The production of exhaust gas emissions in combustion engines has been the subject of many studies all over the world, including exhaust gas emissions produced in the combustion of biofuels. The studies have mainly focused on the production of exhaust gas emissions from using various fuel mixtures in various types of engines. The effect of biofuels on the exhaust gas emissions of two-stroke spark-ignition engines has been studied less. The reason for that is the fact that the two-stroke engines in widespread use have no engine lubrication system and the engine is lubricated by lubricant mixed into the fuel. For example, when using bioethanol, the addition of lubricant to the fuel is complicated because fuel oils generally stratify out of bioethanol. The goal of the article was to investigate the effect of bioethanol fuel blends on the exhaust gas emissions on a two-stroke engine. Particularly, the effect of bioethanol fuel blends on the compounds contained in the exhaust gas emissions of a two-stroke engine was studied. The weight shares of the following compounds were studied: CO, CH, NO2, C3H4O, C4H6, HCHO. The test fuels were petrol with the octane number of 95, medical bioethanol 96.3% (water content 3.7%) and low-grade bioethanol (LGBE80, water content 20%). The additives added to the fuels were Addinol MZ408 two-stroke engine oil, hot-pressed rape oil and refined rape oil. The test data indicated that the use of biofuels in two-stroke engines produces higher shares of several toxic compounds (HCHO) than the use of petrol.
