What are the systems of Honda carburetor?

In the process of gas flow, as long as the cross-section of the channel remains unchanged, the gas flow rate will remain unchanged. The Honda carburetor uses this physical principle to set a throat on the air flow channel. The Honda carburetor changes the air pressure difference of the oil-gas interface by changing the diameter of the throat to help the oil-gas mixing and ejection for engine combustion.

What are the systems of Honda carburetor?

The main oil supply system is the main oil supply system of the Honda carburetor. There are three common main oil system correction methods, which are, compensation with infiltrated air, changing the area of main measuring hole with oil needle, and changing the area of throat and main orifice at the same time. The first method is widely used.

When the internal combustion engine operates but does not work externally, it is called idle operation. The throttle is close to closing, and the vacuum at the throat of Honda carburetor cannot suck out and atomize the fuel. Therefore, an idle nozzle is set behind the throttle to suck out the fuel by using the vacuum.

In order to meet the economic requirements, the main oil system of Honda carburetor supplies thinner mixture under most working conditions. When the throttle is close to fully open, the maximum power is required, which requires the supply of rich mixture. Fuel economizers are usually used to achieve this purpose.

What does the main oil supply system of Honda carburetor contain?

The main oil supply system of Honda carburetor is a working system that provides combustible mixture to the working conditions in the frequent working area of the engine. It is mainly composed of main measuring needle, plunger, main nozzle, and main nozzle.  

Between idle speed and full speed, regardless of the setting position of the plunger, the main oil supply system of Honda carburetor provides the engine with combustible mixture with a certain oil-gas mixture ratio, which only changes the amount of oil and gas supplied to the engine. The amount of air is determined by the rise and fall of the plunger. The lifting of the main measuring needle determines the amount of oil supply. The air-fuel ratio of the main oil supply system is adjusted by changing the position of the main measuring needle on the plunger.

How does Honda carburetor provide thicker combustible mixture to the engine?

The starting oil system of Honda carburetor is a system that provides a thicker fuel mixture to the engine when the engine is in cold weather and the idle oil system cannot ensure the reliable start of the engine.

Choke engine can inhale both air and gasoline through Honda carburetor. If the amount of inhaled air can be limited, relatively more gasoline will be inhaled into the engine. A butterfly valve is installed in the Honda carburetor as a choke to limit the air flow to enrich the mixture.

The enrichment valve designs a separate enrichment pipeline in the Honda carburetor, which is similar to the idle mixture path. But the size of the enrichment path is larger than that of the idle path. The position is behind the plunger and before the engine. When the throttle is closed, the enrichment valve opens. Due to the vacuum suction in the throat, the Honda carburetor sucks oil directly from the enrichment nozzle.

Honda carburetors are equipped with a button valve on the upper part of the float chamber. Press the valve to press the float and raise the oil level of the float chamber to enrich the mixture.
