Described heater circuit II includes carbon fiber heating transport pipe V 7, fuel tank concurrent heating delivery line 4 and digital transducer II 5.
Described heater circuit III includes constant temperature streaming separator 8 and digital transducer I 3.
Its working principle is: after connecting single-chip microcomputer temperature controller 9 working powers, the diesel fuel temperature value that single-chip microcomputer temperature controller 9 transmits digital transducer I 3 and digital transducer II 5, compare calculation rapidly, the temperature value that calculates is presented on the screen by display device 10.If digital transducer I 3 and digital transducer II 5 detected temperature digitals are lower than 3 ℃, single-chip microcomputer temperature controller 9 is connected heater circuit I, heater circuit II and heater circuit III working power rapidly, and heater circuit enters heated condition.
The temperature digital that measures as digital transducer I 3 reaches 8 ℃, intrasystem diesel oil has had good flowability (referring to GB 0# diesel oil), diesel engine is unimpeded for fuel pipe, the oil transportation quality has satisfied the cold start-up needs of diesel engine, unnecessary when continuing heating again, single-chip microcomputer temperature controller 9 cuts out the working power of heater circuit I rapidly, and heater circuit I enters armed state, to reduce the consumption of the storage battery energy.
When the temperature digital that measures as digital transducer II 5 reaches 6 ℃, single-chip microcomputer temperature controller 9 will reduce the heating work electric current of carbon fiber heating pipe V 7 and fuel tank concurrent heating delivery line 4 among the heater circuit II gradually, reduce the heating power of carbon fiber heating pipe V 7 and fuel tank concurrent heating delivery line 4 thus.
