Description

Carburetor structure

This creation is about a carburetor structure, especially a carburetor device that maintains the degree of atomization stability as the first author.

According to the carburetor, it is widely used in various vehicles that require fuel engines, such as locomotives, automobiles or other types of vehicles. The carburetor uses the venturi principle and the Bainuoli principle to flow air into the oil. When the channel in the device is different, the pressure between the channel and the oil chamber is different due to the flow velocity of the air, and the air and fuel from the outside are mixed into a gas oil according to a preset ratio (air-fuel ratio) and introduced into the cylinder, and then the engine The ignition device ignites to detonate the oil and gas, and uses the energy generated by the combustion reaction to drive the crankshaft to drive the wheel to rotate.

However, since the conventional carburetor structure has a hole formed therein to form an atmospheric suction end and an engine intake end, the nozzle tube is connected to the hole edge of the atmospheric suction end and fixed, and the nozzle tube is fixed. Forming communication with the tunnel, so when the driver of the vehicle wants to change the amount of intake air entering the cylinder for combustion reaction (for example, the racer needs to operate the vehicle), the nozzle tube is fixed to the carburetor Therefore, the driver of the vehicle cannot replace the nozzles of different types (for example, nozzles with larger opening diameters) to meet the needs of different driving conditions, and the entire carburetor needs to be replaced with different inlet end apertures. Oiler.

When the engine intake end is assembled with the cylinder, it is caused by different cylinder volumes. The assembled apertures are different. Therefore, different cylinder volumes need to be set up with different sizes of carburetor, and the position of the throttle valve needs to be adjusted. Therefore, multiple sets of molds need to be opened to make the position of the oil path controlled by different cylinders. Differently, the starting position of the throttle opening is different and the atomization effect is unstable.

The reason is that the creators have made a lot of research and development and practical production experience in the relevant industries for many years, and then researched and improved the lack of prior technology, and provided a carburetor structure to achieve better practical value. Target person.

The main purpose of this creation is to provide a carburetor structure, especially for a carburetor device capable of maintaining the degree of atomization stability.

The purpose and function of the carburetor structure is achieved by the following technology: it mainly comprises a carburetor body, a first pipe is arranged on the carburetor body, and a first direction channel is formed in the first pipe. The first direction channel is an atmospheric suction end, the other side is an engine intake end, and the carburetor body is provided with a second pipe, the second pipe forms a second direction channel, and the second direction channel and the second direction The first direction channel is vertical, and the second direction channel is provided with a throttle valve corresponding to the air intake amount corresponding to the atmospheric suction end of the first direction channel, wherein the first direction channel aperture disposed in the first pipe is a throttle valve The starting point of the opening degree is the reference, and the center of the first direction channel aperture is eccentric with respect to the center of the outer diameter of the first pipe; thereby, the kinetic energy of the same starting point can improve the commonality of the internal mechanism and the parts, and can not only share The mold, and the length of the pipeline for the oil atomization of different sizes of carburetor is the same, and the atomization effect is stable.

The carburetor structure as described above, wherein a screwing portion is disposed outside the second pipe, and the screwing portion directly corresponds to the screwing and fixing the upper cover to achieve the effect of quickly assembling the locking.

The carburetor structure as described above, wherein an independent air inlet hole is disposed at an outer periphery of the air suction end, so that the air flow can be independently introduced, and the air intake amount and the atomization degree are not affected by the flow velocity of the air intake hood at the air suction end. The mixture is more stable than the effect.

The carburetor structure as described above, wherein the port of the atmospheric suction end is capable of correspondingly disassembling a different type of shroud, such as a cover body having a long wind guiding distance (short), a cover body enlarging a concentrated shape, and the like. The length of the intake pulse wave will be different depending on the length, and the flow rate and the intake air amount will be different, which is required to meet different vehicle conditions.
