Abstract
A muffler assembly has a housing and an internal and replaceable core assembly. The core assembly may contain emission reduction elements to reduce the emissions from the engine and/or sound reducing elements. The core assembly is replaced within the housing when the emission reduction elements become ineffective or when the user desired to otherwise replace the internal core assembly without replacing the muffler housing or assembly components. The core assembly may take the form of a sealed cartridge to isolate exhaust treatment apparatuses from the ambient environment.
Claims27
Muffler assembly used for a boat or vehicle, said muffler assembly being installed between the engine and the engine exhaust discharge point of said boat or vehicle, said muffler assembly having a generally permanent outer housing and a removable and replaceable internal core assembly which is inserted into and removed from said permanent outer housing, said muffler assembly and said internal core assembly having guide and positioning elements to correctly position said internal core assembly within said outer housing.
A replaceable internal core assembly for a muffler assembly, said internal core assembly being removable from said muffler assembly and comprising at least one sound reducing element and/or at least one emission reduction element, a sealing plate adapted to engage with said housing and to form a seal between said housing and said internal core assembly and means to guide said internal core assembly into said housing and to maintain said internal core assembly in a removable relationship with said housing.
A replaceable internal core assembly for a muffler assembly, said internal core assembly being removable from said muffler assembly and comprising at least one filter element, a sealing plate adapted to engage with said housing and to form a seal between said housing and said internal core assembly and means to maintain said internal core assembly in a removable relationship with said housing.
A replaceable internal core assembly for a muffler assembly, said internal core assembly being removable from said muffler assembly and comprising at least one emission reduction element, a sealing plate adapted to engage with said housing and to form a seal between said housing and said internal core assembly and means to maintain said internal core assembly in a removable relationship with said housing.
Method of installing a replaceable internal core assembly within a muffler assembly having a housing comprising the steps of inserting said replaceable internal core assembly through an opening in said housing, correctly positioning said internal core assembly within said housing and sealing said internal core assembly with and retaining said internal core assembly within said housing in a removable relationship with said housing.
A cartridge for insertion into a muffler casing, said cartridge containing at least one exhaust treatment element and being sealed prior to installation in said muffler casing, said cartridge containing an entrance for the ingress of exhaust from an engine and an exitway for the egress of said exhaust following treatment of said exhaust within said cartridge.
Method of treating exhaust emanating from an engine comprising inserting a cartridge into a muffler casing, allowing said exhaust from said engine to enter said cartridge, treating said exhaust within said cartridge to remove environmentally objectionable materials from said engine exhaust and allowing said treated exhaust to pass from said cartridge.
