Abstract
An engine includes a block defining cylinders, a charge-air cooler, and an intake manifold configured to receive air from the charge-air cooler and convey the air to the cylinders. The intake manifold includes an inlet connected in fluid communication with the charge-air cooler, a plurality of runners each associated with one of the cylinders, and a wedge disposed in an air path between the inlet and the runners with a leading edge of the wedge facing the inlet. The wedge is configured to deflect water, condensed in the charge-air cooler, to distribute the water among the runners.
Claims12
An engine comprising:
- a block defining cylinders;
- a charge-air cooler;
- and an intake manifold configured to receive air from the charge-air cooler and convey the air to the cylinders, the intake manifold including:
- an inlet connected in fluid communication with the charge-air cooler, a pair of outer runners and at least one inner runner that are each associated with one of the cylinders, and a wedge disposed in an air path between the inlet and the runners with a leading edge of the wedge facing the inlet, wherein the wedge has a first deflection surface extending from the leading edge towards one of the outer runners such that the first deflection surface is configured to deflect water condensed in the charge-air cooler towards the one of the outer runners and has a second deflection surface extending from the leading edge towards the other of the outer runners such that the second deflection surface is configured to deflect the water towards the other of the outer runners.
An intake manifold of an engine comprising:
- an inlet connectable to a charge-air cooler;
- a common chamber downstream of the inlet;
- a plurality of runners downstream of the common chamber and configured to route air from the common chamber to associated engine cylinders, wherein the runners include a pair of outer runners and at least one inner runner;
- and a wedge disposed in the common chamber in an air path between the inlet and the runners with a leading edge of the wedge facing the inlet, the wedge being positioned in front of the least one inner runner to deflect water, formed in the charge-air cooler, away from the at least one inner runner and towards the outer runners.
An engine comprising:
- a block defining cylinders;
- a charge-air cooler;
- and a cylinder head defining an intake manifold in fluid communication with the charge-air cooler, the intake manifold including:
- a common chamber, a plurality of runners downstream of the common chamber and configured to route air from the common chamber to associated ones of the cylinders, wherein the runners include a pair of outer runners and at least one inner runner;
- and a wedge-shaped water deflector disposed in the common chamber at a location that is front of the at least one inner runner and arranged to deflect water, formed in the charge-air cooler, away from the at least one inner runner towards the outer runners.
