Abstract
An intake system of an internal combustion engine of a vehicle includes: an intake manifold configured to be fluidly coupled to a throttle valve and including intake runners for cylinders, respectively, of the internal combustion engine; and a plenum that includes a flange configured to receive gas from a valve of the vehicle, that is fixed to the intake manifold, and that includes apertures configured to flow gas from the plenum into the intake manifold one of: between ones of the intake runners; and directly into the intake runners.
Claims14
An intake system of an internal combustion engine of a vehicle, comprising:
- an intake manifold configured to be fluidly coupled to a throttle valve and intake runners for cylinders, respectively, of the internal combustion engine;
- and
- a plenum that includes a flange configured to receive gas from a valve of the vehicle, that is fixed to the intake manifold,
- wherein the plenum includes apertures configured to flow gas from the plenum into the intake manifold directly between adjacent ones of the intake runners,
- wherein the valve is one of a fuel vapor purge valve and a positive crankcase ventilation (PCV) valve.
An intake system of an internal combustion engine of a vehicle, comprising:
- an intake manifold configured to be fluidly coupled to a throttle valve and intake runners for cylinders, respectively, of the internal combustion engine;
- and
- a plenum that includes a flange configured to receive exhaust from an exhaust gas recirculation (EGR) valve of the vehicle, that is fixed to the intake manifold, and that includes apertures configured to flow exhaust from the plenum into the intake manifold directly between adjacent ones of the intake runners.
