2.7.7.10. Sensor of temperature of cooling liquid

The sensor of temperature of cooling liquid is installed in the pipeline of cooling liquid on a head of cylinders. The sensor is executed in the form of a thermistor which resistance changes depending on temperature of cooling liquid. Resistance of the sensor decreases in process of liquid temperature increase. The control unit of the engine receives signals from the sensor and on the basis of this information regulates duration of the managing directors of impulses given on nozzles and a corner of an advancing of ignition. On a measure temperature increase of EBU liquid reduces amount of injectable fuel and a corner of an advancing of ignition.
