Design and Development of a Self-Contained Engine Stand for NVH Troubleshooting and Testing of Diesel Engines 2009-01-2083

Diesel engine NVH is an important characteristic of light and medium duty vehicles in today's market. Typical NVH related issues like idle gear clatter, gear whine and cab shake at low speed and load conditions are perceived as unpleasant and are unacceptable to the end customer. The root cause of many of these NVH concerns is frequently associated with powertrain structures and the excitation of different mechanical components within the engine. This paper focuses on development of robust and self-contained engine test stand which can help both for troubleshooting NVH concerns and for setting relevant targets at the subsystem levels to mitigate NVH risks. The motivation behind developing this unique test stand is given with examples and the advantages are demonstrated for relevant engine NVH testing applications.
