Abstract
An engine device includes an engine, a power generating portion, a motor portion, and a transmission mechanism. The engine includes a piston and a cylinder, and the piston is arranged in the cylinder and moves back and forth between a top dead center and a bottom dead center. The power generating portion and the motor portion are annularly disposed on the periphery of the cylinder. When the piston moves from the top dead center towards the bottom dead center, the transmission mechanism drives a power generating rotor of the power generating portion to move correspondingly in a direction opposite to that of the piston and enables the power generating portion to generate electric power. When the piston is located at the bottom dead center, the motor portion actuates a motor rotor to move, and pushes the piston to move towards the top dead center through the transmission mechanism.
