Description
Technical field
This utility model relates to technical field of automobile engine, in particular to the air inlet of a kind of PCV system
Structure.
Background technology
PCV system, refers to that the mixed gas in crankcase is forcibly introduced into gas handling system to be participated in again firing
The system burnt.This system can prevent machine oil from going bad, prevent crankcase inner oil seal from revealing and preventing various oil vapour atmosphere pollution.One
As mixed gas in situation crankcase be to introduce gas handling system by external crankcase bleed pipe, but external airduct system
Bulk cargo joins complexity, and mixed gas can lose heat in transmitting procedure, and when causing entry into gas handling system, temperature is relatively low, is unfavorable for
The second-time burning of gas.
Utility model content
The purpose of this utility model seeks to solve the deficiency of above-mentioned background technology, it is provided that a kind of positive crankcase ventilation system
The air intake structure of system, this structure instead of air-line system by offering air channel in cylinder head and inlet manifold, it is not necessary to assembling, and
Improve mixed gas thermal conversion efficiency in transmitting procedure.
For realizing this purpose, the air intake structure of the PCV system designed by this utility model, including cylinder
Lid and inlet manifold, it is characterised in that: the inside of described cylinder head has the inlet channel connected with crankcase, described cylinder head
Flange face on have the air vent connected with inlet channel, the cylinder cap flange face of described inlet manifold has and air vent pair
The outlet passageway that should connect with the cylinder cap air inlet of inlet manifold.
Concrete, described inlet channel includes that top connects with crankcase, bottom extends to first within cylinder head and leads to
The second channel that road connects with the bottom of first passage with one end, the other end is closed；Connect between described second channel and air vent
It is connected to third channel.
Further, the axial direction of described second channel and the axial direction of cylinder head are identical.
Further, described air vent is opened between adjacent two flange face air inlets of cylinder head, described threeway
The axial direction in road is vertical with the axial direction of second channel.
Concrete, described outlet passageway includes that one end is closed, the other end connect with the cylinder cap air inlet of inlet manifold the
The clematis stem road that Five-channel and two ends connect respectively at two adjacent cylinder cap air inlets of inlet manifold.
The beneficial effects of the utility model are: instead of crankcase bleed pipe by intake and exhaust channel, crankcase ventilation adds
The parts such as thermal, reduce cost.Simultaneously as mixed gas is delivered to inlet manifold through cylinder head, mixed gas exists
Charge before burning preheating, improve efficiency of combustion, reduce oil consumption.Gas handling system designed by this utility model can be used for
The Development of Modular of PCV system, practical.

Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
The air intake structure of the PCV system as shown in Fig. 17, including cylinder head 1 and inlet manifold 2, gas
The inside of cylinder cap 1 has the inlet channel connected with crankcase, and the flange face of cylinder head 1 has the row connected with inlet channel
QI KOU 3, the cylinder cap flange face of inlet manifold 2 has what cylinder cap air inlet 4 with inlet manifold 2 corresponding with air vent 3 connected
Outlet passageway.
As shown in Fig. 25, inlet channel includes that top connects with crankcase, bottom extends to first within cylinder head 1
The second channel 6 that passage 5 connects with the bottom of one end with first passage 5, the other end is closed；Between second channel 6 and air vent 3
Connect and have third channel 7.
As it is shown on figure 3, the axial direction of second channel 6 is identical with the axial direction of cylinder head 1.
As it is shown in figure 1, air vent 3 is opened between adjacent two flange face air inlets 10 of cylinder head 1, as it is shown in figure 5,
The axial direction of third channel 7 is vertical with the axial direction of second channel 6.
As it is shown in fig. 7, outlet passageway includes that one end is closed, the other end connect with the cylinder cap air inlet 4 of inlet manifold 2
The clematis stem road 9 that Five-channel 8 and two ends connect respectively at two adjacent cylinder cap air inlets 4 of inlet manifold 2.
Work process of the present utility model is: first devises two on the cylinder cap flange face of inlet manifold 2 and gives vent to anger logical
Road (Five-channel 8 and clematis stem road 9), the cylinder cap air inlet face in cylinder head reserves two breach (air vent 3), when cylinder head 1
When assembling with inlet manifold 2, two outlet passageways connect the air vent 3 that cylinder cap air inlet face is reserved respectively, and air vent 3 passes through cylinder cap
The passage of cast inside is connected to crankcase.
When electromotor runs, the mixed gas in crankcase is under the effect of air-intake negative-pressure, through first passage 5, second
Passage 6, third channel 7, air vent 3 and outlet passageway (Five-channel 8 and clematis stem road 9) are incorporated into by cylinder cap air inlet 4
Combustor burns.
The degree of depth of inlet manifold 2 passage and diameter are through design, it is ensured that suck the crankcase gaseous mixture scale of construction equilibrium of each cylinder.
The above, be only preferred embodiment of the present utility model, not do any to structure of the present utility model
Pro forma restriction.Every according to technical spirit of the present utility model, above example is made any simple modification, equivalent
Change and modification, all still fall within the range of the technical solution of the utility model.
