Folksvagen Sharan/Sharan repair>> System of injection of fuel of engine VR6>> Injection system>> The gauge of temperature cooling жидкостси
The gauge of temperature of a cooling liquid represents the resistor which electric resistance changes depending on temperature. The resistor located in the gauge, has negative temperature factor of resistance, i.e. at heating its resistance decreases. The heat of a cooling liquid reduces resistance of the gauge, and low — raises it.
Temperature of cooling liquid ЭБУ counts on a power failure on the gauge of temperature of a cooling liquid. On the cold engine a power failure big enough, and on the heated-up engine — low. Proceeding from the received values, ЭБУ counts duration of an impulse of injection which accordingly will be more at the cold engine, quantity of air in a working mix, an advancing of ignition and idling turns. The temperature of a cooling liquid is used in the majority of functions of engine management.
