Emission Control of Four-Stroke Motorcycle Engine
SAE Technical Paper Series, 1995<div class="htmlview paragraph">Experimental studies of the intake-generated charge motion (swirl and tumble) and engine combustion were conducted in a 125 cc four-stroke motorcycle engine. In this work, a Variable Inlet Port (VIP) was designed to generate various levels of charge motion in different operation conditions. The static flow test and
