Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
A kind of new automobile crankcase ventilation ice protection system as shown in Figure 1 to Figure 3, including crankcase bleed pipe 1, sky
Leaching trachea 3 and expanding adaptor 2, described air filter escape pipe 3 includes main pipeline and base, described base axis and master
Conduit axis is mutually perpendicular to；There is the ventilation duct linkage section connecting crankcase bleed pipe 1 described expanding adaptor 2 one end, logical
The external diameter of airduct linkage section is identical with the internal diameter of crankshaft ventilation tube 1；The other end has the escape pipe linkage section connecting base, escape pipe
Linkage section external diameter is identical with the internal diameter of base；Between described ventilation duct linkage section and escape pipe linkage section by reduced diameter portion even
Connecing, the pipe diameter of reduced diameter portion is by the diameter that the diameter of ventilation duct linkage section is the most excessively escape pipe linkage section.Reducing
Part two ends have fillet excessively to connect.The internal diameter of base is more than the internal diameter of crankcase bleed pipe.Described escape pipe linkage section with
Connected by the first clip 4 between base, between described ventilation duct linkage section and crankcase bleed pipe by the second clip 5 even
Connect.Described air filter escape pipe is AEM material.
Vehicle crankcase ventilation ice protection system of the present utility model, including crankcase bleed pipe, air filter escape pipe and expansion
Open formula adaptor；Expanding adaptor uses variable-diameter structure, it is desirable to crankcase ventilation tube connection ports size according to air pipeline
Bore designs, and uses clamp connection with pipeline；The other end is connected with air filter escape pipe, it is desirable to expand interface bore as far as possible；Should
The gaseous mixture of crankcase bleed pipe is introduced air filter escape pipe by device, because of mixed containing part steam and gasoline engine oil etc. in air-flow
Close gas, increased and air filter escape pipe interface bore by adaptor, can effectively prevent gas moment from freezing；Expanding is transferred
Head reduced diameter portion needs relatively big excessively fillet, prevents inwall burr, upsets air-flow；After air filter escape pipe interface expands bore, can
Ensure that crankcase pressure changes in the range of-4 3Kpa with effective, prevent extreme operating condition negative pressure too low, cause excessive backward flow
Situation；Air filter escape pipe uses AEM material, is connected with expanding adaptor by clip, can guarantee that effectively sealing against property and subtract
Pinking.
New automobile crankcase ventilation ice protection system, mainly includes crankcase bleed pipe 1, air filter escape pipe 3 and expansion
Formula adaptor 2, expanding adaptor 2 is a kind of expansion reducing attachment structure, and adaptor one end connects crankcase bleed pipe 1, separately
One end connects air filter escape pipe 3；Vehicle is under big load even full load mode, and crankcase internal pressure is more than air filter escape pipe
3 pressure, now the mixed gas in crankcase (comprising gasoline, machine oil and steam) is turned by crankcase bleed pipe 1, expanding
Joint 2 anti-channeling is made the return trip empty and is leached trachea 3；Under the conditions of the external world is extremely cold, the gas of air filter escape pipe 3 is closer to atmospheric temperature,
When the clean cold air that the gaseous mixture that anti-channeling is returned is come in air filter escape pipe 3 contacts so that mixed gas is lowered the temperature rapidly, mixing
Steam instantaneous coagulation in gas, causes pipeline to intercept；
This utility model is by increasing expanding adaptor 2 so that gaseous mixture is fully contacted with cold air, on the one hand enlarging
Rear sectional area increases so that in uiform section is long-pending, moisture content concentration reduces, and can be prevented effectively from steam and condense in a large number；On the other hand
When fluid is by variable cross-section, the region flow velocity that sectional area is big slows down, and can alleviate moisture condensation speed；By expanding adaptor
2, effectively the gaseous mixture in crankcase bleed pipe 1 can be transitioned in air filter escape pipe 3 fully, can be prevented effectively from mixed
Conjunction gas freezes, and last mixed gas is burnt in being sent to electromotor in the lump with clean cold air.
Below the preferred embodiment created this utility model is illustrated, but this utility model is created not
Being limited to described embodiment, those of ordinary skill in the art are all right on the premise of this utility model creative spirit
Making modification or the replacement of all equivalents, these equivalent modifications or replacement are all contained in the application claim limited range
In.
