ACOUSTIC DEVELOPMENT OF THE BMW 12-CYLINDER ENGINE

The customer is demanding higher and higher standards of vehicle performance, environmental compatibility and comfort. When a new engine is being developed, these aspects have a particularly high status. Legislative requirements, limiting noise emissions even further, are also added to this. Both these aspects mean that, in the development of new engines, engine noise and vibration excitation must be as low as possible. In the development of the 12-cylinder engine for the top of the range BMW 750i considerable importance was attached to combining sportiness with optimum passanger compartment comfort. The principles of developing an acoustically optimum engine are essentially already known. The report illustrates how, by subsequently applying the theory, the acoustic development of the new BMW 12-cylinder engine was carried out.
