 2015 whilst the regulation for light commercial ...

  • Air quality issues drive vehicle alternatives

    Vehicle exhaust systems remain a major source of air pollution in cities, despite the progress being made to reduce emissions from new models. Energy World takes a look at efficiency improvements, and the alternative fuel alternatives to petrol and diesel. In early April, the south of Britain woke to a hazy blanket of smog. A few weeks earlier, Paris had choked and spluttered through its own ...

  • Emissions Reduction with Diesel Blending

    Diesel technologies are develops by huge rates. Modification of cars with diesel engines make a half of the new cars sold in Europe. The black smoke, noisy engine operation and unpleasant smell remained far in the past. Today diesel engines present not only profitability, but also high capacity and worthy dynamic characteristics. Quality of fuel also is changed. The modern diesel blending has ...

  • Secondary organic aerosol formation from naphthalene roadway emissions in the South Coast Air Basin of California

    Naphthalene is the simplest and most abundant polycyclic aromatic hydrocarbon (PAH) in California fuels, with concentrations of up to 2,600 mg L –1 in gasoline and 1,600 mg L –1 in diesel fuel.
