Abstract

The invention discloses an air filter choke valve device of a gasoline engine. According to the device, a choke valve plate is inserted into an air filter body; due to the fact that positioning through holes matched with a telescopic elastic positioning device are formed in the choke valve plate, the telescopic elastic positioning device is clamped into the different positioning through holes to position the choke valve when the choke valve plate is controlled to move, further, the choke valve blocks air inlets of the air filter body at different degrees, and air inflow of the air filter body is accurately and conveniently controlled. In addition, an oil bubble pump and a carburetor are separated, the oil bubble pump is installed on the top of the air filter body, inconvenience caused by integrated operation of the oil bubble pump and the carburetor is avoided, and oil mass of the oil bubble pump can be conveniently observed.

Description

technical field [0001] The invention relates to a choke device, in particular to a choke device suitable for an air filter of a gasoline engine. Background technique [0002] The air filter on the gasoline engine is usually used together with the carburetor. After the air enters the air filter through the choke valve on the air filter, it enters the carburetor after being filtered by the air filter. The carburetor combines the filtered air with the carburetor. A certain amount of gasoline is mixed evenly and then supplied to the engine to run normally. Among them, the mixing ratio of fuel and air in the carburetor is very important. When there is too much air and too little fuel, the engine will run in a "lean fuel" state, which will stop the engine or even damage the engine; if there is too little air and too much fuel , the engine will run in a "rich oil" state, the carburetor will overflow oil or the engine will produce a lot of black smoke, etc., and the engine will be ...
