  • Emissions Testing

    What Is Stack Emissions Testing? Stack emissions testing (stack sampling or stack monitoring) is the experimental process for evaluating the characteristics of waste gas stream emissions into the atmosphere from industrial facilities to meet environmental standards. Stack testing measures the amount of specific regulated pollutants or surrogates being emitted or determines ...

    Presented in Track B4: EMISSION TESTING & MONITORING at EUEC 2011, January 31 Phoenix, Arizona B4.1  | Update on PM2.5 and Condensable Particulate Matter Emissions Measurement Methods Larry Hottenstein |  Partner, Environmental Resources Management Following the promulgation of the PM2.5 ...

  • Coal-rock dynamic disaster assessment model based on electromagnetic emission and least-squares support vector machine

    A new non-linear assessment model for coal-rock dynamic disasters is reported in this paper. Coal-rock dynamic disaster assessment parameters are difficult to obtain because assessment samples are usually rare. The least-squares, a non-linear and few sample assessment methods can satisfy requirements on the availability of few samples. Based on the electromagnetic emission (EME) testing results ...

  • Partial Flow Sampling System For Transient Engine Testing

    For on-highway engine manufacturers, meeting model year 2007 emissions levels represents a major measurement challenge. However, future off-road engine emissions testing requirements are anticipated to include not only lower steady-state emissions levels, but also the possibility of using transient cycle data. As a result, engine manufacturers are seeking more cost-effective methods of ...

  • Genset locomotive repower project - CSX transportation case study

    In December of 2007, CSX Transportation, in cooperation with PSEG Fossil LLC and NESCAUM, began a project to modernize three conventional switch locomotives to a more efficient and less polluting design.  Each locomotive engine was replaced with two smaller power packs, each equipped with a diesel particulate filter (DPF).  These locomotives are now cleaner, quieter, and more energy ...

  • Reducing the cost of emissions testing – Case Study

    In the early 1970¹s, the U.S. Environmental Protection Agency (EPA) was formed in response to growing concern about air quality. The EPA developed emissions regulations that targeted the carcinogenic impact of engine exhaust, and set tough regulatory standards for manufacturers to develop cleaner engines. Engine makers needed an instrument that could accurately measure the quantity of ...

  • Car emissions: taking tests out of the lab and onto the road

    Every year 430,000 Europeans die prematurely due to air pollution. One of the main sources is road vehicles emitting nitrogen oxides (NOx), including poisonous nitrogen dioxide. Following the Volkswagen scandal, in which the company admitted cheating emission test in the US, Parliament and the Council are considering to update existing emission rules to ensure tests are closer to real driving ...

  • The characteristic differences in exhaust emissions, and fuel consumption analysis of unleaded gasolines produced by different oil companies in the Turkish market

    In Turkey, the differences in the properties of gasolines that are taken from different petrol stations are intensively discussed. By taking this as a starting point, the main target of this project is to examine these differences and how they affect exhaust emissions. The properties of nine gasoline samples taken from nine different petrol stations that belong to three different oil companies ...
