  • Natural gas as a promising alternative fuel for passenger cars

    The present work (as a field study) investigated the role of compressed natural gas (CNG), as an automotive fuel in CO, HC and CO2 emissions in vehicle exhaust. Besides evaluating the influence of the fuel-feed systems into their cylinders on a vehicular emission level, two different systems were examined; electronic fuel-injection and well-carburetted engines. The chosen vehicles were ...

  • Dispersion modelling near tunnel exits: simulation and measurements

    Measurements of car exhaust gases were made in May/June 1995 in the vicinity of the Bielefeld tunnel. CO and NOx from car exhausts were measured to allow comparison with a model simulation. Ozone was also measured. These measurements were made using commercial continuous analysers. A valve control system was used to investigate the dispersion of the trace gases. This allowed measurements at ...

  • Who Needs Continuous Emissions Monitoring?

    Continuous emissions monitoring (CEM) is about monitoring air pollutants generated by a specific activity and emitted to the ambient air, typically through a tall stack or other exhaust pipe. The “activity” can be some industrial process like a power plant or a waste incinerator, but it can also be on a much smaller scale such as a car equipped with an internal-combustion engine. ...

  • Why measuring the ambient NO2 without conversion?

    Nitrogen oxides NOx are pollutants that may have particular impact in terms of greenhouse gases, acidifying air etc ... issuance increased significantly since 1950 with the massive development of transport and industries. It therefore becomes necessary to provide measures always safer these pollutant gases, and to know the reliability of results. Currently, 60% of emissions of NO and NO2 are ...

  • Evaluating 15 years of transport and environmental policy integration - TERM 2015: Transport indicators tracking progress towards environmental targets in Europe

    The Transport and Environment Reporting Mechanism (TERM) report has been monitoring progress in integrating environmental objectives into transport since 2000. TERM 2015 is launched at the end of the year in which the European Environment Agency (EEA) launched its report European environment: State and outlook 2015 (SOER 2015) (EEA, 2015a). SOER 2015 analyses the state of, trends in and prospects ...
