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.

Abstract: A cooling jacket for an engine has upper and lower bodies. The upper body includes a plurality of upper portions. Each upper portion has a top orifice and a bottom orifice. The lower body is located below the upper body and includes a plurality of lower portions. Each lower portion has a lower orifice aligned with a respective one of the bottom orifices so as to permit a coolant to flow through the lower orifice and into the bottom orifice. The coolant flows from that lower portion to the respective one of the upper portions. Each upper portion has at least one upper passageway extending through that upper portion from the bottom orifice to the top orifice so that the coolant entering the upper passageway of that upper portion flows through the upper portion to the top orifice.
