Title:
AIR INLET PIPE OF STRATIFIED SCAVENGING TWO-STROKE ENGINE
Document Type and Number:
WIPO Patent Application WO/2022/236479
Kind Code:
A1
Abstract:
An air inlet pipe (1) of a stratified scavenging two-stroke engine, comprising air channels (5, 6), mixed gas channels (2, 3), and an air inlet pipe negative pressure hole (4). The air channels (5, 6), the mixed gas channels (2, 3), and the air inlet pipe negative pressure hole (4) are independent from each other; and the air inlet pipe negative pressure hole (4) is configured to penetrate through the air inlet pipe (1). The air inlet pipe (1) of the stratified scavenging two-stroke engine is provided with the air channels (5, 6) and the mixed gas channels (2, 3) that are independent from each other and do not interfere with each other, and thus can improve the air supply ratio of the stratified scavenging engine and improve the combustion state; moreover, different flowability is generated in the air inlet pipe (1), so that more two-stroke engine oil is attached to the wall of a cylinder.
