Mechanical interface between engine and dynamometer, developed for each application
Testing an engine on a dynamometer bench requires a precise mechanical interface between the engine output — typically via the flywheel or clutch housing — and the dynamometer input shaft. Every combination of engine and test equipment has different geometry, alignment and torque requirements, making generic off-the-shelf solutions impractical.
NAPRO Eletrônica Industrial designs and manufactures custom couplings in machined cast iron, developed from the actual specifications of the engine and dynamometer — ensuring precise alignment, efficient torque transmission and operational safety during testing.
