The structure is simple, the manufacturing cost is low, maintenance is convenient and inexpensive, and parts are affordable. The main components are few; regular inspection and replacement of filters, oil, etc. are sufficient, without complex tools or professional technicians. Conventional workshops can handle necessary repairs. By relying on the vacuum effect generated by the engine's intake, gasoline is mixed with air, making active and precise control of fuel supply difficult, resulting in relatively high fuel consumption. By utilizing the kinetic energy of the inhaled airflow, gasoline atomization can be achieved, and the corresponding mixture concentration can be automatically measured and delivered according to the engine's operating conditions. The throttle is cable-controlled, and when the driver twists the throttle handle, the throttle valve reacts immediately, with almost no power delay and a direct acceleration experience.
