Abstract:
1. A method for controlling an amount of heat generated in an internal combustion engine, the method comprising: detecting, with a detector, estimation factors including a refrigerant temperature of a refrigerant in an exhaust-system cooling means that cools an exhaust system of an internal combustion engine by the refrigerant, an intake air temperature of the internal combustion engine, a number of revolutions of the internal combustion engine, and an intake air amount of the internal combustion engine; estimating, with a controller, an amount of heat which the refrigerant receives from an exhaust on the basis of a value obtained by a product of a sum of the refrigerant temperature and the intake air temperature, the number of revolutions and the intake air amount, and controlling, with the controller, based on the estimate of the amount of the heat, the amount of the heat or a radiation of heat from the refrigerant.
