A turbocharger heat shield is disposed around a turbocharger turbine housing and comprises first and second heat shield members each having a wall structure that is generally semi-cylindrical in shape. The heat shield members are removably attached with one and include axially opposed openings, and a radial opening, to accommodate passage of other turbocharger components therethrough. A third heat shield member may be included to cover a further element of the turbocharger. One or more tabs project from an edge of the first or second heat shield member to register with an adjacent edge of the other member to facilitate alignment, engagement and/or attachment between the two members. An insulating material can be interposed between the heat shield and the turbocharger housing and, in a preferred embodiment, is attached to the heat shield.

Turbocharger heat shield

A protective cover for an engine filter having a cover upper portion and at least one cover sidewall attached to the cover upper portion, wherein the cover upper portion and the at least one cover sidewall form an enclosure, such that an inner perimeter of the enclosure has a size and a shape similar to a size and a shape of an outer perimeter of the engine filter.

Protective filter cover

Air filter assemblies include an air filter housing with an air flow passageway extending therethrough, and a connection flange to facilitate attachment with an air filter member. The air filter member includes an annular air filter element disposed concentrically around the housing. The filter member has a closed top at one end and a retaining band at an opposite end that includes a connection base that is configured to attach with the housing connection flange. An attachment assembly is positioned over the housing connection flange and air filter member connection base to releasibly attach the air filter member to the air filter housing. An O-ring seal is interposed between the air filter housing and member to provide a leak-tight fit therebetween. A sound attenuating chamber is disposed within the assembly to control unwanted intake air noise therein. A vacuum monitor can be attached to the assembly to assess the remaining service life of the air filter element without need for visual inspection.

Air filter assembly

An air filter/oil separator assembly comprises a housing having an outer wall and a channel disposed therein between a primary gas inlet and a primary gas outlet. An air filter is joined to the primary gas inlet for filtering air from the immediate environment for introduction into an engine intake system. The housing includes a secondary inlet port through the outer wall, for receiving an air-oil mixture taken from an engine crankcase breather, and a secondary outlet port through the channel wall. A baffle is disposed axially within the housing and extends axially between the outer wall and the channel wall. The baffle, outer wall, and channel wall together define a first and second air flow passageway between the secondary inlet and secondary outlet ports. A removable filter element is disposed within at least one of the first and second passageways to capture air-borne particulate matter and/or aid in the coalescence and separation of oil within the air-oil mixture.

Serviceable air filter/oil separator assembly

Air-oil separators of this invention comprise a housing having an internal chamber defined by a housing sidewall surface that extends axially from a housing base to a housing open end. The open end includes a removable lid disposed thereon. The housing includes an inlet for receiving an air-oil mixture into the internal chamber from an internal combustion engine, and an outlet for passing a separated air stream from the internal chamber and out of the housing. An oil coalescing filter element is removably disposed within the internal chamber and is positioned/interposed between the inlet and outlet. A vacuum control device is disposed onboard or off board of the separator to provide a vacuum regulated environment within the housing internal chamber between the inlet and outlet. Thus configured, air-oil separators of this invention provide improved air and oil separation efficiencies when compared to conventional air-oil separators.

Remote air-oil separator

The combination apparatus silences and filters air flow, separates air-contaminant mixtures, and maintains a regulated vacuum therein. An air filter joins an annular housing which has an outer wall and a channel defining a central axis, the channel having a primary gas inlet coupled to the air filter and a primary gas outlet and a channel wall. The apparatus has a secondary inlet port passing through the outer wall. A secondary outlet port defines an opening in the channel wall such that there is no straight line flow path between the secondary inlet and the secondary outlet. An air silencer is contained within the channel. A passageway between the secondary inlet and the secondary outlet is defined exteriorly by the outer wall and interiorly by the channel wall. A vacuum regulating means is disposed within the annular housing and is positioned next to an opening in the secondary outlet to regulate the amount of vacuum imposed within the passageway so that it does not exceed a determined maximum.
