Abstract: This paper illustrates the differences between mechanical and electrical water pumps of internal combustion engines. Literatures have been studied in regard to engine cooling with the water pumps. Main design features of the mechanical and electrical water pumps have been illustrated. Engine dyno tests have been performed to evaluate if increased torque and power can be obtained in a common internal combustion engine (ICE) fitted with an electric water pump. Experiments were conducted to verify the effectiveness of an electrical pump over a standard mechanical pump.

Keywords: power; torque; electrical water pumps; mechanical water pumps; oil temperature; water temperature; cylinder wall temperature; pump performance; internal combustion engines; ICE; engine cooling.
