摘要

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 advantages, such as simple structure, safe and rapid heating, and fixed 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 heating effects are also simulated and analyzed. The calculation results show that the diesel temperature is heated by the PTC materials effectively. Meanwhile, the heating law by PTC materials heating diesel fuel in the high pressure fuel pipe of engine is also summarized.
