Abstract
Silindir cidarları üzerindeki yağ filmi motor çıkış hidrokarbon (HC) emisyonlarının ana kaynaklarından birisi olarak bilinmektedir. Bu çalışmada, benzin, LPG ve metan için yağ filmi içerine emilen/salınan yakıt miktarı için matematik bir model geliştirilmiştir. Yağ filmi tarafından emilen/salınan LPG ve metanın benzinden daha düşük seviyede olduğu görülmüştür. Bu farklılığın en önemli parametresi çözünürlükle ilgili olan Henry sabiti olduğu tespit edilmiştir. Düşük motor devirlerinde yağ filmi yakıt buharı etkileşimine daha uzun süre tanındığı için emilen/salınan HC miktarları artmıştır. Artan sıkıştırma oranı ve giriş basıncı ile birlikte emilen/salınan HC miktarları artmıştır.
