Abstract
Various thermal energy management strategies and energy efficiency researches are carried out in internal combustion engines. For this purpose, in this study, a kind of thermal energy management strategy regarding the application of coolant flow rate control in the engine cooling system has been investigated. In the thermal energy management strategy approach, the experiments were carried out on a gasoline-fueled spark-ignition test engine under different engine load and continuously variable speed conditions. An electric pump is integrated into the system, which can be switched on as needed to ensure a controlled flow of coolant. A total of four different configurations were tried on the engine cooling system, including a mechanical pump and an electric water pump integrated.6.2% and 5.34% improved. In addition, energy balance and engine performance characteristics analyzes were made during the warm-up phase of the engine and it was seen that the EPICS strategy had positive effects on engine efficiency and CO exhaust emissions. With the EPICS strategy, the specific fuel consumption under different loads improved by 7.72% and 5.2%, respectively. Thus, the benefits of the coolant control strategy applied in variable speed operating conditions are examined in detail.
