Abstract

In this paper are presented some results of research into gaseous emissions from a two-stroke engine. These engines require a particular fuel consisting of a mixture of petrol and lubricating oil. In the research, a comparison was made between fuel mixtures containing mineral and synthetic base-stock lubricants, in order to check the chemical differences between exhaust emissions from the same motor run under the same conditions. This comparison was made because synthetic lubricants based on organic carboxylic esters, when compared to mineral ones, have same peculiar properties: a smaller combustion residue, better lubricating ability and better thermal stability. There are therefore good reasons to suppose that the lubricant fraction of fuel mixtures, after combustion, may cause gaseous emissions whose composition may vary according to the lubricant used.
