Abstract:
Because of their advantages, natural gas engines are very popular choice today, especially for use in commercial and public vehicles (commercial vehicles, trucks, buses, trains). Lubricant is an important element of the gas engine, as well as of any other type of internal combustion engine. The lubricant has multifunctional role. From reducing friction between surfaces, through transferring heat, neutralizing acids, removing hard carbon deposits and maintaining desired viscosity. In order to fulfill effective, long run and economical functioning of the engine, appropriate lubricant must be selected and used. Also, it has to be compliant with the fuel gas quality, exploitation conditions, environmental requirements et cetera. The purpose of this paper is to present the important properties of lubricating oils for automotive internal combustion engines powered by natural gas.
