Abstract:
1. A control apparatus for an internal combustion engine comprising: a fuel injection portion that carries out fuel injection for the internal combustion engine; a recirculation portion that recirculates to an intake system evaporative gas of injected fuel that has been mixed with lubricating oil for the internal combustion engine; and circuitry configured to: acquire a fuel mixture parameter corresponding to an amount of fuel that has been mixed with the lubricating oil; acquire a coolant temperature of the internal combustion engine or an oil temperature of the lubricating oil as an engine temperature; perform engine stop control to temporarily stop the internal combustion engine when it is determined that the engine temperature is equal to or higher than a stop permission temperature, using the engine temperature as the stop condition; and raise the stop permission temperature more than usual when the fuel mixture parameter becomes larger than a predetermined reference value, wherein the circuitry reduces an amount of a rise in the stop permission temperature as the fuel mixture parameter increases while remaining larger than the reference value.
