THERMOSTAT WITH FAILURE DIAGNOSIS FUNCTION AND MEHOD FOR FAILURE DIAGNOSIS OF THERMOSTAT USING THE SAME |
| 摘要 |
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. |
