Abstract
The invention relates to an engine cylinder head structure which comprises a cylinder head body. The cylinder head body is provided with an air inlet path, an exhaust air duct, a combustor and a cam shaft chamber, an included angle is formed on the bottom plane of the cam shaft chamber in the air intake direction and the horizontal direction, a main oil return hole is arranged in the lower air intake side of the bottom plane of the cam shaft chamber, and an air vent is formed in the higher exhaust side of the bottom plane of the cam shaft chamber. It can be guaranteed that engine oil of an oil cavity of the cam shaft chamber of a cylinder head smoothly and completely returns to an oil sump, and meanwhile air permeability of the cam shaft chamber can be guaranteed.
Description
Technical field
The invention belongs to engine art, specifically refer to a kind of engine cylinder cover structure.
Background technique
The development trend of car is all a many moneys of Engine Matching vehicle now, but the layout of every sedans is different, and the structure of engine compartment is also different.In order to adapt to these differences, motor often needs to do the variation of some mounted angles.But the oil-returning structure that the variation meeting at these inclination angles covers engine cylinder impacts.This causes the versatility of motor greatly to reduce.
As shown in Figure 1 to Figure 3, present cylinder cap utilizes cylinder bolt via hole (1) as spill port and the vent of camshaft chest oil pocket (2) mostly.The diameter of cylinder bolt via hole is greater than the diameter of cylinder bolt, and cylinder bolt via hole has the effect of oil return and ventilation concurrently.
Because spill port and vent do not distinguish, if if camshaft chest oil pocket has gas blowby in oil return, can cause oil return not smooth.And because the major part of cylinder bolt hole is not the minimum point at camshaft chest oil pocket, also can cause oil return unclean.
Because gasoline engine cylinder cover is often arranged in spark-plug hole (3) cylinder cap by neutral position, cause cylinder cap intermediate portion hollow out, and there is camshaft support base (4) on side, and the wall thickness of camshaft support base is thinner, this causes the intensity of cylinder cap greatly to reduce.
Summary of the invention
The object of the invention is to provide a kind of engine cylinder cover, and this cylinder cap has independently spill port and vent; Spill port is positioned at the minimum point of camshaft chest oil pocket, can effectively solve the smooth and unclean problem of oil return of cylinder cap camshaft chest oil return.
The present invention is achieved by the following technical solutions:
An engine cylinder cover structure, includes cylinder cap body, on described cylinder cap body, is provided with intake duct, air outlet flue, firing chamber and camshaft chest; Described camshaft chest base plane has an angle along airintake direction and substantially horizontal; The air inlet side lower in camshaft chest base plane is provided with main spill port; The exhaust side higher in camshaft chest base plane is provided with vent.
Near described main spill port, be provided with cylinder bolt hole, the opposite side relative with main spill port at cylinder bolt hole is provided with auxiliary spill port.
Described camshaft chest base plane is not more than 40 degree along the angle of airintake direction and substantially horizontal.
In described camshaft chest, be also provided with camshaft support and spark plug fitting seat; The other bolt lug that is provided with of described spark plug fitting seat.
Described spark plug fitting seat connects as one structure by exhaust cam shaft stool and intake cam shaft stool.
The invention has the beneficial effects as follows:
By technological scheme of the present invention, cylinder cap camshaft chest bottom surface has certain inclination angle, in camshaft chest bottom surface, compared with low side, be provided with independently spill port, higher-end is designed with independently vent, can guarantee that motor is when to air inlet side or exhaust side inclination several angle, spill port is positioned at the minimum point of cylinder cap camshaft chest all the time, and vent is positioned at the peak of cylinder cap camshaft chest all the time.The machine oil that can guarantee cylinder cap camshaft chest oil pocket is got back to oil sump smoothly, completely, also can guarantee the vent ability of camshaft chest simultaneously.
Cylinder cap provided by the present invention, the centre of cylinder cap is provided with spark plug erection support, the camshaft erection support of intake and exhaust side can be connected as one, and has effectively increased the intensity of cylinder cap.Spark plug erection support is other simultaneously is also provided with bolt hole, can be used for fixing cylinder cap guard shield, effectively reduces vibration and the noise of cylinder cap guard shield.

Embodiment
Describe by the following examples technological scheme of the present invention in detail, following embodiment is only exemplary, only can be used for explaining and technological scheme of the present invention being described, and can not to be interpreted as is the restriction to technical solution of the present invention.
In technological scheme of the present invention, the form structure of cylinder cap does not improve with prior art, and in this application, do not relate to the cooling water passage in cylinder cap, in the scope that oil passageway does not also relate in the application, that is to say, all technological schemes of the application only relate to the improvement of the technological scheme of camshaft chest environs.
Shown in figure 4 to Fig. 7, a kind of engine cylinder cover, comprises cylinder cap body (10), has intake duct, air outlet flue, firing chamber and camshaft chest (11) on cylinder cap body.As shown in Figure 6, camshaft chest base plane has an angle α along intake and exhaust direction and substantially horizontal, and angle is not more than 40 degree, is preferably 15 degree-25 degree.
The air inlet side that camshaft chest base plane is lower is designed with main spill port (12), at the higher exhaust side of camshaft chest base plane, is designed with vent (13).Near spill port, be provided with cylinder bolt hole (14), the opposite side of cylinder bolt hole is provided with auxiliary spill port (15).
When motor is installed, no matter motor is to air inlet side or the exhaust side maximum α that tilts, and main spill port is the minimum point in camshaft chest all the time, can guarantee that the machine oil of camshaft chest oil pocket can be got back to oil sump smoothly; Vent is positioned at camshaft chest peak all the time, can keep vent unimpeded.And the machine oil of cylinder bolt lug opposite side can be got back to oil sump by auxiliary spill port.
As shown in Fig. 4 and Fig. 7, in the camshaft chest of cylinder cap of the present invention (11), be also provided with camshaft support (16) and spark plug fitting seat (17), the other bolt lug (18) that is provided with of spark plug fitting seat.Spark plug fitting seat is connected as a single entity intake and exhaust cam shaft stool, can effectively increase Intensity of Cylinder Head.The other bolt hole of spark plug fitting seat can also be used to fixedly cylinder cap guard shield etc., can effectively reduce vibration and the noise of cylinder cap guard shield.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiments, scope of the present invention is by claims and be equal to and limit.
