Assessing the High-Temperature Deposit Formation of Paraffinic and Naphthenic Oil Blends Using the Oil Chute Method

Due to the demand for higher efficiency, gas engine designs are changing in that oils exposed thermal stress and face challenges regarding prevention of deposits. In this work, “oil chute” laboratory test was used study high-temperature deposit-formation tendency various paraffinic naphthenic base oil blends. The chute is a setup circulates through two different temperature zones, hot zone being heated metal triggers deposit formation. addition, thermo-oxidative stability blends investigated using an artificial alteration method. results showed have capability substantially reducing However, they tend degrade faster under stress. Therefore, finding right balance between components will allow formulation provide properties cope with levels subjected modern engines.
