Method for reducing fuel engine transient output power fluctuation

The invention relates to a method for reducing fuel engine transient output power fluctuation. A power generation device and a driving device are coaxially installed on a three-cylinder engine, one part of heat produced after the three-cylinder engine works is directly converted into mechanical energy for motor rotation, the other part is converted into electric energy, rectified and stored in anenergy storage device, a motor driver is used for enabling the driving device to convert electric energy stored in the energy storage device to mechanical energy for motor rotation, and at the moment,the effect that the driving device converts electric energy into mechanical energy is equivalent to increasing the number of air cylinders in an engine for work. Peak elimination and compensation areachieved for engine output power fluctuation, and engine output power is more stable. 本发明涉及种降低燃油发动机瞬态输出功率波动的方法，将发电装置及驱动装置同轴安装于三缸发动机上，所述三缸发动机作功后产生的热能部分直接转换为机械能用于电动机转动，另部分将转换为电能，经整流后存储于储能装置中；再利用电机驱动器使驱动装置将储能装置中储存的电能转换为机械能用于电动机转动
