Pressure type: A hydraulic mechanical device that forms a closed delivery system from the fuel pump to the discharge nozzle. It measures the fuel flowing through the fixed injection device according to the air flow through the throttle and consumes the fuel under positive pressure. The pressure carburetors are obviously different from the floating carburetors because they do not use the floating chamber for draining oil or the suction oil extractor in combination with the discharge nozzle in the venturi.
Floating type: It basically consists of a main air channel through which the engine draws air. It is not only a fuel consumption control device related to air flow, but also a device that can adjust the amount of oil-air mixture delivered to the engine cylinders.
