Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but not as to limit of the invention
It is fixed.
Fig. 1 is the use state schematic diagram of the device for metering oil consumption of engine of one embodiment of the present of invention；Fig. 2 is Fig. 1
In piston valve and ball float cooperation schematic diagram.It is pointed out that piston valve simplified partial shows in Fig. 1.Such as Fig. 1 and Fig. 2
It is shown, the device for metering oil consumption of engine of one embodiment of the present of invention, including it is arranged on the stream on the fuel feed pump 61 of engine
Gauge 2 and check valve 5, sequentially pass through flowmeter 2 and check valve 5 enter in engine 6, burning from the interior fuel oil for pumping out of fuel tank 1
Acting.When fuel oil is by flowmeter 2, flowmeter 2 produce pulse signal start to measure oil consumption, flowmeter 2 with it is existing
Technology is identical, will not be repeated here.To solve influence of the oil return to flowmeter 2, the device for metering oil consumption of engine of the present embodiment
Also include the oil storage box 3 for collecting the fuel oil for returning of oil return pipe 62 and the fuel feed pump 61 for sending into engine 6 from engine 6,
The top of oil storage box 3 is provided with the oil inlet 31 being connected with oil return pipe 62, and the bottom of oil storage box 3 is provided with and going out that fuel feed pump 61 is connected
Hydraulic fluid port 32, the junction of oil-out 32 and fuel feed pump 61 is located at the downstream of check valve 5, the effect of check valve 5 be allow oil return not by
Repeat to measure.As depicted in figs. 1 and 2, it is additionally provided with oil storage box 3 and oil-out is highly controlled according to the fuel liquid level in oil storage box 3
32 control units for opening and closing.In this embodiment, the control unit includes piston valve 4 and ball float 7, and piston valve 4 is opened including two ends
Mouthful sleeve 42 and in sleeve 42 and the piston 43 that coordinates with it, the lower end of sleeve 42 is connected with oil-out 32, piston
43 upside is connected by rope 47 with the ball float 7 outside sleeve 42, and multiple is provided with along its circumferential direction on the wall of sleeve 42
Oil leak hole 45.The height that sets of oil leak hole 45 can be adjusted according to the requirement difference to sensitivity, and oil leak hole 45 is closer to set
The lower end of cylinder 42, oil-out 32 is more continually switched on.During specific implementation, at oil-out 32 fix welding fairlead with hair
Connected by three-way pipe between the fuel feed pump 61 of motivation 6.
The course of work of the device for metering oil consumption of engine of the present embodiment is illustrated below in conjunction with Fig. 1 and 2, when engine work
When, the fuel oil in fuel tank 1 enters flowmeter 2 by fuel feed pump 61, and now flowmeter 2 produces pulse signal to start to carry out oil consumption
Measurement.Fuel oil continues through check valve 5 and enters burning in engine 6；Oil return produced by engine 6 is entered by oil return pipe 62
Oil storage box 3, oil return passes through in the dropping process that oil inlet 31 enters in oil storage box 3, and bubbles burst, oil storage box 3 collects oil return
Get up, its liquid level rises, ball float 7 floats, band piston 43 rises.When the oil mass in oil storage box 3 reaches certain value, piston 43
The position of rising is higher than oil leak hole 45 (lower end of piston 43 starts from the draining of oil leak hole 45 higher than the lower end of oil leak hole 45), storage
Fuel oil in oil box 3 is connected by the oil leak hole 45 on the side wall of sleeve 42 with oil-out 32, and fuel oil is again introduced into fuel feed pump 61, is supplied
Answer engine 6.
Due to the effect of check valve 5, the fuel oil out of oil storage box 3 will not flow back to flowmeter 2 and repeatedly be measured.With
Fuel oil flows out, and the fuel level in oil storage box 3 begins to decline, and when certain altitude is dropped to, ball float 7 declines, and piston 43 is being received
Action of Gravity Field and decline, when returning to the position less than oil leak hole 45, piston valve 4 is automatically switched off.
The device for metering oil consumption of engine of the present embodiment, by setting oil storage box 3, can allow oil return to be cooled down and returned
Bubble in oil can be eliminated in oil storage box 3, improve the certainty of measurement of oil consumption.
Preferably, screen pack (not shown) is additionally provided with oil storage box 3, screen pack is located under oil inlet 31
Side.Screen pack can further puncture the bubble in oil return, secondly, can also filter the impurity in oil return.
In order to the gas allowed in oil storage box 3 is excluded in time, as shown in figure 1, in the present embodiment, the upper end of oil storage box 3 is provided with
Spout hole 33, supplied gas discharge, the position of spout hole 33 is higher than oil inlet 31, in order to avoid during normal work, fuel oil is from spout hole 33
Outflow.Additionally, spout hole 33 can also be arranged to be connected with fuel tank 1, fuel oil can be allowed from overflowing when piston valve 4 is blocked
Discharge orifice 33 returns to fuel tank 1, it is ensured that the safety of whole system.
As shown in figure 3, in the present embodiment, the Seal Oil 8 with fuel oil homogeneity is provided with oil storage box 3, Seal Oil 8 floods sleeve
42, the i.e. surface of Seal Oil 8 exceed the upper end of sleeve 42.Due to prestoring a certain amount of normality oil storage, the oil mass in oil storage box 3
Piston valve 4 can be flooded, when piston valve 4 is closed, these Seal Oils 8 also ensure to cover piston valve 4, form an oil
The closed environment of envelope, has both reached the effect of sealing, and sealing cost is reduced again, with simple structure, safe and reliable, manufacture letter
The single, advantage of low production cost, is conducive to marketing.In fact, Seal Oil 8 can also use engine fuel oil in itself,
Do not prestore Seal Oil 8 in oil storage box 3, the purpose of sealing is reached using the oil return of engine 6, simply, in the engine oil
During consumption metering device initialization, some oil return is retained in oil storage box 3, and fuel consumption data is bigger than normal.
In the above-described embodiments, the oil-out 32 is controlled to open according to the fuel level in oil storage box 3 in oil storage box 3
The control unit for closing also takes the structure of other forms, and mode that such as lever and ball float are combined is realized.
Additionally, device for metering oil consumption of engine of the invention goes for being provided with the diesel engine or gasoline of oil return pipe
Machine.The device for metering oil consumption of engine of above-described embodiment is applied to diesel engine, if applied on gasoline engine, in addition it is also necessary to increase right
The part of the gasoline recovery of volatilization.
As shown in figure 4, present invention also offers a kind of automobile fuel consumption management system, including single-chip microcomputer, GPS receiver device and
Any one device for metering oil consumption of engine as described above, single-chip microcomputer receives the geographic position data of GPS receiver device transmission
The fuel consumption data transmitted with the flowmeter of device for metering oil consumption of engine.Geographic position data includes being not limited to its road for being travelled
Condition information, such as city, suburb, highway, common road, single-chip microcomputer is geographic position data and in good time fuel consumption data knot
Close, oil consumption and driving behavior are accustomed to for engine production producer, automobile production producer, human pilot and vehicle management personnel
Analysis.The geographic position data of single-chip microcomputer treatment GPS receiver device and the process of fuel consumption data are same as the prior art, simply originally
The metering of the used device for metering oil consumption of engine of invention is more accurate, and resulting fuel consumption data is more reliable.Additionally, single
Piece machine is also connected with the ECU (electronic control unit) on automobile, obtains the real-time number of the speed, gear and engine speed of automobile
According to being easy to study the relation between oil consumption and these parameters of automobile.
