Performance Test Methods for Two-Stroke Cycle Engine Lubricants Including Lean Fuel-Oil Ratio Conditions 790078
Development of 2-stroke cycle gasoline engines towards higher specific outputs and environmental aspects have resulted in more stringent lubricating oil requirements. A classification system is being generated by SAE/ASTM/API in cooperation with CEC to facilitate selection of suitable oils with different performance levels depending on their application.
Standardized CEC Test Methods and European in-house tests used for 2stroke oil development are described and discussed. Special oils for use at lean fuel : oil ratios and biodegradeable lubricants have been developed. Typical bench and field test results obtained with modern formulation concepts and reference oils are presented.
