The utility model relates to an engine cold starting auxiliary system with changed time sequence, comprising a controller, a preheating electromagnetic valve, a preheating plug, a water temperature sensor, a preheating indicator light, a relay and a switch. The controller is connected with the preheating electromagnetic valve, the preheating plug, the water temperature sensor, the preheating indicator light, the relay and the switch. The engine cold starting auxiliary system with changed time sequence is characterized in that the controller is a programmable controller capable of changing the cold starting time sequence, and the programmable controller ensures that the preheating electromagnetic valve can be electrified in advance before electrifying a starting motor. The utility model adopts the programmable controller and ensures that the preheating electromagnetic valve can be connected in advance through changing the time sequence of cold starting.
Description
Technical field
The utility model relates to a kind of engine cold starting auxiliary system that changes sequential.
Background technique
When motor is used for areas such as high and cold, plateau, cold start aid is a kind of requisite device of motor, and the flame pre-heating system is a kind of as the cold starting ancillary method, and its application is very extensive.General its sequential chart of flame pre-heating system all is that starting electrical machinery, solenoid valve are switched on simultaneously, but under the situation of battery voltage deficiency, because starting electrical machinery is robbed electricity, causes solenoid valve to open difficulty, influences the cold starting effect.
Summary of the invention
The utility model switched on, avoids actuating motor to rob the engine cold starting auxiliary system of the change sequential of electricity to pre-thermoelectrical magnetic valve for the technical problem that exists in the solution known technology provides a kind of before the starting electrical machinery energising in advance.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of engine cold starting auxiliary system that changes sequential, it comprises controller, pre-thermoelectrical magnetic valve, heater plug, cooling-water temperature sensor, pre-thermal light, relay and switch, be connected with pre-thermoelectrical magnetic valve, heater plug, cooling-water temperature sensor, pre-thermal light, relay and switch on the controller, it is characterized in that: described controller is for changing the programmable controller of cold start-up sequential, and this programmable controller makes gave pre-thermoelectrical magnetic valve energising in advance before the starting electrical machinery energising.
Advantage and the good effect that the utlity model has are: owing to adopted the programmable controller that can change sequential, make and before the starting electrical machinery energising, give pre-thermoelectrical magnetic valve energising in advance, rob the problem that electricity preheating solenoid valve is opened difficulty with regard to having avoided because of starting electrical machinery like this.The utility model also has simple in structurely in addition, and cost is low, is easy to advantages such as popularization.

Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-3, a kind of engine cold starting auxiliary system that changes sequential, it comprises programmable controller 1, pre-thermoelectrical magnetic valve MV, heater plug P, cooling-water temperature sensor Rt, pre-thermal light DL, relay K, preheating switch ON shelves K1 and preheating switch ST shelves K2, and pre-thermoelectrical magnetic valve MV, heater plug P, cooling-water temperature sensor Rt, pre-thermal light DL, relay K, preheating switch ON shelves K1 are connected with programmable controller 1 respectively with preheating switch ST shelves K2.
Connect preheating switch ON shelves K1, cooling-water temperature sensor Rt at first measures engine water temperature, if engine water temperature is higher than 0 ℃, pre-thermal light DL extinguishes after bright 2 seconds, and Preheating unit is not worked.If engine water temperature is lower than 0 ℃, pre-thermal light DL is bright, and heater plug P energising heats up.Preheating is in the time of 20 ± 2 seconds, and pre-thermoelectrical magnetic valve MV connects, and has the oil of a small amount of low speed to flow to heater plug P.(change with battery tension preheat time) pre-thermal light DL goes out after 26 ± 2 seconds, and this moment, heater plug P end was red-hot, and temperature is up to more than 900 ℃.Connect preheating switch ST shelves K2, pre-thermal light DL lights again, and diesel oil forms flame in heater plug P internal combustion, and air inlet is heated.More than whole process all control by programmable controller 1.After starting is finished, can enter the back warm-up phase, to reach the warming up purpose according to client's needs.Back preheat time, length was different and different with engine water temperature.
Before changing sequential, because starting electrical machinery and pre-thermoelectrical magnetic valve MV switch on simultaneously, cause starting electrical machinery and pre-thermoelectrical magnetic valve MV to rob electricity, pre-thermoelectrical magnetic valve MV voltage is lower, opens difficulty, therefore causes the cold starting difficulty.After changing sequential, consider pre-thermoelectrical magnetic valve MV cut-in voltage to have relatively high expectations and to keep voltage relatively low, avoided actuating motor to rob the phenomenon of electricity in advance before the starting electrical machinery energising pre-thermoelectrical magnetic valve MV energising, pre-thermoelectrical magnetic valve MV can open smoothly, has therefore improved cold starting performance.
