In this paper, the existing methods to reduce the heat discharged by the engine were characterized and the efficiency of combustion piston engine was analysed, where it was shown the need and the potential for reducing the heat dissipated directly or indirectly to the surrounding atmosphere. The model of the engine cooling system for high coolant temperature developed through AMESim software was presented in this paper. The model of the cooling system was made based on test stand solution designed and built using original components and units diesel engine 4CT90. The simulation researches results of temperature course and pressure course were shown. In this paper was demonstrated that it is possible to maintain the assumed constant pressure of 0.3 MPa in the system and obtain it at the elevated liquid temperature leading to an increase in overall engine efficiency. These researches were carried out also on the experimental model stand, which confirmed the results obtained in simulation researches. Then 4CT90 engine test stand was described, where speed characteristics as a function of torque, power and specific fuel consumption and load characteristics as a function of the fractions of hydrocarbons, carbon monoxide and carbon dioxide, as well as specific and hourly fuel consumption were performed. Comparison of parameters and efficiency assessment of engine interacts with a traditional and pressure cooling system. The efficiency of the engine with the pressure and a traditional cooling system was evaluated.
