| 主权项 | 1. An engine system having a thermostat, the engine system comprising: a thermostat casing that has one side connected to a first flow channel, the other side connected to a second flow channel, and a wall between the one side and the other side connected to third and fourth flow channels; a valve guide in which a main valve that opens and closes the first flow channel is formed at one side, a closing valve that opens and closes the second flow channel is formed at the other side, and a bypass valve is formed adjacent to the closing valve; an elastic member that elastically supports the valve guide to enable the main valve to block the first flow channel and the closing valve to block the second flow channel; a driver that moves the valve guide so that the main valve opens the first flow channel and the closing valve opens the second flow channel according to a temperature of a coolant; and a control unit that controls the temperature and a flow of the coolant by controlling the driver, wherein the first flow channel is a radiator exhaust flow channel that is connected to a radiator, the second flow channel is an engine exhaust flow channel that is connected to one side of an engine, the third flow channel is an engine inflow flow channel that is connected to the other side of the engine, and the fourth flow channel is a heater exhaust flow channel that is connected to a heater. | ||
