【 摘 要 】

The study discusses the influence of the type of drive used in city buses on the elements and parameters of the cooling system operation. Currently, commonly used are the combustion engines powered by diesel fuel and, to a lesser extent, combustion engines powered by natural gas. However, due to air pollution in cities, measures are taken to reduce vehicle emissions. Consequently, city hybrid or electric buses are developed. In all systems there are losses generating heat, which has to be removed. However, the amount of heat varies depending on the type of drive system and, more importantly, also greatly varied is the permissible operating temperature of the drive components, what results in the need to use different solutions of cooling systems. The study is an analysis of cooling system operation parameters for individual drive solutions and the solutions necessary to meet these parameters are presented.
