Abstract
An internal combustion engine includes: an exhaust heat collector, in which exhaust gas exchanges heat with engine coolant, that heats the engine coolant; an EGR mechanism that recirculates a part of the exhaust gas to an intake passage through an EGR passage that branches from an exhaust passage; and an EGR cooler that cools the exhaust gas flowing through the EGR passage through heat exchange with the engine coolant supplied from the exhaust heat collector.
