Abstract
Ämnesord
Stäng
- A parameterization for combustion chamber cylinderpressures is tuned to measurements on an inline 6cylinder Diesel engine at different operating conditions.Both measured and modeled signals are filtered in thefrequency domain and according to the so called Lucasattenuation. Two different estimates of engine radiatednoise are obtained and compared in this fashion. Theinfluence of physically meaningful parameters on thefrequency contents of the final noise level is analyzed,as well as the contribution of the pressure trace of themotored engine. The scattering of data in the pressuresignal is calculated as a function of the crank angleallowing for statistical considerations.
