  • Case study - Engine cell exhaust: Catalytic oxidizer

    Overview Endurance testing of outboard motors for boats has typically been done in lakes and sometimes on barges. This testing was time consuming, presented logistic problems and removed the testing from the R & D department and the factory. When a company in Oklahoma decided to build their own endurance test cell area, the Environmental Protection Agency required them to control the ...

  • Combustion, performance and emission analysis of diesel engine fuelled with methyl esters of Pongamia oil

    The methyl esters of vegetable oils, known as biodiesel are increasingly becoming popular because of their low environmental impact and potential as a green alternative fuel for diesel engine, and that they would not require significant modification of existing engine hardware. Methyl ester of Pongamia oil (PME) is derived through transesterification process. Experimental investigations have been ...

  • Experimental study on the performance of multi cylinder diesel engine fuelled by hydrogen/diesel blend

    Nowadays, the depletion of conventional fuel and greenhouse issues are the major crisis facing the life of human beings. Hydrogen is expected as one of the most promising renewable energy source to substitute the conventional fuel and meet the stringent emission norms. In this experimental investigation, the performance analysis was carried out on an indirect injection (IDI) diesel engine using ...

  • 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 ...

  • Thermal Desorption-GC/MS Analysis of polycyclic aromatic hydrocarbons on fine particulates in air

    Polycyclic aromatic hydrocarbons (PAHs) are commonly found throughout the environment in soil, water and adsorbed to fine particulate matter in air. Of the 16 common PAHs, 7 have been classified as animal carcinogens by the International Agency for Research on Cancer (IARC). Resulting from this classification, PAHs are monitored and regulated in the environment. Analysis of PAHs in soil and water ...

  • An experimental investigation of the performance and emissions characteristics of a direct injection compression ignition engine running with LPG

    Existing diesel engines are under stringent emission regulation particularly of smoke and particulate matter in their exhaust. The potential benefits of using liquefied petroleum gas (LPG) as an alternative fuel in diesel engines are both economical and environmental. In the present paper an experimental research was carried out on an I.C. engine laboratory single cylinder, four-stroke variable ...

  • Reaching Euro VI emissions limits

    The requirements of low and lowest detectable exhaust analysis has prompted Eco Physics to launch a broad range of analyzers for NO/NOx detection. Emissions tuning is one of the targets of the EURO VI regulations as well as US EPA 2010, which are: Reduction of Particulate Matter (PM) and reduction of Nitrogen Oxides (NOx). In the past 15 years – since the first European regulation for exhaust ...

  • Comparing TGA, FTIR and fixed filter infrared analyzers for measuring soot levels in in-service lubricants

    Measuring soot in diesel engine oil has become more important as soot levels get higher due to exhaust gas recirculation. As soot isone of the key indicators for the condition of the oil, diesel engine maintenance programs performing regular soot checks can realize cost savings by extending drain periods and reducing used oil disposal. TGA (Thermal Gravimetric Analysis) is the traditional method ...

  • Common Treatment Technologies for Halogenated VOCs in Soil, Sediment and Sludge

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with halogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific analysis ...

  • Common Treatment Technologies for Nonhalogenated VOCs in Soil, Sediment and Sludge

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil.

  • Dredging Up Power

    Caterpillar Marine was selected to power three 3500 m³ trailing suction hopper dredgers for the Jan De Nul Group with Cat 3500E IMO III and EPA Tier 4 certified engines. Cat said the 3500E incorporates selective catalyst reduction (SCR) after-treatment technology with closed-loop NOx sensing and application optimized performance for minimized owning and operating costs. “Embedded ...

  • Midwest contractor turns pollution into profits - Fred Weber

    Ed Moss knows a good thing when he sees one.  When Moss, maintenance manager for the major construction firm of Fred Weber, Inc., first tried out a fuel-saving device on one of the company’s diesel engines, something clicked right away.  Those first test results, conducted on an engine loading limestone at a mine, showed a fuel savings of 33 per cent, Moss said. What’s more, when his ...

  • Analysing coloured smoke | Pearl or Quest?

    Coloured smoke consists of an aerosol of tiny particles which is combusted or vaporized. The particular pigment or dye of each colour affects the colour of the smoke. The mixture usually includes a cool-burning formula based on potassium chlorate oxidiser, dextrin or lactose as fuel. Then one or more dyes are introduced to account for around half of the mixture. A small amount of sodium ...

  • New NO2 air standards prove technically challenging

    On February 9, 2010, the U. S. Environmental Protection Agency (EPA) established a new National Ambient Air Quality Standard (NAAQS) for nitrogen dioxide (NO2). The new NO2 NAAQS is a one-hour standard set at 100 parts per billion (ppb), which is approximately 188 micrograms per cubic meter (μg/m3). Effective on April 12, 2010, the new one-hour standard is intended to protect against peak ...
