| Abstract: | The PTC materials,as a kind of positive temperature coefficient materials,are used to heat diesel fuel in the high-pressure fuel pipe near the injector in diesel engine,which have a lot of characteristics,such as simple structure,safe and rapid heating,and stable heating temperature around its curie point.In order to study its heating effect on diesel fuel of the high pressure fuel pipe,the dynamical models for both the controlled object and PTC heater are presented by the way of lumped parameter,and the he... |
