Experimental Research of Labyrinth Air-Head Scavenging Project - For Reducing Idling Pollutants from Two-Stroke Motorcycle 911303
The key point of reducing idling pollutants from two-stroke engine is to improve gas exchanging quality. This paper proposed a new construction of air-head scavenging project- labyrinth air-head scavenging project. Test results prove that this project together with delaying ignition timing, increasing idling delivery ratio and high-energy ignition can make the idling pollutants of 1E46FM engine reducing from HC> 8000ppm to 5800ppm and CO from 4.8% to <2.0%.
