In cold start driving cycles, the use of the electric water pump and variable flow oil pump for diesel engine saves fuel and reduces emissions. The electric water pump and variable flow oil pump allow the engine coolant and lubricant system to select the optimized operation condition. In this study, electric water pump and variable flow oil pump are designed for engine warm up system based on GT-Suite simulation. Also, the designs are compared based on the practical flow and temperature conditions of WLTP driving cycle.
