  • Patent number: 8511649
    Abstract: A model engine carburetor capable of adjusting oil automatically when decelerating is mounted on a model engine. The model engine carburetor has a first adjustment room and a second adjustment room. The first adjustment room and the second adjustment are separated by an elastic membrane. When the model engine is decelerated at a very short time from a high speed, the model engine will generate negative pressure to draw out the air in the first adjustment room and the elastic membrane will be deformed to generate vacuum suction. The overmuch fuel oil is drawn to the second adjustment room to adjust the ratio of the oil gas. The model engine can run smoothly when the speed is decelerated at a very short time.
