Control switch is electrically connected with heater controller；Timer respectively with positive pole, heater controller and ground connection
Connection.
Heater control switch (water temperature is less than 68 DEG C) is opened, fan electromotor drives combustion-supporting fan to combustion with relatively low rotating speed
Burner supplies, and after 18 seconds, ignitor starts power supply (electrode power 12 seconds), after 1 second, solenoid valve power supply, electromagnetic fuel pump with
Relatively low frequency is through fuel pipe fuel feeding, if lighting a fire successfully, host enters normal combustion state, while the indicator light that burns switchs to entirely
It is bright, after heater controller judges heater normal fire according to sensor signal, just close ignitor, and make combustion-supporting
Fan and oil pump are respectively with normal rotating speed and frequency air-supply, fuel feeding.When being burned to water temperature and rising to about 81 DEG C, heater stops
Machine, burning indicator light extinguish.After stopping burning, main motor delay working 150 seconds.Water temperature is down to cold-starting temperature (68 DEG C),
Heater is automatically into next working cycles.If ignitor discharges, 12 second ignitions are unsuccessful, after heater is delayed 2 minutes
It lights a fire into second, unsuccessful instruction failure of lighting a fire three times.
By Air-Conditioning Control Panel changes in temperature knob in driver's cabin, heating pattern is selected, rotates air quantity knob, air blower relay
Device is attracted, and air blower is started to work.Cold air is increased through cab heat exchanger operative temperature, rotating control panel scheme control
Knob realizes driver's cabin heating and defrosting-defogging purpose.
Heating plant be will burn generate heat transfer to engine body or driver's cabin in, reach engine warm-up,
Driver's cabin heating and defrosting-defogging effect.It is mainly made of cab heat exchanger, air blower, pipeline, air duct and air port,
It is as shown in Figure 8 to drive indoor heating.
Engine coolant is sent into cab heat exchanger after liquid fuel heating devices heat by pipeline, in air blower
Under the action of by each air port reach to cab compartment heating and defrosting-defogging purpose.Add since engine coolant is recycled
Heat, therefore engine is constantly in by heated condition, this is exactly equivalent to our traditional engine warm-up processes, this
The cold-start performance that the presence of system will greatly promote engine.The more traditional warming-up mistake of warming-up is carried out using fuel heating system
Journey is with the obvious advantage.As do not installed automobile assisted heating device, then be rapid raising coolant in starting process in winter
Water temperature is generally required makes its idle running a period of time after engine ignition, is driven again after water temperature rises to certain temperature, this
Huge injury will be caused to engine, the race of engine will result directly in the discharge of high fuel consumption and pernicious gas.
The utility model has carried out detailed explanation by preferred embodiment.However, by studying carefully above,
Variation and increase to each embodiment are also apparent to those of ordinary skill in the art.It is intended that institute
There are these to change and increase all to fall in the range protected in the utility model claims.
