The article discusses the problem how forced air flow is implemented through the cooling module of heavy-duty engines. The kinematic connection between the coolant pump and the crankshaft of the engine, results in the fact that the pump performance often does not correspond to the engine demand at its part load. In conjunction with the fan drive method, the temperature of the coolant may be too low or too high for part load. The study was carried out in order to calculate the parameters of the cooling system in heavy-duty engines for maximum power and maximum torque, taking into account a mechanical fan drive, a hydraulic fan drive and an electric fan drive.
