Abstract
Abstract 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
155 words
An injector pod assembly for an engine comprising an injector mounting adapted to hold a fuel injector, said injectormounting having an inlet allowing entry of fuel into the fuel injector and a fastening means on its outer surface, said injector pod assembly further comprising a carrier to which said fastening means can be releasably attached to hold said injector mounting to said carrier, wherein said fastening means includes inlet and outlet ledges and said carrier includes an inlet latch engageable with said inlet ledge and an outlet latch engageable with said outlet ledge, and further comprising an inlet projection extending away from said injector mounting adjacent said inlet ledge, and an outlet projection extending away from said injector mounting adjacent said outlet ledge, wherein said inlet latch is engageable with said inlet projection and said outlet latch is engageable with said outlet projection to hold said injector pod in alignment with respect to said carrier.
Claim 2
Dependent Claim
155 words
An injector pod assembly for an engine comprising an injector mounting adapted to hold a fuel injector, said injectormounting having an inlet allowing entry of fuel into the fuel injector and a fastening means on its outer surface, said injector pod assembly further comprising a carrier to which said fastening means can be releasably attached to hold said injector mounting to said carrier, wherein said fastening means includes inlet and outlet ledges and said carrier includes an inlet latch engageable with said inlet ledge and an outlet latch engageable with said outlet ledge, and further comprising an inlet projection extending away from said injector mounting adjacent said inlet ledge, and an outlet projection extending away from said injector mounting adjacent said outlet ledge, wherein said inlet latch is engageable with said inlet projection and said outlet latch is engageable with said outlet projection to hold said injector pod in alignment with respect to said carrier.
Claim 3
Dependent Claim
191 words
An injector pod assembly for an engine comprising an injector mounting adapted to hold a fuel injector said injector mounting having an inlet allowing entry of fuel into the fuel injector and a fastening means on its outer surface, said fastening means comprising three resilient pod latches, each of said pod latches comprising a resilient spring arm extending away from said outer surface and a resilient finger integral with the end of said spring arm, said spring arms having the same length and lying in a single plane, said finger on the middle of said spring arms pointing in an opposite direction with respect to said fingers on the other of said spring arms, said injector pod assembly further comprising a carrier having an oblong opening to which said fastening means can be releasably attached by inserting the ends of said spring arms through said oblong opening so that said finger on the middle of said spring arms overhangs one edge of said oblong opening and said fingers on the other of said spring arms overhang the opposite edge of said oblong opening to hold said injector mounting to said carrier.
