Abstract
Environmental awareness is increasing day by day. People want to use environmental friendly products. Vehicles have become one of the essential tools of people. The use of less polluting vehicles has also been made mandatory by countries. In internal combustion engines, the highest level of air pollutant exhaust gas emissions occur while the engine is running in cold start conditions. In this study, a catalytic converter was examined with a commercial software using a one-dimensional model during cold start. The effects of parameters such as grid number, grid shape factor, number of channels are examined. As a result, it has been determined that the onedimensional model can be accepted in accordance with the literature. It has also been shown that the number of channels in the catalytic converter are important

Abstract
Çevre duyarlılığı her
geçen gün daha da artmaktadır. İnsanlar çevreye dost ürünler kullanmak
istemektedirler. Taşıtlar ise insanların vazgeçilmez araçlarından birisi haline
gelmiştir. Daha az hava kirleten taşıtların kullanılması da ülkeler tarafından
zorunlu hale getirilmiştir. İçten yanmalı motorlarda en fazla hava kirletici
egzoz gazı salımı motorun soğuk olarak çalıştığı sürede olmaktadır. Bu
çalışmada soğuk çalışma sırasında bir katalitik konvertörün tek boyutlu model
kullanılarak ticari bir yazılım ile incelenmesi yapılmıştır. Grid sayısı, grid
şekil faktörü, kanal sayısı gibi parametrelerin etkileri incelenmiştir. Sonuç
olarak tek boyutlu modelin literatür ile uyumlu olarak kabul edilebilir olduğu
belirlenmiştir. Katalitik konvertör içindeki kanal sayısının da önemli olduğu
gösterilmiştir.
