Abstract
An intake system for a vehicle engine includes an air cleaner and a plurality of throttle bodies. The air cleaner encases an air cleaner element in an air cleaner housing for filtering air flowing from an unfiltered air chamber to a filtered air chamber of the air cleaner housing. The throttle bodies control the amount of air supplied from the filtered air chamber to a cylinder head. Operating noise of the throttle bodies is minimized by situating the throttle bodies within the air cleaner housing. Operating noise of fuel injectors associated with the throttle bodies is minimized by situating the fuel injectors within the air cleaner housing.
Claims21
An intake system for a vehicle engine, said intake system comprising an air cleaner and a plurality of throttle bodies, wherein
- the air cleaner comprises an air cleaner housing and an air cleaner element disposed in the air cleaner housing, the air cleaner housing having an interior that is divided into an unfiltered air chamber and a filtered air chamber, wherein the air cleaner element is positioned within the air cleaner housing so as to filter air flowing therethrough from the unfiltered air chamber to the filtered air chamber, and
- wherein the throttle bodies control the amount of air supplied from said filtered air chamber to a cylinder head;
- wherein each of the throttle bodies comprises a substantially cylindrical pipe having a hollow bore formed therein, and a throttle valve including a throttle plate which is pivotally mounted inside the hollow bore of the throttle body;
- and wherein said throttle valves of said throttle bodies are situated inside of said air cleaner housing.
An intake system for a vehicle engine, said intake system comprising an air cleaner and a plurality of throttle bodies,
- wherein the air cleaner comprises an air cleaner housing and an air cleaner element disposed in the air cleaner housing, the air cleaner housing having an interior that is divided into an unfiltered air chamber and a filtered air chamber, wherein the air cleaner element is positioned within the air cleaner housing so as to filter air flowing therethrough from the unfiltered air chamber to the filtered air chamber;
- wherein the throttle bodies control the amount of air supplied from said filtered air chamber to a cylinder head;
- and wherein said throttle bodies are at least partially situated in said air cleaner housing;
- wherein said air cleaner housing includes a first, a second, and a third housing section, wherein each throttle body forms part of an intake subassembly, wherein each intake subassembly is connected to a cylinder head,
- wherein the first, the second, and the third housing sections are connected such that said second housing section is positioned between said first and third housing sections;
- wherein said first housing section is supported on the intake subassemblies;
- wherein said air cleaner element can be inserted into said first and second housing sections when said first and second housing sections are mutually connected but when said third housing section is removed, and
- wherein said air cleaner element is supported in the air cleaner housing between the third housing section and the second housing section.
An air intake system for an engine of a vehicle, said intake system comprising an air cleaner and at least one intake subassembly comprising a throttle body, an air duct pipe, and an air intake funnel, wherein
- said at least one intake subassembly is adapted to be mounted to a cylinder head of an engine,
- the air cleaner comprises an air cleaner housing and an air cleaner element, the air cleaner housing divided into an unfiltered air chamber and a filtered air chamber, the air cleaner element supported within the air cleaner housing such that air is filtered as it flows therethrough from the unfiltered air chamber into the filtered air chamber;
- wherein the throttle body and the air intake funnel are entirely disposed inside of the air cleaner housing.
An intake system for a vehicle engine, said intake system comprising an air cleaner, a plurality of throttle bodies, and a plurality of fuel injectors, wherein
- the air cleaner comprises an air cleaner housing and an air cleaner element disposed in the air cleaner housing, the air cleaner housing having an interior that is divided into an unfiltered air chamber and a filtered air chamber, wherein the air cleaner element is positioned within the air cleaner housing so as to filter air flowing therethrough from the unfiltered air chamber to the filtered air chamber, and
- wherein the throttle bodies control the amount of air supplied from said filtered air chamber to a cylinder head;
- wherein said throttle bodies are at least partially situated in said air cleaner housing;
- and wherein each of said throttle bodies has one of said fuel injectors operatively attached thereto inside of said air cleaner housing.
