汽油机燃烧噪声分离与预测研究
Study on Gasoline Engine Combustion Noise Separation and Prediction
摘要
Abstract
To control the noise of internal combustion engine and predict engine combustion noise during the engine initial design stage,a new methodology was presented.According to the principle of noise superposition and incylinder pressure decomposition,the combustion noise and combustion pressure can be extracted from the total noise and in-cylinder pressure.A model of combustion noise transfer function was built in this paper and it was used to predict the combustion noise of a new developed gasoline engine.The predicted result was verified by the experiment.The experiment proved that the approach presented in this paper can be used to evaluate combustion noise of gasoline engine during the development phase and is important in the process of reducing combustion noise and increasing acoustic quality.关键词
