Description
Technical field
The present invention relates to a kind of a kind of thermosistors of the automobile-used special import arrangement of automobile-used thermostat system more particularly to commercialization
System and its temperature sensing method, it is particularly applicable to realize to the temperature-sensitive of coolant liquid in body, improve temperature-sensitive when partial circulating is closed
Accuracy.
Background technique
Thermosistor arrangement in engine is broadly divided into import arrangement and outlet arrangement, the temperature adjustment arranged using import
The opening and closing of device will not make the temperature of coolant liquid in engine cylinder body generate big fluctuation, when both can ensure that engine cold
Smooth running will not generate fluctuation, and can be shortened the warm-up period of engine.But thermosistor import is arranged, is opened in systemic circulation
Qi Shi, the liquid temperature of perception are the temperature of coolant liquid around thermosistor, these coolant liquids come from radiator, rather than engine cylinder
Body, i.e. body, the temperature that this perceives thermosistor is more relatively low than practical organism temperature, frequently so as to cause thermosistor opening and closing, control
System delay.
