Control system of a device for the cooling of an internal combustion engine

摘要

The invention relates to a control system of a device for the cooling of an internal combustion engine with a coolant temperature sensor and a fan. The invention is characterised by the following features: - means for the detection of engine parameters for sensing the engine; - first means of comparison between a temperature value (Tf) measured by the sensor and a predetermined upper temperature limit (Tfs); - means which control the adjustment of the value of some engine parameters when the first means of comparison detect that the temperature value (Tf) measured by the sensor is greater than the upper temperature limit (Tfs); - means of triggering operation of the fan when the said temperature value (Tf) measured by the sensor is greater than the upper temperature limit (Tfs); - second means of comparison between a temperature value (Tf) measured by the sensor and a predetermined lower temperature limit (Tfi); - means which re-establish the values of the parameters when the second means of comparison detect that the temperature value (Tf) is smaller than the lower temperature limit (Tfi) and - means of blocking the operation of the fan when the temperature value (Tf) is smaller than the lower temperature limit (Tfi).
