Description
[technical field]
The present invention relates to testing octane number of gasoline technical field, specifically a kind of method of gasoline octane number tester and the maximum knock intensity oil-gas ratio of observing and controlling.
[background technology]
The mensuration of octane number is burnt in real time by gasoline octane number tester to run the maximum knock index of rear acquisition, compare with the maximum knock index of height two kinds of standard oil samples again and calculate, the acquisition of maximum knock index produces under the state of suitable air with oil product mixed oil and gas ratio, therefore, determine that maximum knock intensity mixed oil and gas is than the key being testing octane number of gasoline.
When gasoline octane number tester measures octane number, prior art have employed syphon feed and electric jet fuel feeding two kinds of methods substantially.Electric jet fuel feeding is by detecting the parameter such as oil density and oxygen content in air, automatically control to expect to oil mass by the oil-gas ratin preset reach maximum pinking by calculating, this method of electric jet fuel feeding is satisfactory for result, accurately efficient, but its system complex, check point is many, control and execution unit running frequency high, be easier to the instability bringing system, involve great expense simultaneously, cost is higher.
Syphon feed is the scale being realized the mixed oil and gas needed for engine combustion by the height of pasta liquid level, the method is simple and practical, cheap, but the fuel head that its method of adjustment obtaining maximum knock intensity oil-gas ratio is manual observation and manually adjusts in carburetor glass observer, to expect to obtain maximum pinking, this method regulating time is long, labour intensity is large, and regulate the change direction of direction and pasta initial and inconsistent when operating, easy generation fluctuation, cause artificial interference factor in mensuration effect larger, consistance is poor, do not reach desirable measurement result.
[summary of the invention]
The object of the invention is to solve in prior art the technical matters that when obtaining maximum knock intensity oil-gas ratio by the method for syphon feed thus measure octane number, regulating time is long, labour intensity is large, mensuration effect is undesirable, a kind of auto-control by oil product liquid level is provided to realize maximum knock intensity oil-gas ratio, the method for the gasoline octane number tester of efficient, accurate, full automatic mensuration octane number and the maximum knock intensity oil-gas ratio of observing and controlling.
To achieve these goals, a kind of gasoline octane number tester is provided, comprise oil product cup support, elevating mechanism, fixed support, gasoline octane number tester body and knock intensity measuring instrument, described elevating mechanism side is flexibly connected oil product cup support, elevating mechanism opposite side is fixedly connected with fixed support side, fixed support opposite side connects gasoline octane number tester body, gasoline octane number tester body carburetor oil-in connects oil product cup frame bottom oil-out by oil way flexible pipe, and control device connects elevating mechanism and knock intensity measuring instrument.
Described oil product cup support adopts heavy wool product cup support or single oil product cup support, described heavy wool product cup support is that a framed structure is provided with some oil product cups and Multi-oil circuit electronic switch valve, each oil product cup is connected with each path flexible pipe of Multi-oil circuit electronic switch valve, and described single oil product cup support is that a framed structure is provided with an oil product cup.
Described oil product cup support is provided with carburetor oil-gauge glass observer.
A kind of method adopting the maximum knock intensity oil-gas ratio of above-mentioned gasoline octane number tester observing and controlling, the method of the maximum knock intensity oil-gas ratio of described gasoline octane number tester observing and controlling is the method automatically regulating pasta liquid level, according to the current knock index that knock intensity measuring instrument records, pasta liquid level is changed by automatically regulating elevating mechanism, knock intensity measuring instrument obtains the knock index behind change in elevation position, knock index change is analyzed: if knock index changes towards little direction, then control break pasta liquid level changes round about, if knock index changes towards large direction, then continue to change pasta liquid level to equidirectional, till knock index changes to little direction again, maximum knock index point is obtained according to pasta liquid level position and knock index data query, again the adjustment of pasta liquid level is caused on the pasta liquid level location point recording this maximum knock index point association, whether the maximum knock index of this knock index of compound and record is close again, as error is larger, then repeat adjustment again, otherwise, then think and have found maximum knock intensity oil-gas ratio pasta liquid level point.
The method of the maximum knock intensity oil-gas ratio of above-mentioned a kind of observing and controlling, the method of described automatic adjustment pasta liquid level is as follows: elevating mechanism drives oil product cup support to move up and down, change the fuel head in carburetor oil-gauge glass observer on oil product cup support, and the pasta in carburetor oil-gauge glass observer is changeless relatively in glass observer, by the outflow of the float buoyancy control oil product in oil product, keep a pasta balance, elevating mechanism drives the oil product cup support of fixing carburetor oil-gauge glass viewer automatically to regulate with regard to controllable pasta liquid level, thus change the siphon pressure of oil product, adjustment oil gas mixing ratio.
Described heavy wool product cup support only uses the oil product of an oil product cup when applying, by Multi-oil circuit electronic switch Vavle switching to the oil product cup of specifying, the pasta liquid level of its maximum knock intensity oil-gas ratio of the oil product in each oil product cup is different, the pasta liquid level control position of control device to its maximum knock intensity oil-gas ratio of the oil product on each road is remembered in use, when being switched to the application of this road again, directly adjust to this memory area, more automatically regulate pasta liquid level by the method for the maximum knock intensity oil-gas ratio of gasoline octane number tester observing and controlling.
The present invention compared with the existing technology, its advantage is: adopt and realize maximum knock intensity oil-gas ratio by the auto-control of oil product liquid level, repeatability is stable, finding speed is fast, and larger decreases labour intensity, efficient, accurate, full automatic mensuration octane number; Adopt heavy wool product cup support, control device can be remembered the pasta liquid level control position of its maximum knock intensity oil-gas ratio of oil product on each road in heavy wool product cup, then when being switched to the application of this road, is adjustable to memory area, decrease regulating time, successful.
