Abstract:
A control module and method for controlling an engine operation includes a runtime module that determines a previous run period, a fuel mass module that determines a fuel mass during the previous run period, a spark fouling condition estimation module that determines a spark fouling condition based on the fuel mass during the previous run period and an engine operation module that controls the engine in response to the spark fouling condition.
