  • Forklift Emissions Analyzers

    Forklifts are commonly used in warehouses of various size and capacity for the movement and shipping of goods; however, the unoptimized engines can produce excess quantities of silent and deadly CO gas that can risk the health and safety of the workers. When forklifts are brought in for service usually the CO gas isn't measured. If the CO gas isn't measured and the engine properly optimized then ...

  • An end to the problem of particle emissions

    Austrian biomass heating systems guarantee an 80% cut in emissions. Recent studies have shown that these modern domestic boilers offer a significant reduction in particles, emitting fewer contaminating agents than previous generation boilers and wood stoves – with more than 100mg / ml of particles. The future will be based on new biomass combustion technology which cuts dust emissions from ...

  • Shipping Emissions - The Environmental Case for Sea Water Scrubbing

    The romantic image of a luxury liner cruising blue seas amid blue skies and trailing a plume of smoke is too close to the truth for comfort. The emissions from shipping make an increasingly conspicuous contribution to air quality, health and environmental problems of Europe, and indeed, the world. Yet an effective and safe technology to dramatically reduce these emissions is being discouraged, ...


  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • A study on the amount of pilot injection and its effects on rich and lean boundaries of the premixed CNG/air mixture for a CNG/diesel dual-fuel engine

    A sequential port injection, lean-burn, fully electronically-controlled compressed natural gas (CNG)/diesel dual-fuel engine has been developed based on a turbo-charged and inter-cooled direct injection (D.I.) diesel engine. During the optimisation of engine overall performance, the effects of pilot diesel and premixed CNG/air mixture equivalence ratio on emissions (CO, HC, NOx, soot), ...

  • Low-mass PM analyzer MEXA-1370PM — Improvement of the Performance for PM Composition Analysis —

    Particulate matter (PM) emitted from engines is currently measured by the filter weight method. The filter weight method passes diluted emission gases through a filter collecting the PM, and post test weighs the mass of the collected PM on a precision balance. However, this method is time consuming, and with decreasing PM emission volumes, improvements in accuracy were needed. So the MEXA-1370PM ...

  • Environmental impact of using biodiesel as fuel in transportation: a review

    The environmental pollution and global warming associated with the use of fossil fuels, has forced a search for alternative fuels in transportation. This paper presents a review of the use of biodiesel in CI engines and its environmental impacts. There is a significant reduction in the emission of unburned hydrocarbons, polyaromatic hydrocarbons and soot, particulate matters, carbon monoxide, ...

  • Exhaust Gas Treatments for NOx Reduction to Add to Global Warming

    The enforcement of year 2007 stringent emission norm for reduced NOx reduction/oxides of nitrogen gases from the diesel exhaust and the after treatment to reduce them will add to global warming by several fold according to renowned engine combustion kinetics, emission control process expert and inventor -Mr.Srinivasan Gopalakrishnan, Hydrodrive Systems & Controls Pvt. Ltd, India. His invention ...

  • On-Vehicle Exhaust Gas Cooling in a Diesel

    ABSTRACT A diesel emissions control system built and tested on an industrial forklift truck is described. The system utilizes a pleated media type diesel soot filter. The temperature limit of the filter material is well below the temperature of the exhaust gas. Therefore, cooling of the exhaust gas is ...

  • Fast Action to Reduce the Risks of Climate Change: U.S. Options to Limit Short-Lived Climate Pollutants

    Short-lived climate pollutants such as soot, methane and hydroflurorocarbons (HFCs) account for 30 to 40 percent of global warming to date. Targeted efforts to reduce these emissions can slow the pace of global warming and moderate climate impacts already underway, including the melting of sea ice and glaciers. By reducing local air pollution, such measures would also produce substantial public ...

  • 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 ...

  • Black Carbon – the elephant in the room!

    Traditionally, ambient particulates have been measured gravimetrically according to their size. However, in this article Jim Mills, Managing Director of Air Monitors, will demonstrate that the time has come to change or at least augment the way ambient particulates are monitored and regulated. Air Monitors has supplied most of the UK's ambient monitoring network, but Jim will explain why the ...

  • 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 ...
