Heat transfer is one of the important issues in internal combustion engines. One of the important aspects in the heat transfer of the engine is the warm-up. The importance of warm-up, especially in terms of pollutant production, has always been of interest to researchers. According to researches, a high percentage of carbon monoxide and hydrocarbon contaminants produced during driving cycles are related to the engine's heating cycle. Therefore, the reduction of warm-up time is always one of the major issues in the field of heat transfer of internal combustion engines. In this study, the use of an electric cooling pump in the cooling circuit is studied as a solution to reduce the engine warm-up time. In this project, a simulation of the cooling circuit with an electric cooling pump with one-dimensional Gt-power software has been addressed and Its influence on the heating of the engine parts during the heating of the engine is examined. In this model, a single-cylinder engine with internal cylinder and cylinder head cooling ports is used. The results show that during the initial period of operation of the engine, the cooling of the engine input could reduce the cooling time of the engine, resulting in faster heating of the components and, consequently, reduced warm-up time.
