Abstract
Methods and systems are provided for a water jacket diverter. In one example, the water jacket diverter has a continuous upper rail with a profile including curved and linear portions where the profile of the upper rail is optimized to moderate coolant flow through the water jacket. The water jacket diverter further includes at least one protrusion extending outwards from an outer face of the diverter, the at least one protrusion positioned in front of a coolant inlet.
Claims19
A diverter for a water jacket, comprising:
- a continuous upper rail arranged around a top periphery of the diverter, above and perpendicular to an inner face and an opposing outer face of the diverter, the upper rail having a profile including both linear portions and portions curving along a cylinder axis of the diverter;
- and
- at least one protrusion extending away from the outer face of the diverter, the at least one protrusion positioned proximate to a coolant inlet flowing coolant into the water jacket,
- wherein the profile of the upper rail includes an uneven and non-uniform arrangement of peaks and wherein the peaks are concave regions of increased height extending above linear portions of the upper rail.
A diverter for a water jacket of a cylinder block, comprising:
- a continuous upper rail forming a top surface of the diverter, the top surface having portions curving along a cylinder axis of the cylinder block, and one or more protrusions extending from an outer face of the diverter, the one or more protrusions having at least one sloped surface, wherein the diverter is configured to be seated within a lower portion of the water jacket to divert coolant to an upper portion of the water jacket above the diverter, wherein a profile of the upper rail varies in shape and a height of the wall of the diverter for each of the plurality of circular sections.
An engine block, comprising:
- a cylinder block with a plurality of cylinders;
- a water jacket disposed in the cylinder block, surrounding the plurality of cylinders and configured to flow coolant through the cylinder block;
- and
- a water jacket diverter seated within a lower portion of the water jacket, the diverter arranged around the plurality of cylinders and having a variable height arising from an upper rail of the diverter, the upper rail having both curved and linear portions, wherein a profile of the upper rail varies in shape and a height of the wall of the diverter for each of the plurality of cylinders.
