Abstract
This disclosure generally relates to an oil mitigation system and method for lubricating the piston(s) for electronic fuel injected internal combustion engines, incorporating cylinder deactivation technology. This concept leverages the engine's base fuel injection pulse width table, determines the fuel injection 'shutoff' state and, reduces the oiling to counter the reverse oil flow effect within the cylinder wall, past the ring set to the cylinder combustion chamber. This disclosure further comprises a system and method for mitigating oil consumption to all active cylinders, for accommodating all ranges of engine loading.
