  • Engine induction system
    Patent number: 4886020
    Abstract: An internal combustion engine has a tuned induction system with an air cleaner connected by a conduit with a separate plenum mounted on a manifold with individual runners connecting with the engine cylinders. A throttle body having a throttle to control induction air flow is located between the plenum and the manifold with its runner such that the plenum is not subject to reduced manifold pressures resulting from throttling the air flow.

  • Motor vehicle with intake manifold system
    Patent number: 4628873
    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.
