On power plant IC-engine source characterization in-situ

Abstract

In control of IC-engine exhaust noise, component level approach has been typically used. This has enabled development of new, cost-efficient silencers. However, prediction of sound emission from tailpipe end to the environment and even prediction of insertion loss of a silencer requires a more extensive, system level approach. In this regard, valid IC-engine source characteristics combined with a valid model of the whole transmission path are needed. In source characterization with multi-load method, the requirements for load impedance variation must be fulfilled. In automotive cases it is relatively easy to vary components, to test measurements methods and to conduct validation studies. Unfortunately, these practices are not feasible for large IC-engines used e.g. in power plants. This is due to the highly reactive silencers and quite high tailpipes, for example. This study aims to create knowledge and technical solutions which can be used in determination of the power plant IC-engine source characteristics in-situ. The results will help to improve the accuracy of models used to predict power plant IC-engine exhaust noise emission.
