Motorcycle carburetor

Abstract

The invention relates to a novel motorcycle carburetor which adopts an oil duct sleeve pipe shown as the figure 2, a neck opening 6 smaller than a main nozzle 2 is arranged in the sleeve pipe, a step 7 and a step 8 are expanded in a ladder shape, and a through hole 5 is arranged on the oil duct sleeve pipe and inclined to the direction of fuel oil 9. Air charged into an expanded limited air inlet hole 3 is increased and reversely impacts oil when passing through the through hole 5 on the oil duct sleeve pipe; the oil is easy to mix with the air by the impact, wherein the primarily mixed air can accelerate the flow speed when passing through the neck opening 6, and the quality of the mixed ratio is improved; when passing through the expanded step 7 and the step 8, the air reversely impacts the mixed air again, the mixing speed is improved, and the mixed ratio concentration in the first step is reduced; and when the mixed air in the first step is sprayed from the main nozzle 2, the mixed air is more fully mixed with the air 10 in the second step. After being installed and used, a motorcycle has less motorcycle body vibration and low power, air exhaust and exhaust pipe temperature, prolongs the service life of motorcycle power, reduces the oil consumption and strengthens the horsepower.

Description

technical field [0001] The invention relates to a two-wheel or three-wheel motorcycle carburetor technical background [0002] In a motorcycle carburetor, the mixed gas for the engine to work is carried out in two steps. The first step is to limit the air entering the air inlet, and after passing through the through hole on the wall of the oil passage casing, it is mixed with the oil at the bottom of the casing in the oil passage casing for the first time. In the second step, the primary mixed gas in the oil duct casing is sprayed out from the main nozzle and mixed with air in the mixing chamber. At present, the through holes of the oil passage casing in the carburetor are parallel air intake, because the oil is not subjected to the reverse impact of the air, resulting in insufficient primary mixing, which in turn affects the secondary mixing, resulting in insufficient combustion of power at the moment of compression explosion. It prolongs the combustion when the exhaust g...

Problems solved by technology

At present, the through holes of the oil passage casing in the carburetor are parallel air intake, because the oil is not subjected to the reverse impact of the air, resulting in insufficient primary mixing, which in turn affects the secondary mixing, resulting in insufficient combustion of power at the moment of compression explosion. Prolong the combustion of exhaust gas, cause high temperature of the engine and exhaust pipe, and accelerate the wear of the engine
