Abstract
Systems and devices are disclosed for controlling fluid flow to piston cooling nozzles with a fluid flow control device configured to open when an internal combustion engine requires piston cooling at high speed but remains open for a period of time after the engine speed drops below a threshold to prevent heat soak damage to the pistons.
