Embodiment Construction

[0019] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0020] refer to figure 1 , figure 2 and image 3 , a carburetor for an outboard motor provided with a rapid acceleration and enrichment device, comprising a carburetor body 1, a mixing chamber 7 and a float chamber 10 are arranged in the carburetor body. The carburetor body 1 is provided with a rapid acceleration enrichment device. The rapid acceleration and enrichment device includes a pressure-taking pipe 2 communicated with the mixing chamber 7 , and an acceleration pump cover cavity 5 communicated with the pressure-detection pipe 2 . The accelerator pump cover cavity 5 is provided with a diaphragm 9 and a diaphragm return spring 6 . The diaphragm 9 is arranged in the middle of the accelerator pump cover cavity 5 , and the diaphragm 9 divides the accelerator pump cover cavity 5 into a negative pressure chamber 51 and a diaphragm chamber 52 . One ...

Abstract

The invention relates to a carburetor for an outboard motor equipped with a rapid acceleration and thickening device, which comprises a carburetor body in which a mixing chamber and a float chamber are arranged. The carburetor body is provided with a rapid acceleration and thickening device. The rapid acceleration and enrichment device includes a pressure-taking pipe communicated with the mixing chamber, and an acceleration pump cover cavity communicated with the pressure-taking pipe. A diaphragm and a diaphragm return spring are arranged in the cavity of the accelerator pump cover. One end of the diaphragm return spring is pushed against the inner wall of the negative pressure chamber, and the other end of the diaphragm return spring is pushed against the diaphragm. There is an oil inlet hole in the middle of the partition between the diaphragm chamber and the float chamber. Equipped with a one-way valve. The lower part of the diaphragm cavity is provided with an oil outlet, and the oil outlet is connected with an oil outlet pipeline, and the oil outlet pipeline communicates with the throat of the carburetor body. In the design of the carburetor of the present invention, a rapid acceleration thickening device is added to force a certain amount of fuel to be sprayed into the mixing chamber during rapid acceleration, thereby ensuring the normal drivability of the outboard motor with a rapid fuel throttle.

Description

technical field [0001] The invention relates to a carburetor device, in particular to an outboard motor carburetor provided with a rapid acceleration thickening device. Background technique [0002] Generally, the outboard engine carburetor is not designed with a rapid acceleration and enrichment device. When the outboard engine is accelerating rapidly, because the supply of fuel lags behind the supply of air, the mixture will be too lean, resulting in poor acceleration and overspeed. Unsmooth, even flameout and other performance problems. Contents of the invention [0003] The purpose of the present invention is to provide a carburetor for outboard motor equipped with a rapid acceleration enrichment device, so as to overcome the problems in the prior art that the mixture gas is too lean, causing poor rapid acceleration, unsmooth overspeed, and even flameout. [0004] The present invention adopts the following technical scheme: an outboard motor carburetor equipped with a...
