The principle of the present invention is described as follows:
For promoting the industrial competition of our company automobile, in fuel oil supply system, install heating system additional, with solve diesel engine-
20 DEG C, to the cold start-up under the low temperature environment of-30 DEG C and the problems such as frozen block of catching a cold of fuel system, are improved the service efficiency of fuel oil,
Widen the range of fuel oil label, extend diesel engine service life, to adapt to north cold area and season, meanwhile, for solving
Certainly accumulator feeding and cause the problem that motor starting characteristic is poor, reliability is low, the design provides a kind of fuel Heating intelligent
Control system and control method thereof；Being computed, heater power is up to 800W, if using 0 diesel oil when temperature as little as-30 DEG C,
Then can cause accumulator feeding because heat time heating time is long, thus affect electromotor and start, therefore the double fuel tank scheme of design, main oil
Case uses high grade diesel oil, and auxiliary fuel tank uses low-grade diesel, and auxiliary fuel tank is a little fuel tank, is mainly used in starting electromotor,
When main fuel tank inlet port temperature being detected less than 5 degrees Celsius, fuel Heating controller controls major-minor fuel tank switching valve by oil circuit
Switch to auxiliary fuel tank loop, now, rely on auxiliary fuel tank to start electromotor, after electromotor starts, when rotating speed reaches 700rpm, combustion
Oil heating controller controls the coil-end energising of relay, the tip side adhesive of relay, and six heaters are started working, heating
Main fuel tank oil piping system, when detecting that main fuel tank inlet port temperature reaches 25 DEG C, fuel Heating controller detects that temperature control is opened
Closing and disconnect, now, stop heating, fuel oil switches to main fuel tank loop；When driver is to be stopped, within 35 minutes in advance, close fuel oil
Heater switch, now, fuel Heating controller control major-minor fuel tank switching Vavle switching oil circuit is to auxiliary fuel tank loop, to ensure to stop
Front car load oil circuit is all low-grade diesel oil, thus ensures upper electric energy normal starting electromotor next time.
Fuel tank heater be fuel heating system basic configuration (in the design, main fuel tank heater is Resistant heating,
Maximum heating power 250W, band temperature detect switch (TDS), the high prosperous great achievement in Beijing produces), early stage, when carrying out verification experimental verification, finds environment temperature
Spend the impact on fuel Heating very big, if ambient temperature is the lowest, such as subzero less than 20 DEG C, after fuel oil heats in fuel tank,
During entering electromotor, being still likely to occur owing to ambient temperature is the lowest, oil inlet pipe intermediate fuel oil viscosity is big affects electromotor
Situation about starting；The design adds heater for oil tube, and (three oil pipes of heater heating are all oil inlet pipes, because fuel oil passes through
After electromotor, temperature is the highest, it is not necessary to reheat, so being only mounted with heater at oil inlet pipe, heater for oil tube is electricity
Resistance silk heating, heating power is relevant with tubing length, and rated power is 12 18W m, band temperature detect switch (TDS), and the high prosperous great achievement in Beijing is raw
Produce), heater for oil-water separator (Resistant heating, maximum heating power 200W, band temperature detect switch (TDS), Shanghai Fleetguard produce),
Electromotor fine filtering heater (Resistant heating, maximum heating power 250W, band temperature detect switch (TDS), Shanghai Fleetguard produces), it is ensured that
The heating of the whole in-line of high grade diesel oil, Reliable guarantee electromotor normal starting；Meanwhile, each heater in the design
All being controlled by a temperature detect switch (TDS), when fuel oil temperature is less than 5 DEG C, temperature detect switch (TDS) turn on automatically, when fuel oil temperature reaches 25 DEG C
Time, temperature detect switch (TDS) disconnects, and stops heating, it is to avoid the locally too high generation causing accident of heating-up temperature.During fuel Heating,
The fuel Heating display lamp being arranged in combination instrument controller lighted by fuel Heating controller rigid line.
