PURPOSE: A fluid circuit of an engine is provided to keep proper temperature of oil in an oil circuit connected to an engine and a supercharger by circulating cooing water through a cooling circuit connected to the supercharger. CONSTITUTION: A fluid circuit of an engine comprises a cooling circuit and an oil circuit. The cooling circuit comprises a water pump(10), a radiator(30), a thermostat(40), a first cooling line(50), a first return line(60), a second cooling line(70) and a second return line(80). The water pump is installed in a cooling water circulation line. The radiator is connected to a cooling water discharge line of the engine. The thermostat is connected between the radiator and the water pump and controls the flow of cooling water. The first cooling line connects the cooling water discharge line and auxiliary flow. The first return line connects the auxiliary flow and the thermostat. The second cooling line connects the first cooling line and a supercharger in order to guide a part of the cooling water provided to the first cooling line to the supercharger. The second return line connects the supercharger and the first return line in order to guide the cooling water discharged from the supercharger to the first return line.
