摘      要：Thermostat as a part of engine cooling system has a significant role in the shortening warm-up time and regulating the engine in proper temperature to approach optimal ***,there is not adequate research on this part of the cooling system and its *** this gap and also being used in large scale,this study is intended to evaluate performance and reflex of the wax type thermostat in different engine working *** this regard,performance of engine cooling system was investigated in various engine speeds and loads to reveal positive and negative influences of thermostat on engine cooling efficiency and engine *** to observed results,warm-up period and fuel consumption decrease by using a *** the other hand,however,the temperature oscillation of coolant fluid passing through engine increases sharply,which causes a disruption in the regulating engine temperature and also a possibility of the fluid boiling rises in some regions of the engine that increases the risk of damage in the engine *** temperature,fuel consumption,warm-up duration and emissions were provided and compared in two operation modes,with and without thermostat.
