Sec. 1065.15  Engine testing.

    (a) This part describes the procedures for performing exhaust 
emission tests on engines that must meet emission standards.
    (b) Generally, you must test an engine while operating it on a 
laboratory dynamometer over a prescribed sequence. (Subpart J of this 
part describes in-use testing of engines installed in vehicles or 
equipment.) You need to sample and analyze the exhaust gases generated 
during engine operation to determine the concentration of the regulated 
pollutants.
    (c) Concentrations are converted into units of grams of pollutant 
per kilowatt-hour (g/kW-hr) or similar units for comparison to emission 
standards. If the applicable emission standards are expressed as g/bhp-
hr, references in this part to kW should generally be interpreted to 
mean horsepower.
