Emission and Lubrication Performance of Hazelnut Oil as A Lubricant

Abstract

The aim of this study is to search the tribological and emission performances of hazelnut
oil as a lubricant in one cylinder two-stroke gasoline engine and simulation-testing
machine. The tribological and emission performances of mineral oil and hazelnut oil as
lubricant were compared. In the experiments, simulation-testing machine and one
cylinder two-stroke gasoline engine were used to determine the tribological performance
of these two lubricants. The wears on the surfaces of cylinder were analyzed to examine
the lubricant performances. In addition to lubrication performance, exhaust emissions of
the lubricants were also measured. To observe the effects of different kinds of cylinder
surface materials, TiN, CrN and gray cast iron coated cylinder surfaces were used in
simulation testing machine. The wear as well as the soot formation on the cylinder
surfaces increased when hazelnut oil was used as the engine lubricant. However, hazelnut
oil exhibited good lubrication properties in simulation testing machine. When hazelnut
oil was used, CO and HC emissions increased while CO2 emission decreased.
