Claims25
An air cleaner assembly for an internal combustion engine in an underhood engine compartment, said air cleaner assembly comprising a bracket forming a combustion air flow passage therethrough, an air filter comprising a housing mounted to said bracket and having a dirty air inlet and a clean air outlet, a combustion air duct having an inlet receiving clean combustion air through said bracket and supplying said clean combustion air to said engine, said clean air outlet of said housing and said inlet of said combustion air duct each being sealed at said bracket, such that clean filtered air exits said air filter at said clean air outlet of said housing and flows through said combustion air flow passage of said bracket and through said inlet of said combustion air duct as said clean combustion air supplied to said engine.
A combination air filter element and base for an air cleaner assembly for an internal combustion engine in an underhood engine compartment, said air cleaner assembly having a bracket mounted to a designated component in said underhood engine compartment, said bracket forming a combustion air flow passage therethrough, said combination air filter element and base being part of an air filter comprising a housing having a cover detachably mounted to a base, said housing being mounted to said bracket and having a dirty air inlet and a clean air outlet, said combination air filter element and base including an air filter element having an upstream dirty side receiving dirty air from said dirty air inlet, and a downstream clean side delivering clean filtered air to said clean air outlet, said air filter element being integrally and permanently mounted to said base and defining a clean filtered air plenum therebetween, said combination air filter element and base being removed and replaced as a single unit from and to said housing, a combustion air duct having an inlet receiving clean combustion air through said bracket and supplying said clean combustion air to said engine, said clean air outlet of said housing and said inlet of said combustion air duct each being sealed at said bracket, such that clean filtered air exits said combination air filter element and base at said clean air outlet of said housing and flows through said combustion air flow passage of said bracket and through said inlet of said combustion air duct as said clean combustion air supplied to said engine.
A filter assembly comprising a housing comprising a cover detachably mounted to a base, said housing having a dirty fluid inlet and a clean fluid outlet, a filter element having an upstream dirty side receiving dirty fluid from said inlet, and a downstream clean side delivering clean filtered fluid to said outlet, said filter element being integrally and permanently mounted to said base and defining a clean filtered fluid plenum therebetween, said base and said filter element being removed and replaced as a single unit from and to said housing.
