In this article has been found that the most popular and widely used method of cooling is liquid cooling, which ensures uniformity of temperature around the combustion chamber and easy acquisition and transfer of heat, although the properties of water are limited by maximum temperature of the coolant. Preliminary scientific research of such a system indicates the possibility of increasing overall efficiency and reducing toxic components in exhaust gases at low engine loads when the engine exhaust temperature of the classic system is too low for efficient catalytic action. This paper presents the dynamometer test stand designed and built using original components of diesel engine 4CT90 production of WSW "ANDORIA" SA. Presented system was designed for the four cylinder with indirect fuel injection system. Research was made on the engine dynamometer stand, which was equipped with standard measure devices (measures: speed, torque, temperatures, flows) and exhaust gas analysers. The temperature of this liquid was increased to the higher level than temperature of boiling water in normal conditions. Overpressure inside the cooling system was limited to 0.3 MPa, the temperature inside the cooling system was increased to 115–120°C. During the test, the cooling system was filled with coolant at 90%. The selected results of investigations of the cooling system for the combustion engine working with higher temperature of the cooling liquid, where the influence of speed and load on the engine temperature were presented.
