Hydrostatic-lock occurs when an incompressible fluid replaces air entering an internal combustion engine. As the piston attempts to compress the fluid, the engine will stall, potentially resulting in the failure of various components. Analysis of engine dynamics led to the development of two systems, which sought to mitigate and prevent hydrostatic-lock conditions .The first system measures pressure in the engine's intake, If a negative pressure spike is detected, indicating filter submersion, the intake is closed off. Should water enter the combustion chamber, the second system, a valve in the engine head, will release, relieving excess pressure. Following computer simulation, a prototype of each system was manufactured and validated through testing.
