Abstract:
1. A control device for an internal combustion engine, comprising: an exhaust manifold connected to the internal combustion engine; a cooling unit arranged on a path where a coolant is circulated, the cooling unit being configured to cool an exhaust gas flowing through the exhaust manifold from the internal combustion engine with the coolant flowing through the cooling unit, the cooling unit being attached with the exhaust manifold; a heat quantity estimation portion configured to estimate a heat quantity, in the cooling unit, transferred from the exhaust gas flowing through the exhaust manifold to the coolant flowing though the cooling unit; an atmosphere pressure detection portion configured to detect an atmosphere pressure; and an engine control portion configured to: correct the decision value to be lower as the atmosphere pressure is lower; perform the exhaust gas temperature control for suppressing the temperature of the exhaust gas when the heat quantity is more than the decision value.
