System for cooling engine of mild hybrid vehicle and method for cooling engine of mild hybrid vehicle

摘要

A system for cooling an engine of a mild hybrid vehicle includes an engine that includes a plurality of combustion chambers generating driving torque by combustion of a fuel, an integrated starter-generator, a clutch that selectively transmits the driving torque to a transmission, a driving information detector that detects driving information of the vehicle, a cooling line through which a coolant for cooling the combustion chamber flows, a heat storage tank disposed at the cooling line, and that temporarily stores the coolant, and a controller that controls an inflow coolant amount flowing in the heat storage tank and an exhaust coolant amount exhausting from the heat storage tank depending on the driving information of the vehicle detected by the driving information detector.
