Facilities

  • With the installation of the two large engine test cells and a small engines test area in our well equipped laboratory facility, AET has the ability to conduct both experimental and analytical research for both medium and high speed diesel engines, with output power per cylinder ranging from 1 - 300 kW. AET has a working agreement with Environment Canada (EC) [River Road Facility] to conduct steady state measurement of exhaust emissions for regulated major species, particulate measurements and non-regulated emissions. For final transient emissions assessment portable quick release engine attachments have been developed for effective movement of engines to EC's dilution tunnel.

  • In addition, AET has established a mobile data acquisition, sensor and instrumentation capability, which has been proven during significant test work carried out at several locations in Canada and the United States. This capability, which allows engine condition monitoring activities and field experimentation to be undertaken in the field, also forms the basis for field measurement of exhaust emissions.

  • Detailed capabilities for engine testing are indicated below.

DETAILS OF ENGINE TEST CAPABILITIES

High standards are maintained for all test activities undertaken. Electrical/electronic measurements are traceable to the U.S. National Bureau of Standards (NBS). Weights and measures are traceable to Consumer and Corporate Affairs Canada (CCA), as are measurements of gaseous volumetric flow rates. Measurements of liquid flow rates are performed on a mass basis wherever possible, and are traceable to CCA for mass measurements and the National Research Council for time measurements.

AET facilities/capabilities include:

  • dynamometers up to 600 hp with above ground liquid and gaseous fuel tank farm. Fuel reservoir capacity capable of extended engine durability testing;
  • Under an agreement with Environment Canada exhaust gas emissions testing for steady state diesel operation and multi-mode test formats;
  • the ability to test locomotive engines at an adjacent rail siding up to 6,500 hp;
  • the measurement of fuel consumption flow rates up to 1200 lb/hr (recent tests have demonstrated a repeatable accuracy level of 1 part in 10,000);
  • test cell temperature control plus or minus 2.5 °Cfor test cell temperatures from -20 to +50 °C with up to 15,000 cfm air through- put;
