Abstract
The utility model provides an engine hood, which comprises a main body and a baffle plate connected to the main body. The baffle plate is approximately parallel to the main body, and a communicating part communicated with two sides of the baffle plate is disposed on the baffle plate. A breathing channel of a crankcase ventilating system is integrated on the engine hood by the aid of the baffle plate, and accordingly the engine hood solves the problem that an existing breathing channel of a crankcase ventilating system is short so as to increase engine oil consumption in a low-cost manner.
Description
Technical field
The utility model relates to a kind of hood.
Background technique
Motor is typically provided with crankcase, and present engine design tends to miniaturization, compact type development day by day, and the crankcase ventilation system of motor is subject to the layout factor, and it is generally shorter to cause crankcase to be used to introduce the air passageways of ventilation system of fresh air.And the crankcase ventilation system of motor is used for the mixed gas separation of engine crankcase.The short mixed gas separation poor effect that causes engine crankcase easily of the air passageways of the ventilation system of engine crankcase, thus the engine motor oil consumption is increased severely, influence engine performance and life-span.And under the relatively shorter situation of Oil-gas Separation passage, adopting special oil gas separate design to improve the mode of mixed gas separation efficient, cost is generally than higher
The model utility content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of air passageways of integrated ventilation system, can improve the engine cylinder cover of mixed gas separation effect.
A kind of hood, this hood comprise main body and be connected in the baffle plate of main body, and described baffle plate is roughly parallel to described main body, and baffle plate is provided with the connectedness that is communicated with described baffle plate both sides.
Compared to prior art, hood of the present utility model is integrated in hood by baffle plate is set with the respiration channel of crankcase ventilation system, causes the problem that oil consumption increases thereby use cheaply mode to solve crankcase ventilation system respiration channel short-range missile.

Fig. 3 is the schematic perspective view of the main body of hood of the present utility model;
Fig. 4 is the schematic perspective view of the baffle plate of hood of the present utility model;
Fig. 5 is the schematic perspective view under another visual angle of baffle plate of hood of the present utility model.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further specified.
See also Fig. 1 and Fig. 2, the utility model provides a kind of hood 10, comprises main body 20 and is connected in the baffle plate 30 of main body 20.In the present embodiment, main body 20 and baffle plate 30 are for nylon material and adopt the injection moulding mode to make, and baffle plate 30 friction weldings are in main body 20.Be understandable that main body 20 and baffle plate 30 can adopt other materials and use other modes to make, main body 20 and baffle plate 30 can use other suitable modes to interconnect.
Please in the lump referring to Fig. 3 to Fig. 5, hood 10 is provided with main cavity 203.Main body 20 also is provided with respirating tube 205 and is communicated with main cavity 203.Baffle plate 30 is provided with end face 301, offers from the end face 301 of the baffle plate 30 of motor lid 10 to cooperate cavity 303.Baffle plate 30 offers connectedness 305.In the present embodiment, connectedness 305 is roughly tubulose, and it is communicated in baffle plate 30 both sides, and in the present embodiment, connectedness 305 is communicated in the cooperation cavity 303 of baffle plate 30.Its baffle plate 30 is roughly parallel to main body 20.Main body 20 is relative with the end face 301 of baffle plate 30, and the main cavity 203 of main body 20 cooperates the formation respiration channel with the cavity 303 that cooperates of baffle plate 30.The link 305 of baffle plate 30 is opened in the other side of baffle plate 30 with respect to the respirating tube 205 of main body 20.The link 305 of baffle plate 30 is connected with connecting tube (figure does not show).
Motor in use, mixed gas by be connected in baffle plate 30 link 305 connecting tubes enter respiration channel, mixed gas carries out entering the air-strainer bellows after the Oil-gas Separation in respiration channel.Since hood integrated respiration channel, engine structure compactness in the time of not only, also can make machine oil content minimizing by the mixed gas of respirating tube 205, enter the oil level minimizing of burning in the engine cylinder thereby make, not only reduced the oil consumption of motor, also reduce the carbon distribution in the engine cylinder, improved engine performance and service life.
Embodiment's two of the present utility model hood structure and the hood structure among the embodiment one are roughly the same, its difference is, the baffle plate of embodiment's two of the present utility model hood is provided with dividing plate towards hood main body projection perpendicular to the mixed gas direct of travel, and the end face of dividing plate and hood main body has certain interval.Dividing plate increased mixed gas in the traveling process of respiration channel the distance of process, and have the labyrinth effect, and mixed gas clashes into dividing plate, raising Oil-gas Separation efficient in the traveling process of respiration channel, reduce consumption of lubricating oil, improve the ventilation effect of crankcase.
Embodiment's three of the present utility model hood structure and the hood structure among the embodiment one are roughly the same, its difference is, the end face of the baffle plate of embodiment's three of the present utility model hood is provided with a plurality of dividing plates towards hood main body projection, the end face of a plurality of dividing plates and hood main body has certain interval, and vertical mutually between two adjacent dividing plates.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
