When the CVT of the composite guide vane adjustable hydraulic torque converter of the present invention is used, the input power, input speed and its load of the engine are assumed to be constant, that is, the speed and torque of the input shaft 1 are constant, and before the automobile starts, The rotational speed of the output shaft 9 is zero. When the car starts, due to the large resistance and the effect of the one-way clutch 4, the converging ring gear 28 is stationary, and the converging gear 27 transfers the energy transmitted from the input shaft 1 through various components. The torque is then transmitted to the confluence planetary carrier 29, so that the confluence planetary carrier 29 slows down and increases the torque, and then is transmitted to the confluence input ring gear 32, and confluence with the torque transmitted to the confluence input gear 31 to the output planetary carrier 33, and finally transmitted To the output shaft 9, when the traction generated by the drive train to the driving wheels is enough to overcome the starting resistance of the car, the car starts and starts to accelerate.
