An integrated induction system for providing fluids to the cylinders in an engine comprises a casing adapted for mounting on the engine. The casing has an air inlet and a plurality of fluid outlets. A plurality of air tubes are disposed within the casing so that air entering the air inlet flows through the air tubes and respective fluid outlets to the cylinders. A fuel injection assembly is mounted within the casing to inject fuel into the air exiting the air tubes adjacent each of the fluid outlets causing a mixture of air and fuel to enter the respective cylinders. Connected to the fuel injection assembly is a carrier upon which are mounted induction system components. The casing is mounted on distribution mountings which are connected to the engine. The distribution mountings have passages to allow communication between air and fuel contained within the casing and the cylinders, and to allow communication between a supplemental fluid source and the cylinders.
An integrated induction system to provide fluids to the cylinders in an engine, comprising:
A locator system for an air tube inside a manifold casing for introducing air contained within the manifold casing to a cylinder in an engine, said locator system comprising a locator tab projecting from the outer surface of the air tube, and a locator rib extending inward from the inner surface of the manifold casing toward said locator tab so that said locator rib bears upon said locator tab to hold the air tube in the manifold casing.
A locator system for an air tube inside a manifold casing for introducing air contained within the manifold casing to a cylinder in an engine, said locator system comprising a locator tab projecting outward from the outer surface of the air tube, and a locator sleeve formed on the inner surface of the manifold casing adjacent said locator tab so that said locator tab can be inserted in said locator sleeve, said locator tab and locator sleeve being adapted to interlock with one another to hold the air tube in the manifold casing.
A distribution mounting for a manifold in combination with an engine having a plurality of cylinders, said distribution mounting being disposed between the manifold adjacent its outlets and the engine adjacent the cylinder inlets, said distribution mounting having a plurality of mounting passages wherein each of said mounting passages leads from the manifold to a respective cylinder to allow communication between the interior of the manifold and the cylinders, said distribution mounting further having a distribution passage including ports leading to at least two of said mounting passages, said distribution passage being in further communication with a supplemental fluid source to allow communication, via said distribution passage, between the supplemental fluid source and at least two of said mounting passages.
A distribution mounting for a manifold in combination with an engine having a plurality of cylinders, said distribution mounting being disposed between the manifold adjacent its outlets and the engine adjacent the cylinder inlets, said distribution mounting having mounting passages to allow communication between the interior of the manifold and the cylinders, and a distribution passage in communication with said mounting passages, said distribution passage being in further communication with a supplemental fluid source to allow communication between it and said mounting passages wherein said distribution passage comprises an elongate recess formed on the surface of said distribution mounting which mates with the engine, said recess having a longitudinal axis parallel to said surface of said distribution mounting which mates with the engines so that, when said distribution mounting mates with the engine, said recess is enclosed to form said distribution passage.
A distribution mounting for a manifold in combination with an engine having a plurality of cylinders, said distribution mounting being disposed between the manifold adjacent its outlets and the engine adjacent the cylinder inlets, said distribution mounting having mounting passages to allow communication between the interior of the manifold and the cylinders, and a distribution passage in communication with said mounting passages, said distribution passage being in further communication with a supplemental fluid source to allow communication between it and said mounting passages, said distribution mounting including an elongate mounting recess in its upper surface and further comprising an upper mounting gasket having a resilient stud extending from its lower surface, at least a portion of said stud having a cross section larger than said mounting recess, said stud having an elongate stud recess, said upper mounting gasket having an attachment opening concentric with said stud recess enabling insertion of a pin into said stud recess to urge said stud into said mounting recess to hold said upper mounting gasket to said distribution mounting so that, when said distribution mounting mates with the manifold, said upper mounting gasket is disposed between the manifold and said distribution mounting to provide a seal between them.
