  • Oil cooled internal combustion engine
    Patent number: 4440118
    Abstract: An oil cooled system for an internal combustion engine (2 and 2') includes a cylinder liner (22 and 22') shaped to form an annular oil flow passage (36 and 36') by an inner flow control surface (52 and 52') and outer flow control surface (56 and 56') through which engine lubrication oil flows in a very thin film under laminar flow conditions to produce a very large convective heat transfer coefficient of 300-400 BTU's per hour-feet squared-degree Fahrenheit. To insure laminar flow conditions, the radial thickness of the annular flow passage (36 and 36') is held to less than 0.016 inches and is preferably in the range of 0.008 to 0.010 inches.
