| 摘要 |
The present invention relates to a device for varying the fuel-air mixture flow to an engine, and more particularly, to a device for varying the fuel-air mixture flow to the engine that can change the fuel-air mixture reaching the combustion chamber, thus improving fuel combustion and reducing pollution. A preferred embodiment of the invention delays spark timing based on engine speed and fuel-air mixture flow to further improve engine performance. The device comprises an actuator and a manipulator for changing the fuel-air mixture flow through an intake manifold into the engine in response to control signals transmitted from an electronic control unit.
