Engine Exhaust Noise Test Facility 730427

A patented test facility has been developed for the purpose of analyzing exhaust noise emissions. The facility isolates the exhaust system noise source and allows noise tests to be conducted under the SAE J366a test site conditions.The exhaust system is piped and positioned in a manner similar to that found on the vehicle. Noise tests are conducted under steady state engine speed and load settings resulting in a high repeatability of test data.
