NOVELTY - Accurate real-time blending control method of ethanol-gasoline blending involves calculating volume of denatured fuel ethanol and gasoline component oil, setting instantaneous velocity ratio, controlling opening degree and opening control time of denatured fuel ethanol electrohydraulic valve and gasoline component oil electrohydraulic valve, respectively, calculating to-be-blended denatured fuel ethanol volume and to-be-blended gasoline component oil volume at real time, and adjusting opening degree and opening control time of electrohydraulic valves.    USE - Accurate real-time blending control method of ethanol-gasoline blending (claimed).    DETAILED DESCRIPTION - Accurate real-time blending control method of ethanol-gasoline blending involves calculating volume of denatured fuel ethanol and gasoline component oil based on target ratio, setting instantaneous velocity ratio of denatured fuel ethanol to gasoline component oil such that difference in velocity is within threshold value range, controlling opening degree and opening control time of denatured fuel ethanol electrohydraulic valve and gasoline component oil electrohydraulic valve, respectively based on the instantaneous velocity ratio, calculating to-be-blended denatured fuel ethanol volume and to-be-blended gasoline component oil volume at real time, and instantaneous velocity ratio of denatured fuel ethanol to gasoline component oil, such that difference value between predetermined instantaneous velocity ratio and target ratio is within predetermined threshold value range, and adjusting opening degree and opening control time of the denatured fuel ethanol electrohydraulic valve and the gasoline component oil electrohydraulic valve with respect to predetermined instantaneous velocity ratio until the ethanol gasoline blending is completed. The instantaneous velocity ratio is calculated based on ratio of to-be-blended denatured fuel ethanol amount with respect to total content of to-be-blended denatured fuel ethanol volume and to-be-blended gasoline component oil volume.
