Flow, when the first pulse pump 100 works, you can passed through by the fuel of small flow, in this way, passing through the fuel of small flow
It realizes and completes igniting, it can also be by the continue working of the first pulse pump 100 of small flow, to ensure the water temperature in water circulation system
Certain temperature is may remain in, heater sustained combustion is made.
On the basis of the above embodiments, further, it is respectively arranged on first oil circuit and second oil circuit
First throttle valve and second throttle.
In the present embodiment, it is also respectively provided with first throttle valve and second throttle on the first oil circuit and the second oil circuit,
In this way, can also be adjusted by the flow of the fuel in first throttle valve and the first oil circuit of second throttle pair and the second oil circuit
Control can be adjusted when heater needs quickly to improve the water temperature in water circulation system by adjusting the first regulating valve and second
The output quantity of first oil circuit and the fuel of the second oil circuit is adjusted section valve.
A kind of automobile has above-mentioned heater.
A kind of automobile provided by the invention has above-mentioned heater.Its advantageous effect and heater compartment for generating, no
It repeats again.
The specific works step of heater:
A) the heater starting stage
Control device receives enabling signal, and glow plug 312 works, and supply fan starts operating.First pulse pump 100 opens
Dynamic, methanol is rapidly reached ignition concentration by atomizer 311, improves under traditional mode, the first caused by the volatilization time is longer
Alcohol leaks.Controller controls the state of the second pulse, if loss of ignition, first according to the flame information that flame sensor senses
Pulse pump 100 works on until lighting a fire successfully.If lighting a fire successfully, the second pulse pump 200 starts, and glow plug 312 stops work
Make, the starting mode of pump in water circulation system, the first pulse pump 100 is stopped.
B) heater stationary operational phase
The water temperature signal that controller is transmitted according to temperature sensor controls the first pulse pump 100 and the second pulse pump 200
State, the second pulse pump 200 work always, until reaching one preset value of temperature control, the first pulse pump 100 starts, the second pulse
Pump 200 is closed.Heater burns away, and 310 remaining methanol of consumption volatilizer reduces under traditional mode, volatilizer 310 is remaining
The leakage of methanol improves the utilization rate of fuel.310 residual methanol after-flame of device to be evaporated, the first pulse pump 100 are closed.Until water
Temperature sends out enabling signal again down to the second preset value, controller.
C) heater shutdown phase
Device sending and receiving processed go out stopping signal, and the first pulse pump 100 starts, and the second pulse pump 200 is stopped, and consumes volatilizer
310 residual methanols, the first pulse pump 100 are closed, and heater is shut down.
