LINER COOLANT FLOW PILOT FEATURE

The application relates to a liner coolant flow pilot feature. A coolant liner includes a first flow surface to direct coolant fluid toward the cylinder and a transition region coupled to the first flow surface. The transition region includes a convex portion having a first radius of curvature and a concave portion having a second radius of curvature. The concave portion is coupled to the convex portion at an inflection point. A second flow surface is coupled to the transition region to direct coolant fluid around the cylinder.
