Under the normal working condition of the engine, the Kawasaki carburetor is required to supply the mixture that changes from rich to lean with the increase of load under small and medium load. At full load, the mixture in the Kawasaki carburetor is required to change from lean to rich. In order to meet these requirements, the Kawasaki carburetor is equipped with a series of mixed gas concentration compensation devices.

What are the features of Kawasaki carburetor?
The structure of Kawasaki carburetor uses the negative pressure of intake air to absorb fuel. The oil supply structure uses various throttling and pressure relief principles to adjust the oil concentration. The mechanical structure of Kawasaki carburetor is relatively simple and clear, which can be seen by the naked eye and is convenient for outdoor maintenance.
The charging and mixture distribution of Kawasaki carburetor to the cylinder is not ideal, which affects the improvement of the power performance and economic performance of the engine. The Kawasaki carburetor is very unfavorable to meeting the ranking requirements. Therefore, the carburetor is almost replaced by EFI at present.
The air from the outside enters the Kawasaki carburetor after being filtered. The air intake is controlled by the change of choke position. The air rushes through the throat in the Kawasaki carburetor to generate suction, sucks the fuel out of the float chamber through the nozzle and atomizes it. The atomized fuel and air are mixed and sucked into the cylinder through the intake manifold. The intake of the mixture is controlled by an accelerator pedal, which is controlled by the accelerator in the Kawasaki carburetor. The amount of oil pumped into the float chamber by the gasoline pump is controlled by the float in the float chamber. The float rises and falls with the amount of oil in the float chamber. When the float chamber is full of gasoline, the float floats up and its needle valve blocks the oil inlet. By controlling the throttle opening to change the engine speed, the mixture concentration gradually thickens with the throttle opening.
Kawasaki carburetor often varies over a wide range. Before starting and waiting for the green light at the intersection, the engine runs at idle speed. At this time, the load is zero, the throttle opening is the smallest and the speed is the lowest. When the car climbs with full load, the accelerator is fully open but the speed is not high. When driving on a flat road, the accelerator does not have to be fully opened, the engine emits medium load, and the speed is medium. When driving on the highway, the engine may be at full load and reach the maximum speed.
Under such complex working conditions, the requirements for mixture in the Kawasaki carburetor cannot be the same. Under idle speed and small load, the former requires that the mixture must be very thick, while the latter requires that the concentration gradually become thin. Under medium load, in order to save fuel, the Kawasaki carburetor is required to supply the mixer with the lowest fuel consumption rate. Under full load to make the engine produce maximum power, the Kawasaki carburetor is required to provide rich mixture. In addition, if the car starts, it is required to have a thicker mixture in the Kawasaki carburetor. When accelerating, the Kawasaki carburetor is required to supply additional oil when the throttle is suddenly opened.
