In conventional cooling-circuit, circulation of coolant is carried out with mechanical water pump (MWP), which its rotation speed is a function of engine speed and no feedback of temperature and performance of engine exist. A solution to solve this problem is using electrical water pump (EWP) that its revolution is determined based on coolant temperature. In this research, first coolant circuit of Iranian National Engine was simulated with MWP in GT-Suite software. Warm up time and pressure loss in cooling circuit is validated with experimental data. Then, MWP was replaced with EWP and a Fuzzy controller for determination of EWP speed was designed using Matlab/Simulink environment. The proposed controller was coupled with cooling circuit which designed in GT-Suite and the effect of EWP in cooling circuit on warm up time, was investigated. Simulation result shows 39 percentage reduction of warm up time in comparison with conventional engine.
