Problems solved by technology

When the engine is working under non-full load conditions, the speed of the engine decreases, and the negative pressure of the inhaled mixture decreases accordingly, and the cross-sectional area of ​​the venturi tube 10 does not change. The airflow velocity of the airflow slows down, and the slow decompression of the airflow velocity makes the atomization effect of the mixture gas unsatisfactory. Therefore, when the engine is working at idle speed and transition point, the atomization effect of the mixture gas is not as good as when the engine is fully loaded. The atomization effect is good, which leads to an increase in the emission value of the engine under non-full load conditions, which cannot meet the requirements of environmental protection

Abstract

The invention discloses a main oil system structure and a carburetor having the same. The carburetor comprises a carburetor body and a main oil system structure; the main oil system structure comprises a main oil well, a main spray pipe, a main measuring hole and an atomization adjusting mechanism, wherein the main oil well is arranged in the carburetor body, the main spray pipe and the main measuring hole are installed in the main oil well; the atomization adjusting mechanism is arranged in the carburetor body relating to the main spray pipe and a choke hole of the carburetor body, the atomization adjusting mechanism is connected with the speed regulating mechanism of an engine to be synchronous with the working condition of the engine, and the atomization adjusting mechanism improves the atomization performance of the carburetor through simultaneously changing the sectional area of the venture of the carburetor and the fuel spraying quantity of the main spray pipe, so as to enable the engine to keep good atomization effect under various working conditions.

Description

technical field [0001] The invention relates to a carburetor, in particular to a main oil system structure capable of maintaining a good atomization effect of the engine under different working conditions and improving the atomization performance of the carburetor and a carburetor with the structure. oiler. Background technique [0002] Due to its wide range of uses, complete functions, economical convenience and other characteristics, general-purpose gasoline engine products are becoming more and more popular among users, and their market capacity is also expanding. Especially in the agricultural field, they have been widely used, and the global market demand is huge. The market is in the ascendant and the prospect is very bright. With the widespread use of general-purpose gasoline engines around the world, more and more people pay more and more attention to the resulting engine pollutant emissions. In recent years, with the implementation of Euro Ⅲ emission standards and...
