Two-stroke stratified scavenging gasoline engine

Abstract

The invention discloses a two-stroke stratified scavenging gasoline engine which comprises a cylinder body, a crankcase, an air inlet pipe and a carburetor, wherein an air inlet, an exhaust opening, secondary scavenging channels and an air storage chamber are arranged on the cylinder body; the secondary scavenging channels are connected with the air storage chamber; a scavenging opening is formed above each secondary scavenging channel in the air storage chamber; two main scavenging channels are respectively connected to two sides of the cylinder body; an air channel is arranged above the air inlet and is directly connected with an air flowing groove in each main scavenging channel; each air channel is connected with the air storage chamber; the two secondary scavenging channels are symmetric about the center of the cylinder body. Due to the adoption of a scavenging mode of placing air at the front side and placing the mixed gas at the rear side, the contents of harmful components in tail gas can be effectively reduced, the discharge of pollutants is greatly improved, the fuel consumption rate of the engine is effectively reduced, and the fuel economy is improved.

Description

Technical field [0001] The present invention involves the field of engine technology, especially a two -stroke -stroke -of -the -moving gasoline engine. Background technique [0002] At present, the extensive use of the two -junction gasoline engine has a shortage of US -China. It consumes high fuel, especially the severe discharge pollution, and it is no longer in line with relevant laws and regulations.The layered sweeping two -stroke gasoline engine has the characteristics of low emissions and low fuel consumption, which is favored by consumers, but its intake system, especially the structure of the carburetor, is relatively complicated, poor reliability, and the price of the whole machine is high.Disadvantages; an existing technology urgently requires a simple structure and economical and practical two -way stratified gasoline engine. Invention content [0003] Existing technology cannot meet people's needs. In order to make up for the lack of existing technologies, the inve...

Problems solved by technology

[0002]The currently widely used two-stroke gasoline engine has a fly in the ointment. It consumes high fuel, especially the emission pollution is serious, which no longer meets the relevant laws and regulations.

Stratified scavenging two-stroke gasoline engine has the characteristics of low emission and low fuel consumption, and is favored by consumers. However, its air intake system, especially the carburetor, has a complicated structure, poor reliability, and high price of the whole machine. Disadvantages: In the prior art, there is an urgent need for a simple in structure, economical and practical two-stroke stratified scavenging gasoline engine
