Abstract
A temperature acquisition apparatus for an internal combustion engine is configured to acquire a temperature of a combustion chamber of the internal combustion engine. The apparatus includes: an electronic control unit having a processor and a memory coupled to the processor. The processor is configured to perform: acquiring an intake air amount of the internal combustion engine; calculating a cumulative intake air amount based on the intake air amount; and acquiring a temperature of the internal combustion engine based on the cumulative intake air amount.
