fuel level gauge carburetor
The automobile carburetor is between the intake pipe and the air filter. The function of the carburetor is to use the kinetic energy of the intake air flow to realize the atomization of gasoline. The carburetor will automatically mix the corresponding concentration and output the corresponding amount of mixture according to the requirements of different working conditions of the engine. In order to make the mixture mixed evenly, the carburetor also has the effect of atomizing the fuel for the normal operation of the machine. The carburetor mixing ratio adjustment method is as follows:
1. First, check the connection tightness of the connecting parts related to the carburetor to ensure that the carburetor can inhale normally, without air leakage and blocking;
2. Turn the carburetor mixing ratio screw clockwise to the end, and then turn 1.5 circles counterclockwise to start the engine. Allow the engine to warm up for 10 minutes to make the engine reach the normal operating temperature. Adjust the carburetor idle speed adjusting screw to make the engine rotate at the lowest speed and keep it running;
3.Repeatedly adjust the carburetor mixing ratio screw left and right to make the engine speed reach the maximum. In this process, some friends will find that after the mixing ratio screw is adjusted to a certain position, rotate the mixing ratio screw counterclockwise, and the idle speed will not change again. At this time, the mixing ratio screw can stay at the position when the idle speed is just adjusted to the maximum.
The working principle of the carburetor is as follows: 1. The air from the outside enters the carburetor after being filtered. The air intake is controlled by the change of the choke position. 2. The air rushes through the throat in the carburetor to produce a suction force to suck the fuel from the float chamber through the nozzle and atomize it. 3. After atomized fuel and air are mixed, they are inhaled by the cylinder through the intake manifold. The intake of the mixture is controlled by an accelerator pedal, which is located in the carburetor. 4. 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 filled with gasoline, the float floats up and uses its needle valve to block the oil inlet.
