Abstract

The utility model relates to a carburettor for internal-combustion engines, particularly a carburetor for motorcycles and light vehicles. The utility model is formed by assembling an empty filter assembly and a carburetor assembly. A ring which is connected to a pipe inner wall is arranged on the pipe inner wall of the main fuel spraying nozzle of the carburetor. The ratio of the inner diameter of the ring and the pipe inner diameter of the main fuel spraying nozzle is 0.9414: 1. When the utility model is used, fuel consumption is small, and fuel can be fully combusted, which is favorable to the reduction of air pollution, and the fuel is saved.

Description

Carburetor

The utility model relates to a kind of Carburetor of internal-combustion engine, the Carburetor of particularly a kind of motor, light cavalry's car.

The main oil injecting nozzle of the vaporizer of the Carburetor of existing motor, light cavalry's car is unreasonable because of structure, and therefore, fuel consumption is bigger, does not often reach designing requirement, and oil can not fully burn, not only contaminated air, and waste fuel.

The purpose of this utility model is: a kind of technological scheme of Carburetor is provided, and this Carburetor fuel consumption is less, and oil can fully burn, favourable minimizing atmospheric pollution, fuel saving.

The technical solution of the utility model is: Carburetor is formed by connecting by the assembling of empty filter assembly and carburetor ASSY has on the inner tube wall of main oil injecting nozzle of vaporizer one to be linked as one ring with inner tube wall.The ratio of the internal diameter of the ring that is connected as a single entity with the inner tube wall of main oil injecting nozzle and the bore of main oil injecting nozzle is 0.9414: 1.The ring that is connected as a single entity with the inner tube wall of main oil injecting nozzle and the mouth of pipe distance of main oil injecting nozzle are 2.4-2.6mm; The internal diameter of the ring that is connected as a single entity with the inner tube wall of main oil injecting nozzle is 2.40-2.42mm, and the bore of main oil injecting nozzle is 2.56mm; The transverse cross-sectional profile of the ring that is connected as a single entity with the inner tube wall of main oil injecting nozzle be "

Shape.

Major advantage of the present utility model is: fuel consumption is little, this Carburetor is contained on happy 250 motorcycles tries out, per 100 kilometers oil consumption 2.3L when unloaded, load-carrying 250Kg, per 100 kilometers oil consumption 2.5L, do not use this Carburetor before, per 100 kilometers oil-consuming standards are 3-3.5L.Its fuel-economizing reason is that this Carburetor can make the fully mixed in proportion vaporization of oil and air, thereby sufficient combustion, reduces atmospheric pollution, fuel saving.

Below in conjunction with drawings and Examples the utility model is further specified:
