Abstract

A silencer for an internal combustion engine of a motor vehicle having a turbocharger and a charge air cooler is provided. The silencer includes a turbocharger module with a passage duct. An inlet interface is fastened to an outlet connector of the turbocharger of the internal combustion engine. An outlet interface of the turbocharger module is fastened one or more modules configured as a resonator module and/or a charge air cooler module. An outlet interface of the module most remote from the outlet connector of the turbocharger is fastened to an inlet interface of a feed line for the charge air cooler of the internal combustion engine.

First claim

What is claimed is:

1. A silencer for an internal combustion engine of a motor vehicle having a turbocharger having a turbocharger connector and a charge air cooler having a feed line, the silencer comprising:
a turbocharger module having a first inlet interface configured to be fastened to the turbocharger connector, a first outlet interface and a first passage duct extending through the turbocharger module; and
a resonator module having a second inlet interface detachably fastened with a fastener to the first outlet interface of the turbocharger module forming a plug connection interface, a second outlet interface configured to be fastened to the feed line, a second passage duct extending through the resonator module and in communication with the first passage duct, and a resonator chamber in communication with the second passage duct via a choke formed in the resonator module.

2. The silencer according to claim 1 , wherein the resonator module comprises:
a first resonator element adjacent the second inlet interface having a first resonator chamber in communication with the second passage duct via a first choke formed in the first resonator element, and
a second resonator element adjacent the second outlet interface having a second resonator chamber in communication with the second passage duct via a second choke formed in the second resonator element,
wherein the first resonator element and the second resonator element are arranged in series between the turbocharger connector and the feed line.

3. The silencer according to claim 2 , wherein the first resonator chambers is designed for a first frequency range and the second resonator chamber is designed for a second frequency range which is distinct from the first frequency range.

4. The silencer according to claim 2 , wherein an outlet interface on each of the first and second resonator elements are configured to provide a common mating interface with the inlet interfaces of the first and second resonator elements such that the order of the first and second resonator elements are interchangeable.

5. The silencer according to claim 1 , wherein the resonator module comprises a first resonator element adjacent the turbocharger module having a first resonator chamber in communication with the second passage duct via a first choke formed in the first resonator element and a second chamberless charge air cooler element adjacent the second outlet interface.

6. The silencer according to claim 5 , wherein an outlet interface on each of the first resonator element and the second chamberless charge air cooler element are configured to provide a common mating interface with the inlet interfaces of the first resonator element and the second chamberless charge air cooler element such that the order of the first resonator element and the second chamberless charge air cooler are interchangeable.

7. The silencer according to claim 1 wherein the plug connection interface comprises a positively lockable connection.

8. The silencer according to claim 7 wherein the positively lockable connection comprises a locked plug connection interface.

9. A silencer kit used when assembling a silencer for an internal combustion engine of a motor vehicle having a turbocharger with a turbocharger connector and a charge air cooler having a feed line, the silencer kit comprising:
a first turbocharger module having a first turbocharger inlet interface, a first turbocharger outlet interface and a first turbocharger passage duct extending through the first turbocharger module;
a second turbocharger module having a second turbocharger inlet interface that is distinct from the first turbocharger inlet interface, a second turbocharger outlet interface and a second turbocharger passage duct extending through the second turbocharger module;
a first resonator module having a first resonator inlet interface configured to be detachably fastened with a first fastener to the turbocharger outlet interface of either the first or second turbocharger module forming a first plug connection interface, a first resonator outlet interface, a first resonator passage duct extending through the first resonator module and in communication with the passage duct of either the first or second turbocharger module, and a first resonator chamber in communication with the first passage duct via a first choke formed in the first resonator module;
a second resonator module having a second resonator inlet interface configured to be detachably fastened with a second fastener to the turbocharger outlet interface of either the first or second turbocharger module forming a second plug connection interface, a second resonator outlet interface, a second resonator passage duct extending through the second resonator module and in communication with the passage duct of either the first or second turbocharger module, and a second resonator chamber in communication with the second passage duct via a second choke formed in the second resonator module; and
a chamberless module having an inlet interface configured to be detachably fastened with a third fastener to the outlet interface of either the first or second turbocharger module or the first or second resonator module forming a third plug connection interface and an outlet interface;
wherein the silencer is assembled from a first module selected from the group consisting of the first turbocharger module and the second turbocharger module arranged in series with a second module selected from the group consisting of the first resonator module, the second resonator module, the chamberless module and combinations thereof for locating between the turbocharger connector and the charge air cooler connector.
