The Difference Between the Physical Properties of Petrol and Alkylate Petrol and Impact on the Exhaust Gas of a Two-Stroke Engine

Abstract

The use of a two-stroke engine as the power unit on different hand tools is a widespread tendency. In case of the particular hand tools, it is crucial to keep the exhaust gas emission of the engine as low as possible. To reduce the exhaust gas emission of a two-stroke engine, alkylate petrol has been worked out. According to manufacturer's data, using alkylate petrol in a two-stroke engine improves the combustion of the air-fuel mixture, thus, the proportion of dangerous compounds in the engine exhaust gas also decreases. However, it is not exactly clear how much the proportion of dangerous compounds, e.g. carbon monoxide, in the exhaust gas decreases. The aim of the given article is to study the exhaust gas emission during the combustion of alkylate petrol and outline the proportion of dangerous compounds at different loads of a two-stroke engine. The results indicate that when alkylate petrol is used, the proportion of carbon monoxide in the exhaust gas increases.
