  • Publication number: 20090107770
    Abstract: A method and system for detecting fugitive fueling arising from a pressure-lubricated air inlet system component, such as a turbocharger, within an internal combustion engine includes monitoring lubricating oil pressure within at least one location within the lubrication circuit of the engine and comparing the monitored oil pressure with the failure range contained within a component failure template. If the monitored oil pressure lies within the failure range of the component failure template, remedial action will be taken to mitigate engine damage caused by oil entering engine cylinders from the failed component.
