Problems solved by technology

[0002] At present, the engine torque controllability of ordinary fuel vehicles is low and the high-efficiency zone is narrow. In order to improve the efficiency, although the gearbox is used to adjust the torque and speed to make the engine work in the high-efficiency zone as much as possible, the efficiency is still very low.
