Description
Technical field
Automotive inspection equipment technical field is the utility model is related to, more particularly to a kind of engine intake and exhaust system air-tightness
Detection means.
Background technology
During automobile inspection, automobile test, the air-tightness of the air inlet system and exhaust system of vehicle motor is experiment effectiveness
Necessary guarantee condition.In the past by starting engine, come the air-tightness for air inlet system and exhaust system of checking.This method had both been brought dangerous
Factor, and the noise after engine start can cover part gas leakage sound, and leakage detection gas effect is unsatisfactory.
Utility model content
In view of the deficienciess of the prior art, main purpose of the present utility model is to provide a kind of peace for ensureing engine
It is complete and can quick and precisely detect the detection means of engine intake and exhaust system air-tightness.
To achieve the above object, the utility model provides following technical scheme：A kind of engine intake and exhaust system is airtight
Property detection means, including engine, EGR valve is provided with the engine, the engine includes inlet end and exhaust end,
The inlet end is connected with pressure gauge, and the pressure gauge is connected with respirator, and the exhaust end is connected with plug, and the plug connects
Tracheae is connected to, the tracheae is connected with pressure controller, and the pressure controller is connected with compressed air cylinder by tracheae.
Preferably, the inlet end of the engine and exhaust end are provided with suds flusher.
Preferably, several shower nozzles are provided with the suds flusher.
The utility model has the following advantages that relative to prior art, a kind of engine intake and exhaust system of the present utility model
The operation principle of air-tightness detection device is to connect pressure gauge and respirator in the inlet end of engine first, connect in exhaust end
Plug, pressure controller and compressed air cylinder are connect, then opens EGR valve, compressed air cylinder starts to supply, and utilizes pressure control
Device processed controls in-engine air pressure at any time.Then the pressure gauge of inlet end is observed, passes through gas leakage sound, and sprinkling suds
To check the air-tightness of air inlet system and exhaust system.The present apparatus can arbitrarily control compressed air as needed by adjusting pressure controller
Pressure, engine noise is avoided to influence, so that the work of leakage detection gas becomes simple, efficient.Avoid too high pressure pair simultaneously
Damage caused by engine interior.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of engine intake and exhaust system air-tightness detection device, including engine 1, the engine 1
On be provided with EGR valve 4, the engine 1 includes inlet end 2 and exhaust end 3, and the inlet end 2 is connected with pressure gauge 5, institute
State pressure gauge 5 and be connected with respirator 6, the exhaust end 3 is connected with plug 7, and the plug 7 is connected with tracheae 8, the tracheae 8
Pressure controller 9 is connected with, the pressure controller 9 is connected with compressed air cylinder 10 by tracheae 8.
A kind of operation principle of the air inlet system and exhaust system air-tightness detection device of engine 1 of the present utility model is to send out first
The inlet end 2 of motivation 1 connects pressure gauge 5 and respirator 6, and plug 7, pressure controller 9 and compressed air are connected in exhaust end 3
Tank 10, EGR valve 4 is then opened, compressed air cylinder 10 starts to supply, and is controlled at any time in engine 1 using pressure controller 9
Air pressure.Then the pressure gauge 5 of inlet end 2 is observed, the gas of air inlet system and exhaust system is checked by gas leakage sound, and sprinkling suds
Close property.The present apparatus can arbitrarily control compressed air pressure as needed by adjusting pressure controller 9, avoid the noise of engine 1
Influence, so that the work of leakage detection gas becomes simple, efficient, cost is low.Too high pressure is avoided to being made inside engine 1 simultaneously
Into damage.
Preferably, the inlet end 2 of the engine 1 and exhaust end 3 are provided with suds flusher 11.Realize certainly
Dynamic sprinkling suds, rapidly and efficiently.
Preferably, several shower nozzles 12 are provided with the suds flusher 11.Shower nozzle 12 can uniformly spray
Suds, if gas leakage, visual effect are apparent.
Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
