AN AUTOMATIC TEMPERATURE CONTROL DEVICE FOR AN INTERNAL COMBUSTION ENGINE

摘要

The present invention relates to a novel device for automatic temperature control in an internal combustion engine of a motor vehicle. More particularly, this invention relates to a motorized water valve driven through the electrical control unit (ECU) wherein the water valve is used to precisely control the engine cylinder at its most efficient temperature. The water valve is used to cool the engine cylinder in condition of high temperature as well as to heat the engine cylinder in condition of cold by precisely controlling through ECU command. The ECU automatically changes the electric command into a hydraulic command which drives the water valve in accordance with the engine cylinder temperature.
