Abstract
A constrained layer damping system for use in an integrated air fuel module having a control module mounted thereon is provided. A control module and a wiring harness extending from the control module are coated with an encapsulant. A first layer of formed material is placed on a first side of the wiring harness and a first side of the control module, and a second layer of formed material is placed on a second side of both the wiring harness and the control module.
Claims19
A constrained layer damping system for use in an integrated air fuel module having a control module mounted thereon, said constrained layer damping system comprising:
- a control module coated with an encapsulant;
- a wiring harness coated with an encapsulant and extending from said control module;
- a first layer of formed material on a first side of said wiring harness and a first side of said control module;
- and
- a second layer of formed material on a second side of said wiring harness and a second side of said control module.
A constrained layer damping system, said constrained layer damping system comprising:
- a wiring harness coated with an encapsulant;
- a first layer of formed material on a first side of said wiring harness;
- and
- a second layer of formed material attached to a second side of said wiring harness such that said wiring harness is between said first and said second layers.
A method for reducing the effects of noise emitted from a powertrain and electromagnetic interference on a control module, said method comprising the steps of:
- providing a control module with a wiring harness extending therefrom;
- encapsulating said control module and said wiring harness with a damping material;
- mounting said control module on an air intake manifold plenum cover;
- and
- mounting a constraining layer of material on the side of said control module and said wiring harness opposite said air intake manifold plenum cover.
