Description
Technical field
The present invention relates to the automobile fuel consumption field of measuring technique, especially is non-intervention engine fuel system, through the high precision automobile fuel consumption measuring technique of externally measured mode.
Background technology
At present; Domestic and international existing automobile fuel consumption metering system mainly is an insertion type; Carry out fuel consumption measurement through access flow measurement mechanism in engine fuel system; This mode need be dismantled engine fuel system, has influenced the installation accuracy and the reliability of engine fuel system, and measuring accuracy also is difficult to improve; Non-intervention metering systems such as adopting ultrasound wave, Flame Image Process is also arranged, but these modes or complex structure, price are higher, or measuring accuracy does not reach requirement, still is among the development.
Summary of the invention
The present invention is the deficiency that overcomes existing automobile fuel consumption metering system; A kind of non-intervention type, convenient and swift, high-precision automobile fuel consumption measuring system are proposed; Need not engine fuel system is dismantled, avoided engine fuel system is caused damage, the while is easy for installation, precision is high.
Said non-intervention type high precision automobile fuel consumption measuring system is mainly by pressure pipe joint 1, pneumatic tube 2, and luminescent device 3, fluid column 4, light sensor spare 5, liquid column pipe 6, liquid column pipe and pressure pipe joint 7, controller 8, data presentation pen recorder 9 is formed, and is as shown in the figure.The flexible pipe of pneumatic tube 2 for having certain degree of hardness; One end is inserted in the automobile fuel filler mouth through the pressure pipe joint 1 of sealing; The other end is connected through sealing adaptor 7 and liquid column pipe 6 lower ends, and the air in the fuel tank communicates with liquid column pipe 6 through pneumatic tube 2, does not communicate with outside air; Like this when oil mass in the fuel tank reduces; Cause corresponding the reducing of fuel tank, pneumatic tube 2 and liquid column pipe 6 internal gas pressures, thereby make liquid column pipe 6 interior fluid columns 4 move down, so the variation of liquid column pipe 6 interior fluid column 4 positions has reflected the variation of oil mass in the fuel tank; Liquid column pipe 6 is between luminescent device 3 and light sensor spare 5; A part of light that luminescent device sends is owing to fluid column 4 stops according on the light sensor spare 5 less than the opposite; The position that light sensor spare 5 will not receive light sends controller to; Can calculate the fuel consumption of measuring in the beginning and ending time according to the variable quantity of measuring beginning and ending time fluid column 4 positions; Last controller should value show on screen through measurement data displayed record device 9, and can directly be transferred to and carry out data processing and storage in the computing machine.
Said non-intervention type high precision automobile fuel consumption measuring system; It is characterized in that through fluid column 4 when the initial Measuring Time in liquid column pipe 6 reference position and by Measuring Time the time rest position of fluid column 4 in liquid column pipe 6 poor; The transversal area of a circle with liquid column pipe 6; Can directly calculate the oil consumption volume of engine in the beginning and ending time, the fuel consumption that promptly from fuel tank, flows out comprehensively, has accurately reflected the fuel consumption during engine is from the fuel tank to the injection process; Measuring Time can accurately be set through controller, has more guaranteed measuring accuracy.
Said non-intervention type high precision automobile fuel consumption measuring system is characterized in that through reducing the diameter of liquid column pipe 6, can improve and measure sensitivity and precision, reaches various vehicle oil consumption and measures the desired measuring accuracy of project.
Description of drawings
Fig. 1 non-intervention type high precision automobile fuel consumption measuring system.Among the figure, 1-pressure pipe joint, 2-pneumatic tube, 3-luminescent device, 4-fluid column, 5-light sensor spare, 6-liquid column pipe, 7-liquid column pipe and pressure pipe joint, 8-controller, 9-data presentation pen recorder.
Fig. 2 non-intervention type high precision automobile fuel consumption measuring system fuel consumption is calculated principle.Among the figure, the 10-seal, other description of symbols is the same.
Embodiment
Specify the present invention below in conjunction with accompanying drawing.
Fuel consumption measurement system pressure pipe joint 1 when not using seals with sealing-plug respectively with liquid column pipe 6, prevents that fluid column 4 from leaking; Before measuring oil consumption, open the sealing-plug 10 of liquid column pipe 6, the air bag at extruding pneumatic tube 2 middle parts is adjusted to the upper limit position of liquid column pipe 6, the sealing-plug 10 of confining liquid column jecket 6 with fluid column 4; Open the sealing-plug of pressure pipe joint 1 end, unclamp the air bag at pneumatic tube 2 middle parts, this moment, fluid column 4 still rested on the upper limit position of liquid column pipe 6; Open the automobile fuel filler mouth, insert pressure pipe joint 1, and confirm connection, good seal; Open the sealing-plug 10 of liquid column pipe 6, starting engine can be measured engine oil consumption and time relation, and the engine operating condition that detects according to need is got a certain operating mode time period and can be calculated fuel consumption measurement.
Referring to Fig. 2, the computing method of the oil consumption G (g) in a certain operating mode time period are following:
G＝πR
2(h
1-h
2)γ
Wherein, R is the liquid column pipe radius, m; h
1Be fluid column reference position height, m; h
2Be fluid column rest position height, m; γ is the fuel oil specific mass, g/m
