Reduction of Fuel Delivery System Noise in a Passenger Car Using EBD (Experiment Based Design) Approach 2011-26-0071
As automobile design has become more sophisticated, the level of noise inside the vehicle has been dramatically reduced. The sources of noise which were previously ignored have now become relatively more significant, and it has become desirable to reduce the noise from such sources. The noise from the fuel system may be low but the fact that it operates continuously whether or not vehicle is moving, makes its noise level more noticeable.
So in order to achieve overall better NVH characteristics in a car it is important to minimize the noises from fuel delivery system. The current paper addresses the fuel pulsation noise from fuel delivery line and describes countermeasure approach for noise reduction using an Experiment Based Design approach (EBD).
