Machine internal structure complicated state.And new engine oil level being measured based on magnetostrictive liquid level sensor, needs will pass
Sensor is vertically mounted in engine sump tank by oil discharge screw, and most of electromotor oil discharge screw is in oil sump side at present
Face, and may there is interference with the part of engine interior in sensor.And some auto vendors beat according to oneself electromotor amount body
The electronics dipstick made is it is impossible to general in different type of machines, and still certainty of measurement is low.
And, existing conventional engine oil consumption measurement needs to release machine oil at electromotor oil discharge screw weighs, and is putting machine
The meeting being difficult to avoid in the manual operation that oil weighs occurs to spill machine oil to cause measurement error.
The present invention can flexibly tackle all kinds electromotor and variously-shaped oil sump, need not consider engine interior
Labyrinth, accurate measurement can be carried out to engine oil level, and can be by engine oil level and the oil level pair being added to electromotor
Should, can be used for the related experiment of engine research, development stage oil sump demarcation.Again because of engine oil level and the machine oil being added to electromotor
Amount corresponds, and electromotor runs the consumption to machine oil, can convert out by the change of engine oil level, the consumption to machine oil
Amount is accurately measured.

Add machine oil in flow container 3 to lower limit, sensor 5 is tested by second pressure and carries vent valve, the gas in emptying pressure guiding pipe
After re-record Pmin；The gas in machine oil one-way pump 7 and oil circuit is discharged before step S3；In step S3 in engine sump tank 1
After adding machine oil, the vent valve that sensor 4 carries, the gas in emptying pressure guiding pipe are tested by first pressure.
According to Ρ=ρ gh；
Pmax=ρ gHmax；
Pmin=ρ gHmin；
H=Hmax-Hmin
P21=ρ gH21；
P0=ρ gH0.
Calculate the engine oil quality flowing through dosing pump for the first time, volume read-out quality m that is, fluid reservoir 3 machine oil reduces1And volume V1
It is respectively：
m1=ρ V=ρ * (Pmax-P21)/ρg*πR2=π R2(Pmax-P21)/g
V1=m1/ ρ=π R2(Pmax-P21)/g/[(Pmax-Pmin)/Hg]=π R2H*(Pmax-P21)/(Pmax-Pmin).
Flow to the engine oil quality m of engine sump tank 1Send out 1And volume VSend out 1, in this example, it is removed into transparent glass tube
Part oil level is：mSend out 1=π R2(Pmax-P21)/g-πr2(P11-P0)/g, volume is：VSend out 1=π R2H*(Pmax-P21)/(Pmax-
Pmin)-πr2H*(P11-P0)/(Pmax-Pmin).When being not provided with Observation Blocks 2, enter the machine oil matter flowing to engine sump tank 1
Volume read-out quality m that amount is reduced with fluid reservoir 3 machine oil1Equal, can be calculated according to storage formula in the control module and start
The height that in oil pan 1, liquid level increases.
The height h that in engine sump tank 1, liquid level increases1(being that in thin glass tube, liquid level increases height in this example) is：h1
=H* (P11-P0)/(Pmax-Pmin).The machine oil matter being added to engine sump tank 1 every time can be calculated by above formula
Amount, machine oil volume and liquid level increase height, and these values are corresponded, and obtain engine oil quality or machine oil volume and liquid level
Increase the corresponding relation of height.
Oil consumption calculates
Electromotor run before detection module record now Observation Blocks 2 bottom engine oil pressure PConsume 0, hConsume 0=H* (PConsume 0-
P0)/(Pmax-Pmin), increased the corresponding relation of height with liquid level from engine oil quality with differential technique and calculate engine oil quality, be designated as
mConsume 0；
After electromotor end of run, after static a period of time, static 10min in the present embodiment, when machine oil liquid level stabilizing,
Record the engine oil pressure P of now Observation Blocks 2 bottomConsume 1, hConsume 1=H* (PConsume 1-P0)/(Pmax-Pmin), with differential technique from machine oil
Engine oil quality, engine oil quality m is calculated in quality and the corresponding relation of liquid level increase heightConsume 1；
mConsume 1-mConsume 0It is electromotor and run the oil consumption in this period.
Engine sump tank liquid level of the present invention is demarcated and engine oil consumption measuring method is passed through to add admittedly in fluid reservoir
Determine the machine oil of height, record the change value of pressure of liquid storage pot bottom, and this change value of pressure recordable, and can be according to electromotor
Oil sump base pressure value, directly extrapolates the height of oil sump engine oil level under without determination machine oil density case；Pass through
The change of pressure value can calculate the consumption of machine oil in the case of not releasing machine oil, in the excessive liquid level of oil consumption
Highly it is less than safe altitude alarm and remind whether electromotor out of service.This equipment can also be sent out in the test of machine oil recirculating oil quantity
Wave effect, such as regulation electromotor operates under specific operation and shuts down until next day after certain time, the recordable whole mistake of this equipment
The pressure change of engine sump tank in journey, extrapolates engine sump tank liquid level and oil level in whole process, so
The whole process that machine oil wall built-up amount and machine oil flow back to oil sump all can be recorded and supplies assay.

Engine oil pressure P to fluid reservoir (3) bottommin；
S2：Continue to add machine oil in fluid reservoir (3) to the upper limit, detection module detects the engine oil pressure of fluid reservoir (3) bottom
Pmax, in fluid reservoir (3), the distance between machine oil lower limit, upper limit are H；
S3：Machine oil is added to oil level liquid level in Observation Blocks (2) and to send out in from fuel oil supply unit to engine sump tank (1)
Motivation oil sump (1) bottom position is highly consistent, and the engine oil pressure that detection module detects Observation Blocks (2) bottom is
P0,
S4：Machine oil is added, detection module detects the machine of fluid reservoir (3) bottom in from fuel oil supply unit to engine sump tank (1)
Oil pressure P21, and Observation Blocks (2) bottom engine oil pressure P11；
S5：Repeat step S4, the engine oil pressure that detection module detects fluid reservoir 3 bottom is recorded as P successively22, P23, P24,
P25..P2n, and the engine oil pressure P of Observation Blocks 2 bottom12, P13, P14, P15...P1n；Until being added to engine sump tank (1)
Oil level reach control module given threshold.
