Abstract
A coolant jacket for an engine cylinder bank having longitudinally aligned cylinders includes upper, lower and side walls defining two inlet flow galleries extending along the intake and exhaust sides of the cylinder bank and communicating with the upper ends of the cylinders. Two outlet flow galleries extend along the intake and exhaust sides of the cylinders and communicate with the lower ends of the cylinders and pairs of side flow slots extend between the upper and lower galleries and around the intake and exhaust sides of each of the cylinders. The side flow slots are separated along longitudinal edges from the slots of adjacent cylinders. Preferably, cooling fins extend into the flow galleries, forming pockets at the ends of the flow slots, the fins being impacted by coolant flow directed into the pockets to improve cooling of siamesed portions of the cylinders. Additional features are disclosed.
