Description
Technical field
The present invention relates to fuel heating system, specially a kind of winter diesel engine fuel oil using waste heat from tail gas heated fuel oil
Heat device for rapidly starting.
Background technology
At present, travelled when diesel vehicle or using the heavy-duty machinery of diesel engine in the environment that outside air temperature is cold, temperature is relatively low
When, it is by fuel Heating, to reach the mobility for improving high grade diesel oil, and ensures the normal startup and operating of diesel engine.
The mode of heating of high grade diesel oil mainly has following several：1st, using electric-heating plug to fuel tank, it is thick consider, it is thin consider with
And whole oil circuit is heated, electric energy used all has storage battery power supply, and oil tank fuel and each several part are heated to pre- by glow plug
After constant temperature degree, engine just can start and operate, but all electric energy, by storage battery power supply, battery needs the work(exported
Rate is big, has larger damage to battery, and in the limited electricity of battery, can not necessarily reach predetermined preheating temperature；2、
Major-minor fuel tank is added, auxiliary fuel tank addition low-grade diesel, realizes and starts, using battery electric energy heating main fuel tank after startup, is treated
After main fuel tank temperature rises, main fuel tank fuel feeding is switched to, is substantially still to be heated using battery, mechanical major-minor fuel tank switching
Engine cold and warm boot can not be differentiated；3rd, at present in a kind of heater of production, be both by based on electric heater unit,
Realize controllable fuel Heating, driver is manipulated by the space of a whole page and reaches control to heating system, needs to wait before activation
Time heats, if outside air temperature, in subzero 30 degrees centigrade, the heat time can be longer.
The content of the invention
The present invention in order to solve existing diesel vehicle start operating using electrical heating exist battery loss is larger, major-minor fuel tank without
Method rationally switches, the heat time is long and the problem of can not reaching preheating temperature, there is provided a kind of winter diesel engine fuel oil heating is fast
Fast starter.
The present invention adopts the following technical scheme that realization：Winter diesel engine fuel oil heats device for rapidly starting, including hair
Motivation, blast pipe, main fuel tank, in addition to auxiliary fuel tank, water tank, single-chip microcomputer, display and oil circuit conversion electromagnetic valve, main fuel tank and
The oil-out of auxiliary fuel tank connects with two inputs of oil circuit conversion electromagnetic valve, the output end and engine of oil circuit conversion electromagnetic valve
Input connection, engine connected with water tank, and cooling-water temperature sensor is provided with water tank, and delivery temperature is provided with blast pipe and is passed
Sensor, fuel temperature sensor, main fuel tank oil pump and the medium temperature core heat pipe connected with blast pipe, auxiliary fuel tank are provided with main fuel tank
Auxiliary fuel tank oil pump and liquid level sensor are inside provided with, direct-acting electromagnetic valve, cooling-water temperature sensor, exhaust are provided with medium temperature core heat pipe
Temperature sensor, the output end of fuel temperature sensor and liquid level sensor and single-chip microcomputer input connection, single-chip microcomputer it is defeated
Go out end to be connected with the input of display, oil circuit conversion electromagnetic valve and direct-acting electromagnetic valve.
Main fuel tank is built with high grade fuel oil, and auxiliary fuel tank is built with low grade fuel oil.
In the winter time, engine cold starts（That is the temperature of exhaust gas temperature sensor, cooling-water temperature sensor and fuel temperature sensor
Degree is below setting value）When, system uses storage battery power supply, now, in the presence of oil circuit conversion electromagnetic valve, auxiliary fuel tank and hair
The oil circuit of motivation is connected, and engine start relies on auxiliary fuel tank fuel feeding, after startup, in the presence of direct-acting electromagnetic valve, and blast pipe
Delivery temperature through medium temperature core adopting heat pipes for heat transfer to main fuel tank, the fuel oil in main fuel tank is constantly heated to exhaust gas temperature sensor with
When the temperature of fuel temperature sensor reaches setting value, under both collective effects, single-chip microcomputer control oil circuit conversion of electromagnetic
Valve events to the oil circuit of main fuel tank and engine is connected, by main fuel tank to engine oil.In whole process, when fuel oil temperature passes
When the temperature of sensor exceedes high critical value, direct-acting electromagnetic valve disconnects, and stops heating, when fuel oil temperature is down under high critical value
When, direct-acting electromagnetic valve is connected；And when cooling-water temperature sensor and exhaust gas temperature sensor reach setting value（There is signal output）
When, single-chip microcomputer preferentially uses the signal of exhaust gas temperature sensor.Engine warm boot（I.e. cooling-water temperature sensor and fuel oil temperature pass
Sensor reaches setting value）When, because exhaust gas temperature sensor is not reaching to setting value, i.e., when no signal exports, passed in water temperature
Under the collective effect of sensor and fuel temperature sensor, single-chip microcomputer control oil circuit conversion electromagnetic valve, make main fuel tank and engine it
Between oil circuit connection, main fuel tank overcomes existing diesel vehicle and starts operating and battery damage be present using electrical heating to engine oil
Consume larger, major-minor fuel tank and can not rationally switch, the heat time is long and the problem of can not reaching preheating temperature.
The present invention has the advantages that：1st, the preheating time of engine can be shorten to zero-waiting from 5-10 minutes,
Quick startup is realized, the time of driver is saved, there is stronger practicality and expansibility；2nd, main fuel tank fuel Heating is fast
It speed, can in minutes bring up on fuel oil condensation point, and optimum ignition temperature can be reached；3rd, it is required without electrical heating
Power is smaller, will not damage battery；4th, relative precombustion chamber glow plug, the system can supply the combustion of steady temperature to combustion chamber
Oil, more convenient, supply resistance is smaller, and atomization, combustion efficiency are more preferable, and then reduces nitrogen oxides and contaminant particle row
Put, meet national energy-saving emission reduction policy；5th, engine can burn high condensation point fuel oil, save a considerable operating cost,
For bulk transport car, 9000 yuan of fuel costs monthly can be about saved；6th, system can realize fully automated control, it is not necessary to drive
Any operation for the person of sailing, avoid the possibility of driver distraction's notice；7th, it is easy for installation, it is only necessary to less to change former car knot
