Abstract

The invention discloses a two-stroke stratified scavenging engine. The two-stroke stratified scavenging engine mainly comprises an air scavenging part and a mixed gas scavenging part. The air scavenging part mainly comprises an air storage cavity (10) and an air scavenging passage (15), wherein the air storage cavity (10) and the air scavenging passage (15) are arranged in one side of an engine body (4). Two ends of the air scavenging passage (15) are communicated with an air scavenging port (16) and the air storage cavity (10) in the inner wall of one side of a cylinder body (2). The mixed gas scavenging part mainly comprises mixed gas scavenging passages (17 and 19) arranged in the inner wall of the cylinder body, and the mixed gas scavenging passages are of closed cavity structures. The two-stroke stratified scavenging engine is provided with independent air scavenging passages, short-circuit loss of fresh mixed gas is greatly reduced, hazard waste emission of the engine is reduced, and the two-stroke stratified scavenging engine is energy saving and cost reducing.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a two-stroke stratified scavenging engine. Background technique [0002] High-speed small-displacement two-stroke engines have the advantages of high mechanical efficiency, high specific power and low cost, and occupy a huge market space in the fields of agriculture, forestry, construction, garden plant protection, sports and entertainment. However, the two-stroke gasoline engine is affected by factors such as poor economy and emission performance, especially HC+NO x And CO emissions, causing serious environmental pollution, its development has been subject to certain restrictions. In recent years, under the dual pressure of energy and environmental issues, governments of various countries have introduced increasingly stringent emission regulations. In order to reduce the harmful emissions of two-stroke engines and make them comply with emission regulations, it is of great soci...
