Summary:

This paper describes a stratified scavenging system of twostroke cycle engine, developed to reduce HC (hydrocarbon) emission caused by shortcircuiting mixture at scavenging process. The fact, the maximum shortcircuiting of fuelair mixture occurs at the timing soon after the scavenging port open, led us to the idea of stratified scavenging, that is, first stage of scavenging by air without fuel, then second stage by airfuel mixture. The stratified scavenging system consists of long passages from crankcase to scavenging ports, and the supplemental air intake system directly to the scavenging portrait The newly developed stratified scavenging twostroke cycle engine cuts HC emission to about 1/4 of conventional twostroke, and can meet the CARB Tier 2 emission regulation
