Abstract
The invention provides an engine VVT phaser oil supply passage structure. An oil trough ring is arranged on the internal wall of a shaft hole of a camshaft of a cylinder cover and a corresponding internal wall of a camshaft cover; the oil trough is communicated with an oil hole of an oil inlet passage or an oil return passage to which the camshaft leads an internal oil chamber and an external oil chamber of the VVT phaser; the oil trough of the cylinder cover is provided with an oil hole communicated with an engine oil control valve; meanwhile, the external wall of the shaft neck of the camshaft is also provided with an oil trough ring; the oil trough is communicated with the oil hole of the oil inlet passage or the oil return passage to which the camshaft leads the internal oil chamber and the external oil chamber of the VVT phaser, and is also communicated with the oil hole leading to the engine oil control valve and arranged at a corresponding position of the cylinder cover. As only one oil trough is arranged on the cylinder cover, the structure reserves sufficient space for the design and installation of the shaft cover of the camshaft; the other oil trough is arranged on the shaft diameter of the camshaft, which is beneficial for reducing the diameter of the shaft, improving the strength of the position of the camshaft and reducing the processing difficulty.
Description
Technical field
The present invention relates to engine fuel system, particularly the VVT phase discriminator oil supply system of small displacement engine is arranged
Background technique
When motor moves, VVT (Variable Valve Timing, Variable Valve Timing) system is by OCV (OCV Oil Control Valve, Oil control valve) adjusting enters the purpose that the interior required oil level of outer oil cavity of cam phaser reaches change camshaft timing phase place, this just requires oil supply system to comprise the interior outer oil cavity of an oil input channel and a next corresponding VVT of back oil road, and these two oil ducts can exchange, and promptly oil input channel can be changed into back oil road, and back oil road can be changed into oil input channel.
Generally, VVT phase discriminator oil supply system generally is to arrange two oil grooves on the cylinder cap or arranging that on camshaft two oil grooves satisfy the requirement that two oil ducts are got oil respectively.But this dual mode all has certain defective: if arrange two oil grooves on cylinder cap, can limit the arrangement space of camshaft cover bolt hole, design, the machine that will certainly have influence on camshaft cover adds, intensity and installation; And on camshaft, arrange and can increase two oil grooves the diameter of camshaft bearing journal equally, and can have influence on the intensity and the difficulty of processing of camshaft.
Summary of the invention
The objective of the invention is to arrange that at the VVT of present motor there is significant limitation in the space of oil supply gallery on cylinder head, a kind of new engines VVT phase machine oil supply duct structure is proposed, the diameter of axle of camshaft is reduced, be convenient to the design and installation of camshaft cover simultaneously.
Technological scheme of the present invention is as follows:
A kind of engines VVT phase machine oil supply duct structure comprises the oil inlet passage and the drainback passage that are axially disposed within the camshaft outer oil cavity in the OCV Oil Control Valve that is communicated with main oil supply system and the VVT phase discriminator; It is characterized in that, the camshaft shaft hole inwall of cylinder head and corresponding camshaft cover inwall are provided with a circle oil groove, this oil groove is communicated with the oilhole that camshaft leads to the oil inlet passage of VVT phase discriminator outer oil cavity, and the oilhole that is communicated with OCV Oil Control Valve is arranged in the oil groove of cylinder head; Also arrange a circle oil groove at the axle journal outer wall of camshaft, the oilhole that leads to the drainback passage of oil pocket in the VVT phase discriminator of this oil groove and camshaft is communicated with, and is communicated with the oilhole towards OCV Oil Control Valve of corresponding position setting on the cylinder head.
This structure has been reserved sufficient space owing to only arrange an oil groove on cylinder head for the design and installation of camshaft cover, and another oil groove is arranged in the cam shaft diameter place, helps reducing the diameter of axle, improves the intensity at this position of camshaft, and reduces difficulty of processing.

Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, this VVT phase discriminator oil supply gallery structure relates to the camshaft 4 of motor, cylinder head 2, camshaft cover 1 and VVT phase discriminator 3, in conjunction with referring to Fig. 2, Fig. 2 A and Fig. 2 B, in camshaft 4, axially be provided with the oil inlet passage 41 and the drainback passage 42 of the interior outer oil cavity that is communicated with VVT phase discriminator 3, machine adds a circle oil groove 43 on the axle journal outer wall of camshaft 4, this oil groove 43 is communicated with the oil inlet passage that leads to outer oil cavity in the VVT phase discriminator of camshaft or the oilhole 44 of drainback passage, and simultaneously corresponding with the oil inlet hole 22 that leads to the OCV valve that is provided with of corresponding position on the cylinder head 2, see Fig. 3.Simultaneously, referring to Fig. 3 and Fig. 4, on the inwall of the camshaft shaft hole inwall of cylinder head 2 and corresponding camshaft cover 1, oil groove 21 and 11 are set respectively, two oil grooves 21 and 11 surround and form a circle, this oil groove leads to the oil inlet passage of the interior outer oil cavity of VVT phase discriminator with camshaft or the oilhole 45 of drainback passage is communicated with, and the spill port 23 that is communicated with OCV Oil Control Valve is arranged in the oil groove 21 of cylinder head.Like this, machine oil is through the OCV valve, enter oil groove 43 on the camshaft 4 by oil inlet hole 22 on the cylinder head 2, flow to the outer oil cavity of VVT phase discriminator 3 by the oil inlet passage 41 of the oilhole in the oil groove 43 44 in camshaft, machine oil enters interior oil pocket by the outer oil cavity of VVT phase discriminator 3, then by drainback passage 42 in oilhole 45 flows to oil groove 11 and the oil groove 21 on the cylinder head 2 on the camshaft cover 1, after the spill port 23 on the cylinder head 2 flows back to main oil supply system through the OCV valve.As seen, this structural design is convenient to the design and installation of camshaft cover simultaneously fully guaranteeing that oil circuit smoothly under the prerequisite, reduces the diameter of axle of camshaft.
