Air cooled dynamometer vehicle emissions test stand

Abstract From the Canadian patent

An air-cooled eddy current dynamometers for the use in a vehicle emissions test stand application. The dynamometer housing includes an air inlet manifold for drawing cooling air radially inwardly into the dynamometer and an air outlet manifold permitting the expulsion of heated air tangentially outwardly from the dynamometer. An end of the dynamometer housing has a plurality of openings therein allowing cooling air to be drawn axially inwardly into the dynamometer housing. The combination of air flows radially inwardly through the inlet manifold, axially inwardly through the openings in the end of the dynamometer and tangentially outwardly through the outlet manifold significantly increases …
