Specific embodiment
The illustrative embodiments of the disclosure are more fully described below with reference to accompanying drawings.Although showing this public affairs in attached drawing
The illustrative embodiments opened, it being understood, however, that may be realized in various forms the disclosure without the reality that should be illustrated here
The mode of applying is limited.It is to be able to thoroughly understand the disclosure on the contrary, providing these embodiments, and can be by this public affairs
The range opened is fully disclosed to those skilled in the art.
Fig. 1 is the whole interior structural schematic diagram of the utility model embodiment.As shown in Figure 1, being used in the present embodiment
The automatic draining cup of low pressure fuel system, including cup ontology 10.Water level sensor 20, water are equipped in cup ontology 10
Level sensor 20 is equipped with probe 21, and the bottom of cup ontology 10 is additionally provided with for being connected to 10 inside of cup ontology and drainpipe 40
Solenoid valve 30, when solenoid valve 30 it is in the conductive state it is lower ponding in cup ontology 10 can be discharged by drainpipe 40,
Electromagnetism valve position sensors 50 are additionally provided on solenoid valve 30.
In the present embodiment, when ECU detects that the revolving speed of engine is zero, and water level sensor 20 detects cup ontology
There are when ponding in 10, control solenoid valve 30 is connected.Solenoid valve 30 carries out the work that discharges water, water according to the working time that ECU is set
Ponding in cup ontology 10 is discharged by drainpipe 40.After the completion of discharging water, ECU controls solenoid valve 30 and closes.Solenoid valve position at this time
It sets sensor 50 and judges the location information of solenoid valve 30, and will test signal and pass to ECU, ECU is according to solenoid valve position sensing
The detection signal of device 50 judges whether solenoid valve 30 closes.Solenoid valve 30 in the present embodiment is set as be powered conducting, power-off pass
The state closed.If detecting that solenoid valve 30 is not off, ECU controls solenoid valve 30 again and executes movement on and off,
At most three times.If electromagnetism valve position sensors 50 detect that solenoid valve 30 is still not turned off, ECU quotes solenoid valve 30 and event occurs
