  • Forklift CO Emissions - Case study

    Measuring Exhaust Gases From Forklift Engines Many forklift trucks have internal combustion engines that burn propane, natural gas, diesel, or other fossil fuels. A portable combustion gas and emissions analyzer can be used to optimize combustion efficiency & maximize fuel savings, identify and quantify sources that can adversely affect safety and comfort in the work environment, ...

  • MARPOL ANNEX VI Compliance Using a Portable Emissions Analyzer - Case study

    Marine vessels can emit air pollution such as CO, CO2, NOx (NO+NO2), and SO2 from their diesel engines and onboard incinerators. MARPOL Annex VI and the technical code for control of emissions of nitrogen oxides (NOx Technical Code) issued by IMO are internationally recognized regulations for the prevention of air pollution and emissions from marine ...

  • 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 ...

  • 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 ...

  • 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 ...
