Özet

Most of the studies conducted on reverse-uniflow type scavenging method developed in order to remove the deficiencies of the Schnürle type two stroke engines are related with developing flow processes and determining engine performance. Until today, no studies related with combustion characteristics of these engines were published. In this study, a real time combustion analysis system was experimentally applied to a two stroke reverse-uniflow engine for online analysis of the combustion values and gathering data. The experiments were conducted under full load, 1800 1/min and by changing ignition timing before TDC between 16-24 ºCA by steps of 4 units each and accordingly cylinder pressure, mass fraction burned profile, heat release rate and indicated efficiency changes were examined. The analysis of this data allows the determination of ideal combustion phase providing maximum indicated efficiency. The performed tests show that most ideal combustion phase was obtained by adjusting the ignition timing to 20 ºCA before TDC. © 2017 TIBTD Printed in Turkey.
