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.
