Experiences in Lubrication of non-Natural Gas Fuelled Stationary Engines

Abstract

In Europe, a huge number of generators for electric power, powered by those stationary engines are becoming increasingly popular in regions where these renewable fuel sources are available. Nevertheless, the continuously pending quality, caloric value and the harmful constituents of the non-natural gas fuel are placing greater demands on the engine operation and its lubrication system. These phenomena drew our attention to the lubrication issues of the stationary gas engines. These gas engines can expose the engine oil to a severe chemical impact of dirt fuel impurities, acidity, nitration and oxidation conditions and can be very sensitive to additive chemistry and oil composition. In this paper we provide a representative case study and we’ll report about our experiences on lubrication of gas engines, fuelled with wood gas.
