  • 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 ...

  • Time-resolved ammonia measurement in vehicle exhaust

    The objective of this study was to identify the influence of sampling and analytical approach on the quality of NH3 emission data of a gasoline-fuelled three-way catalyst vehicle. NH3 concentration measurements have been performed in the tailpipe and in the diluted exhaust after a constant volume sampling (CVS) system during five different test cycles. Chemical ionisation mass spectrometry ...

  • 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 ...

  • 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 ...

  • Evaluation of various theories of the thickness and curvature approximations for free vibrational analysis of cylindrical and spherical shells

    Cylindrical and spherical shells are largely used in several engineering fields, especially in aerospace vehicles as structural elements and in automotive vehicles as shafts or exhaust and induction systems. Due to their particular relations with vibrations of automotive structures, this work compares various significant shell theories to evaluate the free vibration response. Thin shell theories ...

  • Case study - Paint booth over spray

    OVERVIEW A major automotive component supplier needed to control the emissions from its paint spray process. The plant emissions had characteristics common to many paint spray plants: high air flow, low volatile organic compound (VOC) concentration and particulate. The company needed an emission control solution that had low operating costs and that could also fit in their limited ...

  • Controlling Pharmaceutical Coating & Drying Process Emissions

    Capturing and destroying harmful emissions from pharmaceutical processes can be challenging. It’s not because the volatile organic compounds (VOCs) are difficult to destroy using catalytic or thermal techniques. It’s because their concentrations can be so high. These process streams raise safety concerns, both when they’re collected in vents and when they reach the final ...

  • Fine-tuning acoustic isolation in buildings

    ACCIONA Infrastructure is ranked among the leading construction companies in the world - and is recognised for implementing the most advanced and innovative technology.  As research and design is vital to keep the company at the cutting edge in relation to technological developments, ACCIONA Infrastructure created a team to analyse noise and vibration. Where traditional ...

  • Concentrator - Plant Reduces Utility Expenses with New Emission Control System - Case Study

    The steadily increasing natural gas prices near the end of 2004 were becoming a substantial operating cost burden on a facility producing automotive paint and coatings and developing coating products. The major consumers of natural gas at this facility were the main system of boilers which supplied steam energy throughout the facility and two Regenerative Thermal Oxidizers (RTOs) which controlled ...
