Abstract

The invention discloses an oil index tester. Firstly, the octane number of a standard oil sample or cetane number data of diesel is acquired, and the dielectric constant of the corresponding oil is automatically tested; after all sample information is entered, the tester checks the rationality of the sample first, and then operates with a polynomial least squares method and compares errors of primary, secondary and cubic polynomials; relatively low power is selected within an allowable range so as to reduce the complexity of calculation, and all parameters of a formula are automatically determined; after the formula is generated, a user can use the regression formula for subsequent quick oil testing. Through adoption of the technical scheme, the problems of large error, large workload andhigh labor cost caused by manual regression and manual calibration in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of octane number measuring instruments, in particular to an oil index measuring instrument. Background technique [0002] The octane number of gasoline is a functional index to measure the anti-knocking combustion ability of gasoline in the cylinder, and a high value indicates good anti-knocking performance. When gasoline is normally burned in the cylinder, the flame propagation speed is 10-20m / s, and it can reach 1500-2000m / s during detonation combustion. The latter will cause the temperature of the cylinder to rise sharply, the combustion of gasoline will not be complete, and the machine will vibrate strongly, which will reduce the output power and damage the machine parts. [0003] Hydrocarbons with different chemical structures have different anti-knock capabilities. Isooctane (2,2,4-trimethylpentane) has better anti-knock properties, and its octane number is given as 100. The anti-knock property of n...
