The power supply of motivation controller.Preferably, above-mentioned power supply unit is using the battery on the vehicle of the lubricating system.
The pressure sensor for being connected to engine controller is provided in above-mentioned main oil gallery, for measuring the reality in main oil gallery
Border pressure, engine controller determine when to need to open according to the comparison result of actual pressure and preset pressure in main oil gallery
Dynamic auxiliary oil pump come assist main oil pump carry out fuel feeding.
It is realized by above-mentioned setting and main oil pump and auxiliary oil pump is parallel between sump strainer and oil filter, it is main
It is used to be lubricated friction pair each in booster and engine etc..Measuring signal is fed back to engine by pressure sensor
Controller, engine controller obtain corresponding main oil gallery pressure, and judge the size relation of main oil gallery pressure and preset pressure,
If main oil gallery pressure is more than or equal to preset pressure, then illustrate to have been able to meet main oil gallery separately through main oil pump fuel feeding at this time
The pressure demand of inner engine oil, when individually carrying out fuel feeding to main oil gallery only with main oil pump at this time, specifically, main oil pump provides power
The machine oil in oil sump is pumped, the machine oil of oil sump is made to pass sequentially through sump strainer filtering, first check-valve, main oil pump, machine
Main oil gallery is supplied after oil rectifier filtering, oil cooler are cooling, booster is then passed through and each friction is secondary, and to increasing
After depressor and each friction pair are lubricated, it is back to oil sump.
If the pressure in main oil gallery is less than preset pressure, illustrate only not can guarantee main oil by main oil pump fuel feeding at this time
Machine oil in road has enough pressure, and engine controller will send command signal to pilot controller, and pilot controller will
Auxiliary oil pump work is controlled, realizes that by main oil pump and auxiliary oil pump be simultaneously main oil gallery fuel feeding, to meet the lubrication of engine
It is required that.Specifically, providing power pumps oil sump simultaneously for pilot controller control auxiliary oil pump work, main oil pump and auxiliary oil pump
Interior machine oil after filtering the machine oil of oil sump by sump strainer, is divided into two oil circuits, and an oil circuit passes through first check-valve
After flow to main oil pump, another oil circuit flows to auxiliary oil pump after second check-valve, and then two oil circuits collect in oil filter,
Main oil gallery is supplied after oil filter filtering, oil cooler are cooling, it is then secondary to booster and each friction again to carry out
Lubrication, and oil sump is back to after being lubricated to booster and each friction pair.
The present embodiment additionally provides a kind of control method of above-mentioned engine lubrication system, and Fig. 2 is the present embodiment engine
The flow chart of the control method of lubricating system is described in detail the control method referring to Fig. 2.
In S1, engine working process, judge whether the actual pressure in main oil gallery is less than preset pressure, if so, holding
Row S2, if it is not, then executing S3.
Above-mentioned preset pressure is determined according to engine speed and engine load rate, and engine speed and engine are negative
The different corresponding preset pressures of lotus rate are also different, and engine load rate is equal to actual fuel injection amount and throttle under current rotating speed
The ratio of distributive value when standard-sized sheet, distributive value are determined that the actual fuel injection amount under current rotating speed is hair by the current opening size of throttle
Motivation controller is calculated according to rail pressure and power-up time, and specific calculation is the prior art, no longer superfluous in detail herein
It chats；Distributive value is definite value when throttle wide under a certain revolving speed, and the engine of certain different model, distributive value is big when throttle wide
Small difference.For the engine of every kind of model, above-mentioned preset pressure is to pass through with engine speed, the relationship of engine load rate
The determining data form of test is repeated several times.
Engine speed is measured by speed probe, and speed probe is electrically connected to engine controller, is realized to hair
The real-time monitoring of motivation revolving speed.According to current engine load rate and engine speed pass through the relationship tabled look-up determine it is corresponding
Preset pressure.
S2, starting auxiliary oil pump, and the pressure in main oil gallery be more than or equal to preset pressure when, auxiliary oil pump stop supply
Oil.
The discharge capacity of selected mechanical oil pump is small when the discharge capacity of main oil pump is not than using auxiliary oil pump in the present embodiment, and due to
The discharge capacity of mechanical oil pump used by the engine of different model is different, no longer specific herein to limit, and can be avoided engine and exists
When normal revolution sub-load, mechanical oil pump is mentioned when there is main oil gallery inner engine oil flow, the situation of pressure surplus and high revolving speed
For more lubricating oil, and main oil gallery is made the case where lubricating oil pressure release is back to oil sump occur because pressure is excessive, solved
The problem of mechanical oil pump power wastage.Due to having selected the main oil pump of smaller displacement, production cost is saved, main oil pump is reduced
Volume, solve the problems, such as in the prior art main oil pump volume it is excessive and caused by difficulty in arrangement.
When actual pressure in main oil gallery is less than preset pressure, illustrate that oil pressure is insufficient at this time, simple relies on main oil pump
Fuel feeding is no longer satisfied lubrication needs, needs to start auxiliary oil pump at this time, is simultaneously main oil gallery by auxiliary oil pump and main oil pump
Fuel feeding.
Since auxiliary oil pump is variable pump, it can be calculated by pilot controller using PID and adjust auxiliary oil pump
Discharge capacity adjusts the discharge capacity of auxiliary oil pump, in main oil gallery in real time according to the difference of actual pressure and preset pressure in main oil gallery
When difference between interior pressure and preset pressure is larger, it can suitably increase the discharge capacity of auxiliary oil pump, the pressure in main oil gallery
When difference between power and preset pressure is smaller, auxiliary oil pump is worked using small displacement, so that the pressure in main oil gallery can be fast
Speed reaches preset pressure, without regard to being more than pressure in main oil gallery, while avoiding the frequent start-stop of auxiliary oil pump.Using
Electronic variable pump can be realized lubricating system and lubricate on demand, save oil consumption.The present embodiment also passes through filter Hysteresis control, avoids
Auxiliary lubricating oil pump frequent start-stop, as to how avoiding auxiliary lubricating oil pump frequent start-stop by filter Hysteresis control is existing skill
Art is not described in detail herein.
S3, continue by main oil pump to be main oil gallery fuel feeding.
When actual pressure in main oil gallery is more than or equal to preset pressure, illustrate only by main oil pump fuel feeding at this time
Enough meet lubrication needs.
Using above-mentioned engine lubrication system, common duty requirements individually can be met using main oil pump, if in idling
Or under the operating conditions such as anxious acceleration, the machine oil in main oil gallery only not can guarantee with enough pressure by main oil pump fuel feeding, at this time may be used
To be jointly main oil gallery fuel feeding by auxiliary oil pump and main oil pump, to meet the lubricating requirement under engine special operation condition.
Obviously, the above embodiment of the present invention is just for the sake of clearly illustrating examples made by the present invention, and being not is pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
Made any modifications, equivalent replacements, and improvements etc., should be included in the claims in the present invention within the spirit and principle of invention
Protection scope within.
