Gas manifold burns again.When engine works, the generation of some gas blowby is understood, gas blowby includes unburned mixture, vapor and gives up
Gas, engine load is bigger, and the gas blowby of formation is more.Gas blowby, which enters oil sump, can dilute machine oil, accelerate machine oil oxidation and go bad,
Cause machine oil hydraulic performance decline；Sour gas enters lubricating system in gas blowby, easily leads to parts corrosion.In extremely cold climatic environment
Under, when engine load increases, the gaseous mixture of crankcase is sealed in out of cylinder to be increased, and gas blowby enters by exhaust gas snorkel to be started
Machine inlet end.During full engine load, at exhaust gas venting tube outlet, meet with the cold gas in engine air inlet tube, easily
The position in snorkel is caused to freeze.When vehicle is continuously run, freezing can be increasingly severe, may block exhaust gas snorkel.One
Denier exhaust gas is ventilated blockage, and gas blowby of the vehicle still in high-speed cruising, crankcase can not be discharged in time, crankcase pressure by
Edge up height, causes oil rule pop-up or crankshaft rear oil seal oil leak.It ultimately results in machine oil and excessively high, insufficient lubrication, damage hair is lost
Motivation.
The existing conventional solution for the problem：In the position that crankcase waste gas snorkel and engine intake cross
It puts and installs circuit kit heating unit additional, ECU is outputed signal to by environment temperature sensor, ECU judges, and exports control letter
Number, by way of connecting heating resistance wire heating, crankcase waste gas snorkel is made to keep suitable with engine air inlet tube river conjunction
Work as temperature, solve the problem of that engine exhaust gas snorkel under extremely cold climatic environment freezes with this, ensure that vehicle is reliably transported
Row.It is had the disadvantage that using the program：1st, the electronic components such as use environment temperature sensor, heating resistance wire, and need to carry out
Software development, input cost are high；2nd, increase control harness arrangement, easily generate interference with its Surrounding Parts；3rd, heating resistance wire exists
Battery consumption electric energy in the course of work influences the economy of vehicle.Therefore, it is necessary to develop a kind of anti-freeze crankcase ventilation
System pipeline structure.
The content of the invention
The purpose of this utility model is to provide a kind of anti-freeze crankcase ventilation system pipeline structure, can effectively prevent
Only crankcase ventilation system freezes, and simple in structure, and arrangement is convenient.
Anti-freeze crankcase ventilation system pipeline structure described in the utility model, including exhaust gas connection for breather pipe and hair
Motivation cooling water pipe connector；Described exhaust gas connection for breather pipe one end is connected with triton hose, and the other end connects with air filter air outlet pipe

It connects；The cooling water pipe of engine connector is "u"-shaped, and bending section semi-surrounding exhaust gas connection for breather pipe utilizes engine
High-temperature water heating exhaust gas connection for breather pipe in cooling water pipe connector.
Further, the cooling water pipe of engine connector with exhaust gas connection for breather pipe in semi-surrounding position by welding phase
Even.Using welding manner so that the connection of cooling water pipe of engine connector and exhaust gas connection for breather pipe is more stablized, the company of improving
Connect reliability.
Further, one end that the exhaust gas connection for breather pipe is connected with triton hose is equipped with positive stop lug boss, goes out with air filter
One end of tracheae connection is equipped with the first anti-dropout component.
Further, the cooling water pipe of engine connector both ends are equipped with the second anti-dropout component.
Further, between the exhaust gas connection for breather pipe and air filter air outlet pipe by the first clamp connection, engine is cold
But water pipe head passes through the second clamp connection with engine cooling water water inlet pipe and engine cooling water outlet pipe.Connected using clip
It connects and can guarantee effectively sealing against property and damping property.
Further, the metal tube that the exhaust gas connection for breather pipe and cooling water pipe of engine connector for the benefit of conduct heat.
The beneficial effects of the utility model are：Due to the setting of exhaust gas connection for breather pipe and cooling water pipe of engine connector,
And exhaust gas connection for breather pipe described in the bending section semi-surrounding of the U engine cooling water pipe connector, cooling water pipe of engine connect
Head both ends are connected respectively with engine cooling water water inlet pipe and engine cooling water outlet pipe, and when engine works, engine is cold
But the high-temperature water heating exhaust gas connection for breather pipe in water pipe head, and then deliver heat to air filter air outlet pipe so that air filter outlet
Tube temperature degree is largely increased, and effectively eliminates the icing of air filter air outlet pipe internal condensation water, and simple in structure, and arrangement facilitates fast
Victory, it is at low cost.
