ABSTRACT:
This is an improved engine protection device that allows activation of the engine protection device a selected oil pressure and to provide a close pressure for downshifting or shut down to idle. Further, the system may be used to also control the engine speed due to cooling water conditions. The improved device includes an oil pressure regulator having a fluid release system including a reduced pressure feed back system to vary the return pressure to a higher pressure after initial operation at a lower pressure.
