US Patent 10480439 System and method for mitigating wet-fouling of spark plugs

Methods and systems are provided for mitigating spark plug wet-fouling in an engine system. In one example, a method may include, after spark plug wet-fouling has been detected prior to an engine start, selecting between drying one or more of the wet-fouled spark plugs by routing a heated gas through one or more engine cylinders and by routing a compressed gas through the one or more engine cylinders. In this way, on-demand airflow may be provided to expedite spark plug drying.
