Abstract: Disclosed is an exhaust gas recovery apparatus of an EGR cooler for a vehicle that circulates some of exhaust gases cooled by an EGR cooler to be discharged, not to an engine but to the outside in a low load operation condition or in a winter season condition, and thus maintaining a temperature of engine cooling water high. The apparatus may include a branch pipe for transferring exhaust gases discharged from the EGR cooler to a turbo charger, a flow rate control valve installed in the branch pipe for adjusting a flow rate of the exhaust gases, and a control unit for controlling an opening degree of the flow rate control valve.

Abstract: Disclosed are a thermostat with a failure diagnosis function and methods for diagnosing a failure in a thermostat. The thermostat is to be installed between an engine and a radiator to control cooling water to bypass back to the engine or to circulate to the radiator by means of a valve operated depending on temperatures in the cooling water circulated between the engine and the radiator. The thermostat may include a plurality of water temperature sensors installed before and after the valve to measure the temperatures in the cooling water before and after the valve, for determining whether or not the valve is normally operated by comparing a difference of the temperatures in the cooling water before and after the valve with a preset temperature.

Abstract: An engine system may include an engine configured to generate a torque, a coolant temperature sensor configured to detect a temperature of a coolant circulating the engine, an atmosphere temperature sensor configured to detect an atmosphere temperature, a thermostat disposed on a coolant line to regulate a coolant passage, an operating portion disposed in the thermostat and electrically regulating the coolant passage, and a control portion that variably controls the coolant temperature. The operating portion is operated according to the coolant temperature transmitted from the coolant temperature sensor, the atmosphere temperature transmitted from the atmosphere sensor, and/or an engine load.
