Valuating the impact of biodiesel B10, B20 on lubricating oil in a commonrail diesel engine

Abstract

Biodiesel typically has a higher boiling point, viscosity, density, and surface tension compared to traditional diesel. This can result in larger fuel droplets and potentially increased penetration into the engine crankcase. This article presents experimental findings on the impact of using biodiesel blends B10 and B20 (with B100 made from palm oil) on key lubricating oil properties in a D4CB 2.5TCI-A diesel engine equipped with a CommonRail fuel injection system installed in a Hyundai Starex vehicle. The evaluation is based on comparing lubricating oil properties when using different fuels: diesel (B0), biodiesel B10, and biodiesel B20 over a 3000 km driving cycle. Results indicate that the effects of B10 and B20 on lubricating oil properties are similar to those of conventional diesel B0.
