Described bipass is provided with electrically-controlled valve, and electrically-controlled valve is opened rear machine oil and is back under gravity in oil sump.
Described sump volume is about 2 ~ 2.5L, can store 2/5 ~ 3/5 of total oil level.
Described return tube leads to the side that the import of oil sump is arranged on oil sump, and entrance is from the bottom surface 15cm of oil sump.
Described lubrication system is controlled the unlatching of electrically-controlled valve with closed by car body controller.
Described oil sump 3 is fixed by screw and engine body.
A kind of engine lubrication system, owing to adopting above-mentioned structure, engine lubricating oil heating rate when the utility model can improve warming-up, reduce simultaneously at a high speed large load time oil temperature.Between friction surface, form elasticity oil film, form hydrodynamic lubrication, reduce surface friction drag and power consumpiton, to improve reliability and the durability of engine operation.Invention is not changing under former machine lubrication system oil circuit prerequisite, and by a set of oil circuit of the external extra increase of engine, structure is simple, is easy to realize.

Embodiment
The utility model comprises in cylinder body and is provided with two back oil roads 1 and machine oil is guided to external engine and is injected into oil sump 3 by oil duct 2; Connect return tube 6 by bipass bottom oil sump 3, then machine oil is injected in oil sump 7; The surrounding of oil sump 3 is provided with radiating fin 4 simultaneously.Bipass is provided with electrically-controlled valve 5, and electrically-controlled valve 5 is opened rear machine oil and is back under gravity in oil sump 7.The import that return tube 6 leads to oil sump 7 is arranged on the side of oil sump 7, and entrance is from the bottom surface 15cm of oil sump 7.
As shown in Figure 1, the utility model provides a kind of fast lifting NEDC circulation warm-up period lubricating oil temperature, reduces lubricating oil viscosity, reduces warm-up period engine component frictional force; Meanwhile, when engine speed and load increase, when oil temperature reaches 85 ~ 90 DEG C, electrically-controlled valve 5 is opened, and there is radiating fin 4 on oil sump 3 surface, and part machine oil cools through oil sump 3, large duty oil temperature at a high speed can be improved too high, improve engine mechanical efficiency, improve fuel consumption rate.In addition because warm-up period lubricating oil viscosity reduces, between component friction pair, lubrication is improved, and reduces the friction pair dry friction time, is conducive to reducing between component friction pair wearing and tearing, and improves stability and the reliability of motor.
Engine lubrication system oil circuit in the utility model is divided into two-way: traditional lubrication system oil-way comprises oil sump, oil pump, filter cleaner, cylinder body main oil gallery, cylinder body main oil gallery connection main bearing oil duct, cooling jet oil duct and gear chamber oil duct etc.; The a set of oil circuit of present increase, the oil-way system comprising increase comprises connecting in cylinder body and controls the return tube 6 of bipass way outlet to oil sump 7 to the back oil road of two outside machine 1, the oil sump 3 that can store machine oil total amount 2/5 ~ 3/5, bipass and electrically-controlled valve 5, electrically-controlled valve 5.When oil temperature reaches designated value, electrically-controlled valve controls the valve open of electrically-controlled valve 5, and in oil sump 3, machine oil under gravity, and machine oil gets back to oil sump 7 by return tube 6.The oil level that participation when reducing warming-up circulates, thus allow machine oil be rapidly heated; When oil temperature reaches 85 DEG C, electrically-controlled valve 5 is opened, the oil return of gravity part, because the subzero engine oil of oil sump 3 mixes with the high temperature of oil sump 7, oil temperature declines, and electrically-controlled valve is closed, again when oil temperature reaches 85 DEG C, again open, repeatedly carry out, when can make warming-up like this, oil temperature raises, engine oil viscosity reduces, reduce the secondary surface friction drag of engine movements, reduce mechanical loss, improve fuel consumption rate.
When engine speed and load increase, when oil temperature is more than 85 DEG C, electrically-controlled valve 5 is opened, part machine oil through this oil circuit of oil sump 3, due to oil sump 3 having radiating fin 4, can cooling machine oil, can improve large duty oil temperature at a high speed too high, viscosity reduces large, causes oil film difficulty or ease between friction pair to set up problem, then improve engine mechanical efficiency, improve fuel consumption rate.
Engine tilts angle is comparatively large upon start up, and now car body controller sends the unlatching of instruction electrically-controlled valve, and oil sump 3 does not store machine oil, ensures that motor normally lubricates.If after startup warming-up, engine tilts is less or when not tilting, electrically-controlled valve is closed, and carries out rapid heating machine oil strategy.
Machine internal oil channel 2 and oil sump 3 entrance, oil sump 3 exports and bipass entrance, and bipass outlet all adopts Flange joint with oil sump 7 entrance, and connected element ensures the sealing of machine oil by sealing gasket and seal ring.Oil sump 3 can be fixed by screw and body, and its body must have corresponding mounting hole; Oil sump 3 or according to car load space arrange engine cavity relevant position.Arranged according to motor and car load space by external lubricant pipe, but pipeline camber will be avoided excessive, must ensure that oil circuit is unimpeded, realizes machine oil and supplies normally and circulate.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the various improvement that technical solutions of the utility model are carried out; or directly apply to other occasion, all within protection domain of the present utility model without improving.
