Description
Technical field
The present invention relates to automobile technical fields, and in particular to a kind of crankcase ventilation pipeline on-off monitoring of structures.
Background technique
Crankcase ventilation system is that the gas entered in crankcase in engine working process is carried out Oil-gas Separation, machine oil
It comes back in oil sump, gas, which enters in admission line, re-starts burning.But in the gas of crankcase ventilation system discharge
Some machine oil are still had in body, if gs-oil separator is interfaced to the disconnection of the pipeline between inlet manifold interface, this part gas
Body will enter atmosphere and pollute environment.
A kind of method of the prior art be monitored by pressure sensor, but it is not only at high cost, but also because
The fluctuation of pressure is smaller, can not carry out superior monitoring.
Summary of the invention
In view of this, the present invention, which provides one kind, can monitor the pipeline that gs-oil separator is interfaced between inlet manifold interface
The crankcase ventilation pipeline on-off monitoring of structures whether disconnected.
In order to achieve the above-mentioned advantages, the present invention provides a kind of crankcase ventilation pipeline on-off monitoring of structures, including gs-oil separator
Interface, inlet manifold interface and air pipeline, air pipeline are made of metal material, and air pipeline includes first end and second
End, first end are socketed on gs-oil separator interface, and second end is socketed on inlet manifold interface, first end and second end electrical connection
To a power supply, air pipeline and power supply form a closed circuit and judge air pipeline if detecting electric current in the closed circuit
Connection is good, if electric current is not detected in the closed circuit, judges that air pipeline disconnects.
Further, the ammeter for detecting electric current is connected in series in the closed circuit.
Further, air pipeline outer sheath is equipped with isolated pipe.
Further, isolated pipe is made of rubber material.
Further, the first binding post, air inlet discrimination are connected between gs-oil separator interface and the first end of air pipeline
The second binding post, the first binding post and the second binding post is connected between interface tube and the second end of air pipeline to connect by harness
It is connected to power supply, air pipeline, the first binding post, the second binding post and power supply form closed circuit.
Further, power supply is provided by electronic control unit, if electric current is not detected in the closed circuit, is controlled electronically
Unit controls engine stop work.
In conclusion since the first end of air pipeline is socketed on gs-oil separator interface, the second end cap of air pipeline
It is connected to inlet manifold interface, first end and second end is electrically connected to a power supply, and air pipeline and power supply form a closed circuit,
If detecting electric current in the closed circuit, judge that air pipeline connection is good, if electric current is not detected in the closed circuit,
Judge that air pipeline disconnects, therefore crankcase ventilation pipeline on-off monitoring of structures through the invention accurate can must monitor ventilation
Whether pipeline disconnects.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of the crankcase ventilation pipeline on-off monitoring of structures of one embodiment of the invention.
Specific embodiment
It is of the invention to reach the technical approach and effect that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Accompanying drawings and embodiments, to a specific embodiment of the invention, structure, feature and its effect, detailed description is as follows.
As shown in Figure 1, the crankcase ventilation pipeline on-off monitoring of structures of one embodiment of the invention includes gs-oil separator
Interface 1, inlet manifold interface 2, air pipeline 3, isolated pipe 4, the first binding post 5 and the second binding post 6.
Air pipeline 3 is made of metal material, including first end 31 and second end 32.First binding post 5 is socketed on oil gas
Detacher interface 1, first end 31 are socketed on the first binding post 5, i.e. the first binding post 5 is connected to gs-oil separator interface 1 and leads to
Between the first end 31 of air pipe line 3.Second binding post 6 is socketed on inlet manifold interface 2, and second end 32 is socketed on the second binding post
6, i.e. the second binding post 6 is connected between inlet manifold interface 2 and the second end 32 of air pipeline 3.Second binding post 6 ground connection.
3 outer sheath of air pipeline is equipped with isolated pipe 4, can play the role of insulation in this way.
First binding post 5 and the second binding post 6 are connected to power supply, air pipeline 3, the first binding post 5, second by harness
Binding post 6 and power supply form closed circuit.In the present embodiment, power supply is provided by electronic control unit, and voltage is 5v or so.
In addition, the ammeter for detecting electric current is also connected in series in the closed circuit, the ammeter and electronic control unit electricity
Gas connection.
If detecting that electric current, the current signal that ammeter will test are sent in the closed circuit by ammeter
Electronic control unit, electronic control unit judge that air pipeline 3 connects well.If not examined in the closed circuit by ammeter
Electric current is measured, electronic control unit does not receive the current signal of ammeter transmission, then judges that air pipeline 3 disconnects or divulges information
Pipeline 3 falls off from interface, and control engine stop work, avoid the gas in air pipeline 3 from disconnecting or falling off into
Enter atmosphere and pollutes environment.
In conclusion since the first end 31 of air pipeline 3 is socketed on gs-oil separator interface 1, the second of air pipeline 3
End 32 is socketed on inlet manifold interface 2, first end 31 and the electrical connection of second end 32 to a power supply, air pipeline 3 and power supply group
At a closed circuit, if detecting electric current in the closed circuit, judge that air pipeline 3 connects well, if in the closed circuit
Electric current is not detected, then judges that air pipeline 3 disconnects, therefore crankcase ventilation pipeline on-off monitoring of structures through the invention can
It must monitor whether air pipeline 3 disconnects with accurate.
