Abstract
A cooling system for an engine having a plurality of piston cylinders. The cooling system can include a liquid coolant source having liquid coolant and a cylinder cooling passage network having an inlet and an outlet for receiving and transmitting the liquid coolant. The cylinder cooling passage network having a plurality of individual upstream fluidic passages each being fluidly coupled to the inlet to directly receive the liquid coolant from the liquid coolant source in parallel flow. The cylinder cooling passage network further having a plurality of cylinder jacket passages each extending about at least a portion of a corresponding one of the plurality of piston cylinders and being positioned immediately adjacent thereto. The cylinder jacket passages are fluidly coupled directly to a corresponding one of the plurality of individual upstream fluidic passages to receive the liquid coolant and transmit the liquid coolant to the outlet for improved cooling performance.
