Specific implementation mode
Below in conjunction with Fig. 1 ~ 2, the content of the utility model is described in detail by specific embodiment.A kind of promotion vacuum pump
Pressure oil channel structures, including engine lubrication system are cooled down by engine cylinder body cylinder cap 2, chain gear chamber cover 3, lubricating oil pump 4, piston
Nozzle, sump strainer 5, oil filter 6, oil cooler 7, cylinder body main oil gallery 12 and oil sump 8 form, wherein：Cylinder cap
It is assemblied in above cylinder body, chain gear chamber cover is assemblied in the side of cylinder body and cylinder cover component, i.e. motor head, becomes displacement oil pump collection
At on chain gear chamber cover, sump strainer assembles cylinder base, forms an entirety after oil sump and cylinder body assembly, this system is also
Including oil groove, oilhole and piston cooling nozzle, the chain nozzle being assemblied on cylinder body top bearing shell, it is arranged one on cylinder body main oil gallery
Cylinder-body oil duct, by oil cylinder head way, connection end oil duct gives vacuum pump pump oil, and the front end of cylinder body main oil gallery is provided with oil duct
Lead to chain nozzle.
Operation principle：When engine works, lubricating oil carries out coarse filtration by sump strainer 5 in oil sump 8 and is drawn onto
It is integrated in the change displacement oil pump 4 on chain gear chamber cover 3, according to the pressure demand of engine main oil gallery, for meeting different works
The requirement of engine lubrication under condition；By lubricating oil pump, lubricating oil is set to obtain a relatively high pressure, for reaching engine
Each position enters by 11 lubricating oil of oil duct on cylinder body in oil filter 6 and oil cooler 7（Such as Fig. 1）, carry out machine
Oil final filtering and cooling, for ensureing cleaning and the operating temperature of lubricating oil；Then lubricating oil enters cylinder body main oil gallery 12,
It is reached between bent axle and cylinder body by the oilhole of the bearing shell 9 on cylinder body 1, oil groove, forms oil film, play as cylinder body and song
The secondary effect that lubrication is provided of axis friction；It increases a cylinder-body oil duct 22 newly on cylinder body main oil gallery, oil duct 21 is increased newly into cylinder cap, into
Enter vacuum pump end oil duct 20 to vacuum pump pump oil, the terminal pressure of vacuum pump and camshaft is ensure that, in cylinder body main oil gallery
Front end is provided with oil duct and leads to chain nozzle, meets the needs of timing chain lubrication；Lubricating oil passes through the oil duct on cylinder body, supply
Piston cooling nozzle lubricating oil, piston cooling nozzle 5 get to lubricating oil on piston, have taken away a part of heat of piston after burning
Amount, reduces the thermic load of piston；The oil duct 21 of cylinder body front end supplies booster oil inlet；Another part lubricating oil is by cylinder body
Upper oil duct, enter in cylinder cap in the oil duct of VVT, pass through the control of VVT solenoid electric valves 10, drive DVVT actuator works
Make, reaching makes intake and exhaust cam valve timing continuous variable, under working conditions of different engines, promotes engine power performance；Machine
Oil enters camshaft internal galleries by the camshaft oil inlet oil duct on cylinder cap 2, then by the oil duct on each cam journal,
So that lubricating oil is reached between camshaft and cam journal, form oil film, play the purpose of lubrication friction pair, reaches vacuum pump oil inlet
Oil duct, while another way enters high-pressure oil pump cooling nozzles；Be above realized by the way of force feed each parts and
Each secondary lubricating requirement of friction.In addition to above-mentioned force feed, the machine oil in oil sump will moisten also by the rotary motion of bent axle
Lubricating oil is splashed to the positions such as connecting rod, piston and realizes lubrication of splashing.After lubricating oil reaches above-mentioned position, by cylinder cap and cylinder body
Drainback passage returns in oil sump.
