Embodiment Construction

[0014] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0015] see figure 2 , a motorcycle carburetor with enhanced starting, comprising a carburetor body 8, an air volume hole 6, an idle nozzle and a transition nozzle 5 are opened on the carburetor body 8, and an idle oil well and a float are arranged in the carburetor body 8 Chamber 3, the idle oil well is composed of the idle oil well inner chamber 2 and the idle oil well outer chamber 4, the idle oil well inner chamber 2 is provided with an idle metering hole 1 at the bottom and a foam hole 7 at the upper part, which is characterized in that on the idle metering hole 1, oil There is no less than one starting thickening hole 9 drilled down in the plane.

[0016] see figure 2 , the working principle of the present invention is as follows:

[0017] (1) After the fuel flows into the carburetor, the pressure before and after the idle jet 1 is equal, that...

Abstract

The present invention relates to a motorcycle carburetor capable of raising starting performance. It includes carburetor self-body, on the carburetor self-body an air bleed jet, an idle discharge port and a transition port are cut, and the interior of the carburetor self-body has an idle fuel well and a float chamber, said idle fuel well is formed from its internal cavity and its external cavity, in the bottom portion of its internal cavity an idle metering jet is cut, and in its upper portion a foam hole is cut. It is characterized by that on the idle metering jet more than one starting concentration-increasing hole can be drilled under the fuel level, so that is can raise starting performance of engine, and can reduce discharge at the same tine of ensuring idle run.

Description

1. Technical field [0001] The invention relates to a motorcycle carburetor, in particular to the improvement of the motorcycle carburetor. 2. Background technology [0002] It is a common problem that motorcycles on the market are difficult to start. When the engine starts cold, the carburetor is required to provide a richer mixture. But when it enters the idling state after starting, in order to meet the requirements of the national emission standards, the mixed gas should not be too rich. This has caused the problem that the motorcycles on the market either have high emissions that do not meet the standard requirements, or are difficult to start. figure 1 It is a schematic diagram of the structure of the existing carburetor, and its working principle of the idle jet hole is as follows: [0003] (1) After the carburetor is filled with fuel, the pressure P before and after the idle jet 1 1 =P 2 , then the idle oil well cavity 2 pressure P K =P 0 ...
