Differences in engine oil degradation in spark-ignition and compression-ignition engine

Popis výsledku v původním jazyce

This paper deals with differences in engine oil degradation in spark-ignition (SI) engine and compression-ignition (CI) engine. Three important physical-mechanical behaviours were observed -- dynamic viscosity, kinematic viscosity, and shear stress. These behaviours of lubricant may influence reliability of entire engine. It must be monitored engine oil condition in suitable intervals. Article describes these issues for two engine oils taken from two different passenger cars with SI engine and with CI engine. The experiments have been done using digital rotary rheometer Anton Paar DV-3P with use of standard TR8 spindle and special adapter for a small amount of sample. Service interval of change oil has been set to 15,000 km and samples of used engine oils have been taken after 1,500 km from both engines. All samples of used engine oils have been compared with new engine oils same specification -- it is the best method to degradation detection. The measured values of dynamic viscosity,
