Abstract
The target performance of a new engine has to be obtained under various restrictions such as cost and weihgt. It is particularly important to predict the engine noise and vibration performance at an early stage.
For this purpose the analytical methods have been developed, which include the prediction of the absolute noise and vibration level by inputting a given exciting force into the model.
These methods were applied to the development of the new engine. As a result, the characteristics of an aluminum cylinder block were used effectively to achieve a new lightweight V6 engine with low noise and vibration levels.
