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.
