Abstract

An intake manifold is adapted for use with an engine in a front wheel drive vehicle and a rear wheel drive vehicle, for example, with both a transversely mounted and longitudinally mounted engine. The intake manifold is modular and includes a plenum body defining a first port and a second port. A series of runners are adapted to connect to the plenum body. A throttle body connector is adapted to connect to the first port and the second port based on the engine positioning in the vehicle. An end plate is adapted to connect to the first port and the second port.

First claim

What is claimed is:

1 . A vehicle comprising:
an engine; a modular intake manifold comprising a plenum body defining first and second ports on opposed ends with substantially identical cross-sections, a throttle body connector, an end plate, and runners for connecting the intake manifold to the engine, the plenum body having a longitudinal axis generally parallel with a longitudinal axis of the engine, each of the first and second ports sized to receive one of the throttle body connector and the end plate; and a pair of tractive wheels receiving torque from the engine to propel the vehicle, the pair of tractive wheels positioned for one of front wheel drive and rear wheel drive; wherein the throttle body connector is connected to the first port and the end plate is connected to the second port when the pair of tractive wheels are positioned for front wheel drive; and wherein the throttle body connector is connected to the second port and the end plate is connected to the first port when the pair of tractive wheels are positioned for rear wheel drive.

2 . The vehicle of claim 1 wherein the longitudinal axis of the manifold is generally transverse to a longitudinal axis of the vehicle in front wheel drive; and
wherein the longitudinal axis of the manifold is generally parallel to a longitudinal axis of the vehicle in rear wheel drive.

3 . A modular intake manifold adapted for use with a transversely mounted engine and a longitudinally mounted engine, the manifold comprising:
a plenum body defining first and second ports on opposed ends of the body, each port with substantially identical cross sections and sized to receive one of a throttle body connector and an end plate; and a series of runners connected to the plenum body and positioned between the first and second ports.

4 . A modular intake manifold of claim 3 further comprising:
a throttle body connector; and
an end plate.

5 . The intake manifold of claim 4 wherein the throttle body connector is connected to the first port of the plenum body and the end plate is connected to the second port of the plenum body in a transversely mounted engine.

6 . The intake manifold of claim 4 wherein the throttle body connector is connected to the second port of the plenum body and the end plate is connected to the first port of the plenum body in a longitudinally mounted engine.

7 . The intake manifold of claim 4 wherein the throttle body connector defines a third port and a fourth port, the third port adapted to connect to one of the first and second ports, the fourth port adapted to connect to an electronic throttle body.

8 . The intake manifold of claim 7 wherein the throttle body connector is an elbow connection.

9 . The intake manifold of claim 7 wherein the throttle body connector defines at least one of an exhaust gas recirculation mount, a positive crankcase ventilation mount, and a canister purge valve mount.

10 . The intake manifold of claim 4 wherein the throttle body connector is a first throttle body connector, the intake manifold further comprising:
a second throttle body connector adapted to connect to the first port and the second port.

11 . The intake manifold of claim 4 wherein the end plate defines a sensor housing.

12 . The intake manifold of claim 3 wherein the first port and the second port are spaced apart along a longitudinal axis of the plenum body.

13 . The intake manifold of claim 12 wherein the longitudinal axis of the plenum body extends through the first and second ports.

14 . The intake manifold of claim 3 wherein the first port and second port are each provided with a first fitting; and
wherein the throttle body and the end plate are each provided with a second fitting adapted to mate with the first fitting.

15 . The intake manifold of claim 14 wherein the first fitting is one of a male and a female connector, and wherein the second fitting is the other of the male and the female connector.

16 . The intake manifold of claim 15 wherein the male fitting is an inner sleeve and the female fitting is an outer sleeve.

17 . A method of providing an intake manifold for an engine, the method comprising:
connecting runners of an intake manifold to a head of an engine transversely mounted in a vehicle, the intake manifold having a throttle body connector attached to one of a first end region and second end region of a plenum body and an end plate attached to the other of the first end region and second end region.

18 . The method of claim 17 further comprising connecting runners of the intake manifold to the head of the engine longitudinally mounted in the vehicle, the intake manifold having the end plate attached to one of the first end region and second end region of the plenum body and the throttle body connector attached to the other of the first end region and the second end region.

19 . The method of claim 17 further comprising forming the intake manifold by:
forming the plenum body with a first port and a second port, the first and second ports having a first fitting;
forming the end plate with a second fitting adapted to mate with the first fitting; and
forming the throttle body connector with the second fitting.

20 . The method of claim 19 further connecting the throttle body connector and the end plate to the plenum body using at least one of friction welding, welding, mechanically fastening, and press fitting.
