Abstract
Abstract In a motor vehicle having an engine intake manifold system, a plenum from which individual intake conduits extend to the cylinders of the engine is mounted to a portion of the vehicle structure, such as the firewall of the vehicle body. This enables the use of straight, relatively long intake manifold pipes, an arrangement which increases engine efficiency and which yields higher torque values at low engine speeds.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
81 words
In a motor vehicle having a body and an internal combustion engine including a performance tuned intake manifold system comprising an enlarged plenum shared by a plurality of engine cylinders and a plurality of long air intake conduits extending individually between the plenum and intake ports connecting with the cylinders, the improvement wherein to provide room for the long intake conduits the plenum is rigidly mounted, independently of the engine, on a portion of the vehicle body spaced from the engine.
Claim 2
Dependent Claim
81 words
In a motor vehicle having a body and an internal combustion engine including a performance tuned intake manifold system comprising an enlarged plenum shared by a plurality of engine cylinders and a plurality of long air intake conduits extending individually between the plenum and intake ports connecting with the cylinders, the improvement wherein to provide room for the long intake conduits the plenum is rigidly mounted, independently of the engine, on a portion of the vehicle body spaced from the engine.
Claim 3
Dependent Claim
40 words
In a motor vehicle according to claim 1 wherein the engine is mounted traverse and the body includes a firewall longitudinally spaced from the engine, the further improvement wherein the plenum is mounted on the firewall of the vehicle body.
Claim 4
Dependent Claim
43 words
In a motor vehicle according to claim 1 wherein the engine is mounted longitudinally and the body includes wheel housing spaced laterally from the engine, the further improvement wherein the plenum is mounted on one of the wheel housings of the vehicle body.
Claim 5
Dependent Claim
42 words
In a motor vehicle according to claim 1, the further improvement wherein to accommodate motion between the engine and vehicle body the intake conduits are rigidly connected to the intake ports and each intake conduit terminates in a bellows at the plenum.
