Description
Technical field
The present invention relates to a kind of automobile fuel consumption measuring method more particularly to a kind of gasoline engine oil consumption measuring methods.
Background technology
Evaluation for automobile fuel ecomomy, come generally by vehicle fuel consumption test it is determining, it be use
To evaluate the important ginseng of the comprehensive parameter of vehicle in use technology status and repair quality and diagnosis and analysis vehicle failure
It examines.The accuracy of fuel consumption meter directly affects the evaluation of vehicle economy energy, the fuel consumption meter use of existing passenger car and commercial car
The coriolis mass flowmeters of higher accuracy.
Existing gasoline engine oil consumption measuring method is by fuel consumption meter（Flowmeter）Mounted on pressure regulator valve between engine
In oil circuit, that is, when automobile engine is started to work, fuel oil flows into pressure regulator valve after fuel tank comes out by fuel pump, at this time
Fuel oil enters mass flow type fuel consumption meter after pressure regulator valve controls, then is measured through mass flow type fuel consumption meter and flow into engine work
Oil mass.But in the oil circuit of pressure regulator valve and engine, there are the region of the small flow of low speed, in low speed small flow area oil
It is larger to consume instrument measurement error, 3%-5% is can reach, so as to affect the precision for gasoline engine fuel consumption measurement.
Invention content
The purpose of the present invention is to provide a kind of gasoline engine oil consumption measuring method, which can accurately grasp fuel oil
Consumption preferably grasps oil consumption and generator operating conditions.
In order to realize above-mentioned technical purpose, the present invention adopts the following technical scheme that：
A kind of gasoline engine oil consumption measuring method, fuel oil through fuel tank flow into fuel pump and pressure regulator valve oil circuit into oil flowmeter,
Oil inlet flowmeter measures oil inlet quantity A at this time, and for fuel oil after pressure regulator valve controls, a part flows into engine work, part reflux
Enter fuel tank, oil return measures recirculating oil quantity B, pass through oil inlet by pressure regulator valve and the return flow meter in tank oiling channel oil, return flow meter
Numerical value measured by flowmeter and return flow meter subtracts, and obtains the consumption X of fuel oil, i.e. X=A-B.
It is described to form double mass flow meter measurement systems into oil flowmeter 3 and return flow meter 6.
Gasoline engine oil consumption measuring method of the present invention is used is installed into oil flowmeter in fuel pump to pressure regulator valve oil circuit, is adjusting
In oil return circuit after valve, i.e. the oil return circuit of pressure regulator valve to fuel tank installs back oil flowmeter, is obtained by oil inlet flow measurement
Oil inlet quantity subtracts the recirculating oil quantity that return flow measures, and obtains the consumption of fuel oil.And into oil flowmeter and return flow meter
The position of double mass flow meter measurement systems installation of composition is in big flow region, so as to avoid low speed Small flowrate measurement
Caused by error it is larger the problem of.
Compared with prior art, advantage is gasoline engine oil consumption measuring method of the present invention：Gasoline can not changed
Under the premise of machine component, low speed small flow area is avoided, improves the accuracy for measuring oil consumption, preferably to grasp oil consumption situation,
And the operating condition of engine, so as to reduce single mass flowmenter（Fuel consumption meter）It is produced when low speed small flow area measures
Error.
Gasoline engine oil consumption measuring method of the present invention can not change gasoline engine using easy, energy quick obtaining data
Under the premise of component, the accuracy for measuring oil consumption is improved.
Description of the drawings
Fig. 1 is gasoline engine oil consumption measuring method schematic diagram of the present invention.
In figure：1 fuel tank, 2 fuel pumps, 3 into oil flowmeter, 4 pressure regulator valves, 5 engines, 6 return flow meters.
Specific embodiment
The invention will be further described in the following with reference to the drawings and specific embodiments.
Referring to Fig. 1, a kind of gasoline engine oil consumption measuring method, when automobile engine is started to work, fuel oil is flowed into through fuel tank 1
In fuel pump 2 and 4 oil circuit of pressure regulator valve into oil flowmeter 3, measure oil inlet quantity A into oil flowmeter 3 at this time, fuel oil is through pressure regulator valve
After 4 controls, a part flows into engine 5 and works, and a part passes back into fuel tank 1, especially in low engine speed operation or idling
When, the fuel oil of burning is less needed for engine.Oil return is by pressure regulator valve 4 and the return flow meter 6 in 1 oil circuit of fuel tank, oil return stream
Gauge 6 measures recirculating oil quantity B, by subtracting into the numerical value measured by oil flowmeter 3 and return flow meter 6, obtains disappearing for fuel oil
Consumption X, i.e. X=A-B.It is described to form double mass flow meter measurement systems into oil flowmeter 3 and return flow meter 6, and into oil stream
The position that gauge 3 and return flow meter 6 are installed is in big flow region.
Compare through measured data, the fuel consumption measuring error of double mass flow meter measurement systematic surveys is less than single mass flowmenter and measures
The fuel consumption measuring error obtained.The result measured through double mass flow meter measurement systems has more accurately been grasped oil consumption situation and has been started
Machine operating condition.Single mass flowmenter generated error when low speed small flow area measures is reduced so as to reach.
Specific measurement procedure：
1st, wiring, including power cord, cooling system line, flowmeter associated components（Transformer, sensor）Line and display
Shield line, fuel distribution tube, each connector of flowmeter is connected to suitable fuel port；
2nd, flowmeter associated components are transferred to suitable state；Start engine, open the valve of oil inlet and oil return road flowmeter, exclude
After air, the valve of flowmeter is closed, carries out zero adjustment；
3rd, it opens and flows to double mass flow meter measurement systems, start engine, measure；
4th, the temperature of coolant is set；
5th, flowmeter internal pressure is laid down, each valve of flowmeter is closed, obtains data.
The foregoing is merely a prefered embodiment of the invention, is not intended to limit the scope of the present invention, therefore, it is all
Any modification, equivalent replacement, improvement and so within the spirit and principles in the present invention should be included in the protection model of the present invention
Within enclosing.
