Specific implementation mode
Below against attached drawing, by the description of the embodiment, making to the specific implementation mode of the present invention further details of
Explanation.
As shown in Figure 1 to Figure 3, list VVT engine oil galleries are divided to two branches from cylinder body main oil gallery, respectively enter
VVT oil circuits and cylinder cap oil circuit, two parts oil circuit is individually present, using parallel-connection structure.
VVT oil circuits include：Oil duct I 10, VVT control valves oil duct 11, auxiliary oil channel I 12, VVT is connect with cylinder body main oil gallery
One chamber oil duct 13, the first camshaft-bearing cap oil duct 14, VVT oil ducts 15, the second chambers of VVT oil duct 16, the first camshaft-bearing cap
Back oil road 17, VVT control valves back oil road 18.
Wherein, connect with cylinder body main oil gallery oil circuit I 10 use waist type structure, the purpose done so primarily to, make up
Cylinder cap is deformed with cylinder body dislocation when assembly, ensures enough cross-sectional flow areas, and I 10 upper end of oil circuit is connect with cylinder body main oil gallery and uses cylinder
Bonnet bolt seals.Auxiliary oil channel 12 and VVT control valves back oil road 18 are sealed using steel ball 19.
11 the inside of VVT control valves oil duct is equipped with VVT control valves 100, and VVT control valves oil circuit 11 is respectively at the first chambers of VVT
Oil duct 13 is connected with the second chambers of VVT oil duct 16.By VVT control valves 100, VVT control valves oil circuit and the first chambers of VVT can control
The connection or disconnection of oil duct 13 or the connection or disconnection of VVT control valves oil circuit 11 and the second chambers of VVT oil duct 16.To protect
It is oil-filled to demonstrate,prove VVT200, the rotation of camshaft 300 is driven to carry out timing phase adjusting.
In addition, auxiliary oil channel 12 and VVT control valves back oil road 18 is arranged in VVT control valves oil circuit 11.The work of auxiliary oil channel 12
It is penetrated through with being handle and connect oil duct I 10 and VVT control valves oil duct 11 with cylinder body main oil gallery, introduces lubricating oil to VVT control valve oil ducts
In 11.The effect of VVT control valves back oil road 18 is, when VVT carries out phase adjusted, extra machine oil to be discharged.Auxiliary oil channel and
VVT control valve back oil roads use 19 interference seal of steel ball.
The engine is Single Over Head Camshaft and list VVT structures, wherein VVT200 is belt-type structure, while to air inlet
Phase, exhaust phase are adjusted, and simple in structure, cost is relatively low.
VVT200 is mounted on the first camshaft-bearing cap oil duct 14, is formed and is sealed with the first camshaft-bearing cap oil duct 14
Oil pocket.First camshaft-bearing cap oil duct 14 is connected with the first chambers of VVT oil duct 13, the second chambers of VVT oil duct 16 respectively, to protect
VVT 200 is demonstrate,proved when adjusting out of phase angle, is filled with enough machine oil.First camshaft-bearing cap oil duct 14 is additionally provided with two
A first camshaft-bearing cap back oil road 17, extra machine oil can directly let out engine interior.
Cylinder cap oil circuit includes：Oil duct II 20, oblique oil duct I 21, oblique oil duct II 22, third camshaft are connect with cylinder body main oil gallery
Bearing oil duct 23, auxiliary oil channel II 24, intake rocker slinger 25, oblique oil duct III 26, exhaust rocker arm slinger 27, exhaust rocker arm
Oblique oil duct 28, exhaust hydraulic tappet 29, the oblique oil duct 30 of intake rocker, air inlet hydraulic tappet 31.
It is similar with cylinder body main oil gallery connection oil circuit I 10 with cylinder body main oil gallery connection oil duct II 20, waist type structure is also used,
Cylinder cap is deformed with cylinder body dislocation when making up assembly, it is ensured that enough cross-sectional flow areas；Equally, it connect oil duct II with cylinder body main oil gallery
20 upper ends are sealed using cylinder bolt.It is close that intake rocker slinger 25 with 27 both ends of exhaust rocker arm slinger is all made of bowl-type plug 32
Envelope, and lower part is both provided with V-type oil groove 33, for lubricating intake and exhaust rocking arm.
Tiltedly oil duct I 21 connect oil duct II 20 with cylinder body main oil gallery, third camshaft bearing oil duct 23 is connected to, to convex
Wheel shaft 300 is lubricated.In addition, it is provided with branch in oblique oil duct I 21, point a part of machine oil to oblique oil duct II 22, by assisting oil
Road II 24 enters intake rocker slinger, and intake rocker slinger 25 is hollow structure.
Since cylinder cap is provided with oblique oil duct III 26, at this point, the machine oil in intake rocker slinger 25, a part pass through rocking arm
Bolt hole 34 is lubricated camshaft 300；A part is sent to exhaust rocker arm slinger 27, flow direction row by oblique oil duct III 26
The oblique oil duct 28 of gas rocking arm is lubricated exhaust hydraulic tappet 29；In addition, 25 inner engine oil of intake rocker slinger, shakes through air inlet
The oblique oil duct of arm 30 is lubricated air inlet hydraulic tappet 31.
The oblique oil duct of the oblique oil duct 28 of exhaust rocker arm, intake rocker 30 is located in exhaust rocker arm and intake rocker, by adding
The oblique oil duct of work forms.
In addition, being provided with V-type oil groove 32 on intake rocker slinger 25 and exhaust rocker arm slinger 27, air inlet is shaken respectively
Arm is lubricated with exhaust rocker arm.
Single VVT lubricant passage ways of the present invention directly draw two sections of oil circuits in parallel from cylinder body main oil gallery, connect with conventional
Oil circuit ratio, you can the speed for ensureing VVT responses ensures that there is the demand of enough oil pressure in cylinder cap distal end, shows and ring in oil pressure
Answer demand side advantage more obvious.
In single VVT lubricant passage ways, cylinder cap oil circuit flow direction be to circulate from the middle to both ends, traditional cylinder cap oil circuit arrangement be from
One end flows to the other end.Compared with traditional cylinder cap oil circuit, oil circuit of the invention setting, cylinder cap oil pressure is more evenly distributed, cylinder cap
The problems such as oil pressure of distal end is more reliable, and avoidable distal end oil pressure is insufficient and other abnormal sounds.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as use the present invention design and technical solution carry out various unsubstantialities improvement, or it is not improved will
The design and technical solution of the present invention directly applies to other occasions, within protection scope of the present invention.
