Abstract: An electromagnetic continuously variable transmission system is provided, including: a pulley, including a first disc having an axial sleeve and a second disc, the first disc having a plurality of grooves which extend radially at one side, pulley balls being slidably received within respective ones of the grooves, the first disc having a first slope at another side, the second disc being located by the side of the first disc with the grooves; a driving shaft, disposed in the axial sleeve and the second disc, the first disc being axially slidable relative to the driving shaft; an electromagnetic assembly, disposed on the pulley, including electromagnets spacingly arranged in a part of the grooves; when each of the electromagnets is electrified and generate magnetism, each of the electromagnets magnetically attracts one of the pulley balls toward the axial sleeve.

Abstract: A low impedance power disc is provided. The power disc is connected to a crankshaft of an engine, and includes a rotor, a connecting shaft, and a permanent magnet. The rotor is disposed separately from the permanent magnet. The connecting shaft is locked inside the rotor. A unidirectional bearing is provided and fitted on the connecting shaft. The permanent magnet is fitted on the unidirectional bearing. When the engine is running, the rotor and the permanent magnet are rotated at the same speed to generate electricity and supply the electricity to the vehicle and to charge the battery. When the engine decelerates, the rotor and the connecting shaft are decelerated synchronously with the engine, while the permanent magnet and the unidirectional bearing are continuously rotated at the speed before deceleration in order to facilitate the engine to accelerate again, so that the rotor can be quickly rotated.

Abstract: Disclosed is an engine temperature regulating device installed to a cool air inlet of a casing of an engine. The engine temperature regulating device includes a power source, a link rod module connected to the power source, a control module and a fan cover module including a fixed casing and a movable casing. The control module is provided for detecting a temperature when the engine is turned on to control the power source to drive the link rod module, so as to control the rotation of the connected movable casing and further adjust an air intake hole of the fixed casing to a smooth or obscured state.
