1. one kind is utilized mid-infrared light spectral technology quick identification motor fuel kind and trade mark method, comprises the steps:

  • The first step;

    every class A fuel A is collected the sample of some as training set;

    Second step;

    measure each sample mid infrared absorption spectrum of training set;

    The 3rd goes on foot;

    after infrared spectrum is passed through pre-service, principal component analysis (PCA) successively, select for use principal component scores as the identification variable, set up the fuel model of cognition in conjunction with the mahalanobis distance method;

    The 4th step;

    for motor fuel sample to be measured, at first measure its infrared absorption spectrum, then by computing machine in conjunction with spectrum and the model set up, the quick identification fuel type and the trade mark automatically.
