The physical properties of physic nut oil and performance of diesel engine using physic nut oil as a fuel

Abstract

This paper presents the physical properties of physic nut oil and physic nut oil blended with
diesel fuel. The performance test of diesel engine running with these oils also has been tested. The
physical properties are specific gravity, cetane index, heating value, flash point and viscosity. The
performance, using one cylinder diesel engine 411 C.C., has been tested within torque, break power,
specific fuel consumption and black smoke in exhaust gas. The results show that physical properties
of physics nuts oil and their blend with diesel similar to diesel oil. Furthermore the performance of the
engine, which is run by that oil, are in good conditions. When the physic nut oil and physic nut oil
blended with diesel oil was used as a fuel, the engine gave slightly higher torque and power
compared with the standard diesel. The specific fuel consumption of physic nut oil and physic nut oil
blended with diesel fuel slightly higher compared with the standard diesel. The black smoke from the
exhaust gas is in the environment laws.
