  • Quantitative analysis of automotive exhaust gas by Fourier Transform Infrared spectroscopy

    For monitoring gaseous emissions from muffler, instruments presently used can only measure quantitatively a given pollutant. Fourier Transform Infrared (FTIR) spectroscopy can provide quantitative and online real time analysis. Calibration of our FTIR spectrometer with CO, CO2, NO, NO2 and N2O was done and the limits of quantification obtained were shown to be as low as 80 ppm. The variation ...

  • 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 ...

  • Reducing NOx in Diesel Emissions | Spectroscopy Solutions

    Air pollution and NOx emissions from diesel engines are a global concern due to their potential impacts on human health.

  • VOC composition and ozone-forming potential of the exhaust gas of in-use motorcycles

    The emission profile of volatile organic compounds (VOC) and the ozone-forming potential (OP) of the exhaust gas of six in-use motorcycles (four 4-stroke- and two 2-stroke-engines) were determined. The motorcycles were tested on a chassis dynamometer in a real-world driving cycle. The analysis involved the C2–C12-hydrocarbons as well as the aldehydes and ketones. Additionally, the regulated THC ...

  • Reducing Routine Maintenance Costs of Engine Generator Sets with New Portable Oil Analysis Tools - Case study

    What do a hospital, a treatment plant a police station and a remote mine have in common? They have essential assets requiring uninterruptible power, commonly powered by an engine generator as primary or back up power. Engine generators, often termed "gen sets," combine an electrical generator and an engine. They supply electrical power where normal utility power is not readily available or is ...

  • Investigation of environmental impact caused by aircraft engines

    The environmental effects of exhaust gas emissions from different types of spark ignitions (SIs) - naturally aspirated and air–cooled from piston–prop aircraft engines - at the landing and take–off (LTO) phase of flight–based operations are investigated in this study. The minimum natural resources effect was determined to be 1.37 MJ surplus energy/LTO in 320 in three cylinder displacement and ...

  • 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 ...

  • How Gas Analyzers Can Benefit the Automotive Industry

    Emissions standards imposed upon auto engineering firms in the US could be set to change, as the Environmental Protection Agency reviews the current standards which have been in place since 2012. The EPA are considering redressing the greenhouse gas emissions standards for light-duty vehicles due for production in the model years 2022—2025, citing changing economic circumstances as the ...

  • 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 ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • Case study -New media makes RTO natural gas usage a rarity!

    Overview Tekra Corporation has always had an eye on their energy conservation. They are a custom coater of plastic films in Wisconsin where state regulations require over 98% of the Volatile Organic Compounds (VOCs) emitted from their process be destroyed in an oxidizer system. While considering their first oxidizer system, Tekra's Engineers did their homework and invested in an early ...

  • FTIR gas analyzer supports carbon capture research - Case study

    The development of carbon capture and storage (CCS) technologies relies on the accurate measurement of carbon dioxide (CO2) in addition to a wide array of other gases because it is vitally important that the process does not impact upon the emissions of other greenhouse gases and potential pollutants. An advanced FTIR multiparameter gas analyser from Gasmet Technologies is therefore being ...
