Abstract

The utility model provides a secondary atomizer for a carburetor of a gasoline engine. A perforated baffle plate or a meshed screen is fixedly arranged in a central through hole of a shim between a gas cylinder and a carburetor of a gasoline engine to improve the atomization effect of the carburetor of the gasoline engine to gasoline. The combustion of the gasoline which is atomized for the second time is complete, and degree of pollution of the discharged waste gas to the environment is little. Compared with the existing gasoline engine, the fuel oil of the utility model can be saved by 10 %to 30%.

Description

The secondary-atomizing device of gasoline engine carburetor

The utility model belongs to the atomising device field, relates in particular to the secondary-atomizing device of gasoline engine carburetor.

In the prior art, petrol engine is that devices such as the small venturi by Carburetor, middle trunnion, big trunnion carry out to the atomizing of gasoline.Owing to be subjected to the restriction of atomization space or the structural defective of atomising device itself, the atomizing that is easy to generate gasoline is insufficient, make and cause the atomization gas incomplete combustion, and then the waste gas that petrol engine is discharged exceeds standard by elaioleucite skewness in cylinder.This has not only reduced the utilization ratio to gasoline, and institute's exhaust gas discharged pollutes environment.

The purpose of this utility model is: provide a kind of secondary-atomizing device of gasoline engine carburetor, to improve the atomizing effect of gasoline engine carburetor to gasoline.

For achieving the above object, the technological scheme of the secondary-atomizing device of the utility model gasoline engine carburetor is to be provided with pad between Carburetor and cylinder, in the through hole at pad center, be installed with a porous catch, the below of porous catch and pad central through bore contacting point has the half-round cross hole that a radius is about the 2-8 millimeter on the porous catch.

The further technological scheme of secondary-atomizing device of gasoline engine carburetor described in the utility model is: top 1/3 to 1/2 part of porous catch approximately is provided with 3-300 hole, and each hole is uniform at the first half; Bottom 1/2 to 2/3 part approximately is provided with 3-800 hole, and each hole is uniform in Lower Half.

The secondary-atomizing device of gasoline engine carburetor described in the utility model further technological scheme is: the porous catch can be an orifice plate, also can be hole pattern.

Advantage of the present utility model is: the gasoline combustion through secondary-atomizing is abundant, and institute's exhaust gas discharged pollution on the environment degree is smaller, saves fuel oil.

Below in conjunction with accompanying drawing the utility model is done explanation in further detail:

Fig. 1 is the floor map of a kind of form of the utility model;

Fig. 2 is the floor map of the another kind of form of the utility model;

At the schematic representation shown in Fig. 1,2 is the pad 1 of gasoline engine carburetor and cylinder joint, and 2 are fixed with a porous catch 3 in the through hole in the middle of pad 1.The below of the cylindrical of porous catch 3 and pad central through bore contacting point as the idling oil inlet hole, has the through hole 4 that a radius is about the semicircle of 2-8 millimeter on the porous catch.Top 1/3 to 1/2 part of porous catch 3 approximately is provided with 3-300 hole, and each hole is uniform at the first half; Bottom 1/2 to 2/3 part approximately is provided with 3-800 hole, and each hole is uniform in Lower Half.Porous catch 3 can be an orifice plate, also can be hole pattern.

Claims

1, a kind of secondary-atomizing device of gasoline engine carburetor, it is provided in a side of the pad between Carburetor and the cylinder, it is characterized in that: in the through hole at pad center, be installed with a porous catch, the below of porous catch and pad central through bore contacting point has the half-round cross hole that a radius is about the 2-8 millimeter on the porous catch.

2, the secondary-atomizing device of gasoline engine carburetor according to claim 1 is characterized in that: top 1/3 to 1/2 part of porous catch approximately is provided with 3-300 hole, and each hole is uniform at the first half; Bottom 1/2 to 2/3 part approximately is provided with 3-800 hole, and each hole is uniform in Lower Half.

3, the secondary-atomizing device of gasoline engine carburetor according to claim 1 is characterized in that: the porous catch can be an orifice plate, also can be hole pattern.
