  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • Engine Testing

    Engine testing involves measurement of rotating speed and torque of the engine by applying load controlled by a dynamometer connected to its output shaft. HORIBA has developed various types of dynamometer for the purpose of engine testing. They are mainly classified into two types; one is absorbing only dynamometer such as hydraulic dynamometers and eddy-current dynamometers, the other is ...

  • Emission Testing of Engines to be Installed in Non-Road Mobile Machinery

    The European Commission has founded a project on emission testing – 'Emission Testing of Engines to be installed in Non-Road Mobile Machinery'. The project was undertaken by Abgasprüfstelle Berlin-Adlershof GmbH in Germany. The work is a part of emission inventory of spark-ignition engines to be used as a basis for a future amendment of the Directive 97/68/EC. The inventory covers seven different ...

  • NO x emission model of turbofan engine

    During last decade a lot of investigations also focused on the evaluation of aircraft engine impact on local and regional air quality in the vicinity of the airport. The emission inventory of aircraft engines are usually calculated on the basis of certificated emission indexes, which is provided by the engine manufacturer and reported in the database of ICAO. The certificated emission indices ...

  • Case study - Engine test cell exhaust: RTO

    Overview A Mid-western outboard engine manufacturer bought a three year-old plant for the production of its marine engines. When finished, the engines are removed from the assembly line and run for quality control. The 25,000 SCFM of exhaust from testing contains volatile organic compounds (VOCs) that require regulatory compliance. Also within this exhaust is a great deal ...

  • Vibration monitoring and analysis in aircraft engine test cells

    Snecma, part of the SAFRAN group, is dedicated to the production of engines for both air and space. Working alone or in partnership, Snecma designs, develops and produces engines for civil and military aircraft, launch vehicles and satellites. The company is organised in three divisions: Commercial Engines – Snecma and GE Transportation team up to produce the bestselling family of CFM56 ...

  • Characterising emissions from private passenger vehicles using engine operating patterns

    A method to simulate emissions factors using frequency distribution plots of engine speed and engine load is proposed. The distribution plots and corresponding emissions factors were developed from speed time series’ of real-world driving cycles and physical properties of a range of private passenger vehicles tested at the EMPA. Emissions factors were estimated for a set of simultaneously ...

  • Performance and emission characteristics of CI engine, fuelled with diesel and oxygenated fuel blends

    Vegetable oils are a potential alternative towards partial or total substitution of diesel fuels. In this study, we used ethanol as the solvent, and a bio fuel enhancer as additive to explore the possible use of higher percentages of biodiesel in an unmodified diesel engine. Biodiesel was produced from cashew nut shell liquid (CNSL) by pyrolysis process. A mixture containing 80% (by volume) of ...

  • The emission characteristics of a compression ignition engine operating on castor oil methyl ester

    Diesel vehicles are a major form of transportation, especially in developing countries. Recent concerns over the environment, increasing fuel prices and the scarcity of its supply have promoted interest in the development of alternative sources of petroleum fuels. In this investigation, castor oil methyl ester was prepared by transesterification using potassium hydroxide (KOH) as a catalyst and ...

  • Effect of EGR on performance and emission characteristics of diesel engine at advanced injection timing

    This work attempts to reduce the smoke density of diesel engine by advancing the fuel injection timing and also the NOx emission of the engine by introducing EGR at the advanced injection timing. A single cylinder 4.4 kW air cooled, naturally aspirated, stationary diesel engine was utilised for the investigation. Engine tests were conducted at different loads at standard injection timing and ...

  • Development of automotive DI diesel engine to comply with stringent emission norms

    Relatively lower fuel energy cost, higher fuel conversion efficiency and ability to take higher loads are the attracting features of direct injection diesel engines. However, diesel engines are still posing the challenges to both researchers and manufacturers in terms of high soot and NOx emissions. To overcome these difficulties, small diesel engine manufacturers are ...

  • Study of the performance and exhaust emissions of a spark-ignited engine operating on syngas fuel

    To resolve the problem of depletion of petroleum based liquid fuels, various solutions have been proposed. One of them is the use of gaseous fuels that are generated from the gasification of woods, namely syngas or wood-gas fuels, as full supplement fuels in spark ignition internal combustion (IC) engines. This fuel consists of nearly 40% combustible gases, mainly hydrogen and carbon monoxide ...
