Abstract
In a variety of liquid and air cooled, gasoline 2-Cycle Engines, testing has suggested that performance of can be significantly influenced by the components used in 2-Cycle lubricants. A blend of anti-scuff, deposit control, and combustion modification additives in combination with carefully selected base oils is needed to produce an optimum 2-Cycle lubricant. Research has shown that Bright Stock, while being an excellent anti-scuff agent increases engine deposits and exhaust smoke. Use of polybutene (polyisobutylene) polymers or synthetic anti-scuff agents in place of Bright Stock has been found to be an effective means of controlling smoke while maintaining good anti-scuff performance. Use of polybutenes, however, may cause the formation of sticky deposits. Development of a synthetic, low smoke, high performance 2-Cycle Oil is reviewed. Incorporation of a combustion modifier in 2-Cycle Oils is also reviewed.
