Abstract
Systems, devices, and method are disclosed for differentially cooling an internal combustion engine. A cooling system includes a first cooling circuit configured to lower a temperature of a cooling fluid to a first temperature where the first cooling circuit is configured to dispense a first portion of the cooling fluid to cylinder walls and non-cylinder or non-combustion surfaces of the engine. The cooling system also includes a second cooling circuit configured to lower the temperature of a remaining or second portion of the cooling fluid to a second temperature that is lower than the first temperature where the second cooling circuit is configured to dispense the remaining portion of the cooling fluid to cylinder or combustion surfaces within one or more cylinders of the internal combustion engine.
