Number, the integrated informations such as information, the demand of foundation diesel engine of each temperature sensor are gathered, carry out intelligent computing and processing, in fact
Existing data output and power output；Each temperature sensor includes, fuel temperature sensor, exhaust fan at fuel injector
The temperature sensor of air inlet, the fuel temperature sensor of the first petroleum pipeline, the fuel temperature sensor of oil sump tank.
The intelligent control process of control panel is to control the work of electrothermal tube, exhaust fan, 3-position-3-way solenoid directional control valve, is shown
Show the information that diesel engine can start, the information that can be started simply shows that the temperature of fuel oil meets diesel engine
Working performance, without control motor hand work energy.When diesel engine has working signal demand, control panel controls three three
Electric change valve in centre position, is not in the position communicated, oil inlet 12A is communicated with oil outlet 12P or oil inlet 12B goes out
Hydraulic fluid port 12P is communicated.
3-position-3-way solenoid directional control valve normality is in centre position, and Median Function is that two oil inlets of M types communicate, described
Two oil inlets be oil inlet 12A and oil inlet 12B, described two oil inlets are not communicated with oil outlet 12P.
The intelligent control process of control panel 24：
When starting diesel engine, the signal acquisition input system of ECU smart circuit control systems has received start signal, together
When, have received each temperature sensor signal.When the fuel oil temperature that sensor 19 is shown is less than 10 DEG C, storage battery and electric heating are connected
Pipe circuit, makes electrothermal tube work, and generates heat, heats the first petroleum pipeline, makes the temperature rise of the fuel oil in the first petroleum pipeline, when
When fuel oil temperature is increased to 10 DEG C or more, be conducive to flowing, the burning of fuel oil, due to the temperature step of fuel oil temperature transmission process
Difference, when the fuel oil temperature that sensor is shown still is below 10 DEG C；3-position-3-way solenoid directional control valve is controlled in first position, makes the
One petroleum pipeline and fuel filter, 16 unicom state of petroleum pipeline are Fuel Injection Mechanism of Diesel Engine, start diesel engine and work, described first
Position is that oil inlet 12A is communicated with oil outlet 12P, and the fuel oil is the diesel oil of diesel engine；In exhaust fan air inlet
When temperature is higher than 10 DEG C, the work of ECU smart circuits control system control exhaust fan, solenoid valve is opened, and is that oil sump tank and second are defeated
Oil pipe insulating layer blowing hot-air heats the fuel oil in oil sump tank and the second petroleum pipeline；Electrothermal tube is worked at the same time with exhaust fan, and first is defeated
The fuel oil of oil pipe heats simultaneously with the fuel oil in oil sump tank and the second petroleum pipeline.
When showing that the fuel oil temperature of the fuel temperature sensor of oil sump tank is higher than 8 DEG C in ECU smart circuit control systems, control
Making sheet control electrothermal tube is stopped, and exhaust fan works on, ECU smart circuits control system control 3-position-3-way electromagnetic switch
Valve makes the second petroleum pipeline and fuel filter, petroleum pipeline unicom state in the third place, is Fuel Injection Mechanism of Diesel Engine, and diesel engine continues
Work.
When showing that the fuel oil temperature of the fuel temperature sensor of oil sump tank is higher than 75 DEG C on control panel 24, solenoid valve is closed,

Hot wind, control temperature rise, control panel 24 control door leaf to close, by oil sump tank and the second petroleum pipeline insulating layer to oil sump tank and
Second petroleum pipeline is kept the temperature, and slows down working oil temperature decline；The fuel oil temperature of the fuel temperature sensor of oil sump tank is shown on control panel 24
When degree is less than 65 DEG C, control panel 24 controls exhaust fan work, and control panel 24 controls door leaf to open, and is conducive to exhaust fan transmission
Hot air flow is all smooth, is the fuel Heating in oil sump tank and the second petroleum pipeline, and oil temperature raises.
The optimum igniting temperature of diesel oil is 65-75 DEG C, and diesel fuel temperature is increased to 65 DEG C, and fuel consumption can reduce 6-10%, temperature
Low oil-saving effect is poor, can unstable wear, oil-saving effect variation or even the fuel consumption for increasing fuel oil when temperature is more than 75 DEG C.
Control panel 24 controls the course of work of exhaust fan, employs the original of reversed hysteresis output characteristics Schmidt trigger
Reason, it is 75 DEG C to set upper limit threshold temperature, and lower limit threshold temperature is 65 DEG C, and return difference temperature is 75 DEG C-lower limit of upper limit threshold temperature
65 DEG C=10 DEG C of threshold temperature, return difference temperature is 10 DEG C, and exhaust fan is worked, the hot blast pumping of cooling diesel engine is extremely collected
In fuel tank and the second petroleum pipeline insulating layer, heated fuel oil as exhaust fan working condition, the state of exhaust fan is divided into exhaust fan work
Make state and exhaust fan off position.
Principle according to reversed hysteresis output characteristics Schmidt trigger：
(1) the exhaust fans course of work：The fuel oil temperature uphill process that sensor 27 is shown is that the fuel oil temperature of sensor 27 is low
When 65 DEG C, exhaust fan 23 works, and the aperture of air throttle is maximum, and the fuel oil temperature of sensor 27 is from 75 DEG C when being increased to for 65 DEG C
