Abstract
A cylinder cover comprises a top cover and a side wall, an exhaust channel is longitudinally arranged on the side wall, an inlet of the exhaust channel is arranged at the lower end of the exhaust channel, and an outlet of the exhaust channel is arranged on the top cover. The technical problems that a cylinder cover in the prior art requires additional parts such as breathers and the like to result in complicated engine structure and complexity in processing and mounting are resolved. The cylinder cover is simple in structure, the parts such as the breathers and the like are omitted, the structure of an engine is more compact, cost is reduced, and the cylinder cover is especially suitable for diesels with small and medium powers.
Description
Technical field
The utility model relates to a kind of cylinder head cover, specifically a kind of cylinder head cover that increases air-out apparatus.
Background technique
Cylinder is the empty chamber of in-engine cylindrical shape, and there is a piston that is promoted by the pressure or the expansive force of working fluid the inside.Cylinder head be installed in cylinder block above, from the top seal cylinder and constitute the firing chamber.Cylinder head cover is used for hiding and the sealing cylinder head, and lubricant oil is remained on inside, makes lubricant oil to be hedged off from the outer world, simultaneously with contaminants such as dirt and moisture in outside.For save cost, just waste gas that diesel engine produced when moving and machine oil mist of oil need can enter atmosphere through after the resuscitation apparatus condensation.Common medium and small power diesel engine cylinder head cover has only seal action, and the discarded and machine oil mist of oil that diesel engine when operation produces enters atmosphere after by the resuscitation apparatus condensation.
A kind of cylinder head cover integral engine crankcase bleeder is disclosed among the Chinese patent literature CN101984225A, comprise cylinder head cover, the oil gas condensation cavity, baffle plate, the bolt pillar, totally-enclosed partition panel, respirating tube, the resuscitation apparatus air outlet channel, resuscitation apparatus give vent to anger sebific duct and stay bolt, the rear end of cylinder head cover is provided with the oil gas condensation cavity, condensation cavity is a single layer structure, be provided with the bolt pillar between oil gas condensation cavity and the baffle plate, totally-enclosed partition panel and semiclosed partition panel are vertical setting for separately breakpoint with the bolt pillar, baffle plate is as the base plate of bolt pillar and totally-enclosed partition panel, respirating tube is contained on the baffle plate oil gas inlet as crankcase, totally-enclosed partition panel is isolated respirating tube and resuscitation apparatus air outlet channel, the lower end of semiclosed partition panel and side leave the space respectively and between baffle plate and the condensation cavity inwall, and resuscitation apparatus air outlet channel top is connected to the resuscitation apparatus sebific duct of giving vent to anger.In this technological scheme, mist of oil in the engine crankcase is under the differential pressure action in the crankcase and the external world, rise to the top of motor, suck mist of oil by respirating tube and enter condensation cavity, on the bolt pillar is in the chamber, do clockwise flowing, and after the cavity wall condenses, flow on the baffle plate, flow back to by the return opening that is located at the baffle plate first area in the rocker arm chamber of engine cylinder cover, reach the purpose of Oil-gas Separation.But the complex structure of cylinder head cover in this technological scheme, so the complex manufacturing of cylinder head cover, this exterior siding and totally-enclosed partition panel must guarantee sealing, have further improved its difficulty of processing, increase cost.
The model utility content
For this reason, technical problem to be solved in the utility model is cylinder head cover complex structure of the prior art, requirement on machining accuracy is higher, processing technology is complicated, thereby proposes a kind of simple in structure, cylinder head cover of being easy to process.
For solving the problems of the technologies described above, a kind of cylinder head cover of the present utility model comprises top cover and sidewall, is vertically arranged with the exhaust passage on the described sidewall, and the inlet of described exhaust passage is arranged at the lower end, and the outlet of described exhaust passage is arranged on the top cover.
The internal diameter of described exhaust passage is that 5.5mm is to 7mm.
The internal diameter of described exhaust passage is 6mm.
The external diameter of described exhaust passage is 12mm-17mm.
The external diameter of described exhaust passage is 15mm.
Described exhaust passage top cover is provided with one and extends passage.
Technique scheme of the present utility model has the following advantages compared to existing technology,
(1) cylinder head cover described in the utility model, comprise top cover and sidewall, be vertically arranged with the exhaust passage on the described sidewall, the inlet of described exhaust passage is arranged at the lower end, the outlet of described exhaust passage is arranged on the top cover, when the gas in the cylinder head cover is discharged, further cool off through the exhaust passage, come back in the diesel engine after the condensation of part machine oil mist of oil, remaining waste gas enters atmosphere or enters in other suction tude and handles, and this is simple in structure, when realizing exhaust, reach the effect of condensation, saved correlated parts such as resuscitation apparatus, make that the structure of motor is tightr, reduced cost.
(2) cylinder head cover described in the utility model, the internal diameter of described exhaust passage be 5.5mm to 7mm, preferred 6mm, the needs of this size conforms exhaust and mist of oil condensation, and be arranged on the effect that has exhaust preferably and mist of oil condensing reflux in the housing.
(3) cylinder head cover described in the utility model, the external diameter of described exhaust passage are 12mm-17mm, and preferred 15mm has guaranteed it to be arranged on the size of exhaust passage in the cylinder head cover can not to occupy too big space.
(4) cylinder head cover described in the utility model, described exhaust passage top cover is provided with one and extends passage, form bending structure, so just prolonged exhaust channel length, make cooling effect better, be more conducive to the condensing reflux of mist of oil, and exhaust is unaffected, energy saving more, practicability is good.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment of the utility model also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the sectional view of cylinder head cover described in the utility model;
Fig. 2 is another embodiment's of a cylinder head cover described in the utility model sectional view;
