Description

A kind of cylinder head oil channel structures
Technical field
The utility model belongs to technical field of automobile engine, more particularly, to a kind of cylinder head oil channel structures.
Background technique
Modern motor spirit machine is to realize improving performance, reduce discharge etc., generally uses VVT gear, liquid Press tappet and roller rocker arms mechanism.VVT gear, hydraulic tappet and roller rocker arms mechanism need to arrange corresponding control System and lubricant passage way, camshaft are also required to arrangement lubricant passage way, these oil circuits are generally arranged into cylinder head, make air cylinder head structure It is extremely complex, increase the development cost of cylinder head.After engine stop, the lubricating oil in cylinder head oil circuit flows back into oily bottom Shell, when engine is again started up, oil circuit can not establish rapidly the oil pressure met the requirements in cylinder head, lead to variable valve timing Mechanism, hydraulic tappet and roller rocker arms mechanism can not work normally, and lead to reduced performance, and discharge increases.
Utility model content
The utility model for overcome the deficiencies in the prior art, provides the cylinder head that a kind of gasoline engine performance is good, discharge is few Oil channel structures.
To achieve the goals above, the utility model uses following technical scheme:A kind of cylinder head oil channel structures, including gas Cylinder cap working connection, VVT gear oil circuit, hydraulic tappet oil circuit and Oil line for camshaft;The cylinder head working connection includes The longitudinal main oil gallery being connected with cylinder block working connection and the lateral main oil gallery being connected with longitudinal main oil gallery, the main oil in the longitudinal direction Check valve is equipped in road.The utility model in longitudinal main oil gallery by being arranged check valve, after engine stop, prevents gas Lubricating oil in cylinder cap oil circuit flows back into oil sump, and when engine is again started up, oil circuit can rapidly establish oil in cylinder head Pressure enables VVT gear, hydraulic tappet and roller rocker arms mechanism rapidly to enter working condition, and then is promoted The working performance of gasoline engine reduces discharge amount.
Further, air inlet side oil circuit and out gas side oil circuit, the air inlet side oil circuit are communicated on the lateral main oil gallery Including air inlet side longitudinal direction oil circuit and the air inlet side transverse direction oil circuit being connected with air inlet side longitudinal direction oil circuit, the gas side oil circuit out includes Gas side longitudinal oil road and the gas side transverse direction oil circuit out being connected with gas side longitudinal oil road out out;By being arranged on lateral main oil gallery Air inlet side oil circuit and out gas side oil circuit, and air inlet side oil circuit includes the air inlet side longitudinal direction oil circuit being mutually communicated and air inlet side laterally oil Road, gas side oil circuit includes the gas side longitudinal oil road and out gas side transverse direction oil circuit out being mutually communicated out, is realizing inlet and outlet two sides While oil communication, reduce the length of oil circuit, convenient for the arrangement of oil circuit.
Further, the hydraulic tappet oil circuit includes the air inlet side hydraulic tappet oil being connected with air inlet side transverse direction oil circuit Road and the gas side hydraulic tappet oil circuit out being connected with gas side transverse direction oil circuit out.
Further, the Oil line for camshaft include the intake-side camshaft oil circuit being connected with air inlet side transverse direction oil circuit and What is be connected with gas side transverse direction oil circuit out goes out gas side Oil line for camshaft.
In conclusion the utility model by the way that check valve is arranged in longitudinal main oil gallery, after engine stop, prevents Lubricating oil in cylinder head oil circuit flows back into oil sump, and when engine is again started up, oil circuit can establish rapidly oil in cylinder head Pressure, VVT gear, hydraulic tappet and roller rocker arms mechanism rapidly and then working condition, and then can promote gasoline engine Working performance, reduce discharge amount.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the main oil gallery cross-sectional view of the utility model.
Specific embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction with the utility model reality The attached drawing in example is applied, the technical solutions in the embodiments of the present invention are clearly and completely described.
As shown in Figs. 1-2, a kind of cylinder head oil channel structures, including cylinder head working connection, VVT gear oil circuit, Hydraulic tappet oil circuit and Oil line for camshaft;Specifically, VVT gear oil circuit includes VVT gear control Oil circuit and lubricant passage way, above-mentioned oil circuit are the prior art, are repeated no more;Hydraulic tappet oil circuit includes hydraulic tappet control oil circuit It is the prior art with lubricant passage way and roller rocker arms control oil circuit and lubricant passage way, above-mentioned oil circuit, repeats no more;The gas Cylinder cap working connection includes that the longitudinal main oil gallery 1 being connected with cylinder block working connection and the transverse direction being connected with longitudinal main oil gallery 1 are main Oil duct 2, the longitudinal direction main oil gallery 1 is interior to be equipped with check valve 11, after can preventing gasoline engine from stopping operating by the check valve 11 of setting Lubricating oil is back to oil sump, and then when engine is again started up, oil circuit can rapidly establish oil pressure in cylinder head, so that can Air valve variation timing mechanism, hydraulic tappet and roller rocker arms mechanism can rapidly enter working condition, promote the work of gasoline engine Performance reduces discharge amount, specifically, the working principle of the check valve is the prior art, this will not be repeated here.
Further, air inlet side oil circuit and out gas side oil circuit, the air inlet side oil circuit are communicated on the lateral main oil gallery 2 Including air inlet side longitudinal direction oil circuit 31 and the air inlet side transverse direction oil circuit 32 being connected with air inlet side longitudinal direction oil circuit 31, the gas side oil out Road include out gas side longitudinal oil road 41 and be connected with gas side longitudinal oil road 41 out go out gas side transverse direction oil circuit 42, the air inlet side Oil circuit and out gas side oil circuit be separately positioned on cylinder head inlet and outlet two sides and respectively with inlet and outlet side VVT gear Oil circuit is connected.
The hydraulic tappet oil circuit include the air inlet side hydraulic tappet oil circuit 5 being connected with air inlet side transverse direction oil circuit 32 and with What gas side transverse direction oil circuit 42 was connected out goes out gas side hydraulic tappet oil circuit 6.
