Method for testing and evaluating influence of low-octane gasoline on torque model

The invention discloses a method for testing and evaluating the influence of low-octane gasoline on a torque model, and belongs to the technical field of automobile tests.The method comprises the steps that S1, test conditions and environments are confirmed; s2, judging whether the test conditions and environments are the same as those of the octane number Y gasoline calibration test conditions and environments or not, and if yes, evaluating by adopting the scheme I; if not, the scheme II is adopted for evaluation; through the test and evaluation method provided by the invention, whether the torque model precision of the engine subjected to high-grade gasoline calibration meets the requirement when the low-octane gasoline is used is checked, and the influence range and degree of the engine are mastered. The method is helpful for quickly judging the range of the working condition points, needing to be calibrated and matched again, of the torque model after the low-octane gasoline is used, and mastering the dev
