Abstract:
1. An engine device, comprising: an engine, comprising a piston and a cylinder, wherein the piston is arranged in the cylinder and moves between a top dead center and a bottom dead center; a power generating portion, annularly disposed on the periphery of the cylinder and comprising a power generating rotor and a power generating stator, wherein the power generating rotor moves in a rectilinear motion, and the power generating portion generates electric power when the power generating rotor and the power generating stator make a relative movement; a motor portion, annularly disposed on the periphery of the cylinder and comprising a motor rotor and a motor stator, wherein the motor rotor moves in a rectilinear motion, and the motor portion actuates the motor rotor and the motor stator to produce a relative movement when the piston is located at the bottom dead center; and a transmission mechanism, connected between the piston, the motor rotor, and the power generating rotor, wherein when the piston moves from the top dead center towards the bottom dead center, the transmission mechanism drives the power generating rotor to move correspondingly in a direction opposite to that of the piston and enables the power generating rotor and the power generating stator to produce the relative movement, and when the motor rotor and the motor stator produce the relative movement, the motor rotor moves the piston from the bottom dead center towards the top dead center through the transmission mechanism.
