Abstract
The small two-stroke gasoline engine has recently become very popular owing to improvements in design and performance, and because of its general cheapness and simplicity of construction. Most of these engines are lubricated by the ‘Petroil’ system, that is, the oil and gasoline are mixed together before they are put into the fuel tank. This system, together with the characteristic design features of the engine, leads to various problems, the commonest of which are sparking plug fouling, exhaust port blocking, piston seizure, bearing corrosion, and general piston deposits. Various engine tests were used to study these problems, and it was found that their overall solution demanded conflicting properties of the lubricating oil. By a suitable compromise, however, it is possible to formulate an oil which gives satisfactory results in all aspects of performance.Keywords
