The single-cylinder, four-stroke, overhead valve Biggs & Stratton engine was studied for the possible toxinity with the view of solving the environmental pollution problem related to the internal combustion engine emissions. As an assessment of toxicity, the data recorded (INFRACAR 5M3T) in the exhaust gases of the power unit NOx, CO and CH was used. Evaluation of the toxicity of the engine running under load was carried out by testing (CARTEC LPS 2510 dynamometer) an engine-equipped vehicle of simplified design (buggy). It was shown that the presence of CO, CH and NOx in the exhaust gases is affected not only by the presence of alcohol in gasoline, but also by the crankshaft speed. It was found that the proportion of CH in the exhaust gases of the power unit running on gasoline is lower than the maximum allowable content of hydrocarbons in the exhaust gases of gasoline engines not equipped with a neutralization system. According to the data obtained from bench tests, it follows that the proportion of CH in the exhaust gases of a gasoline-fueled engine is on average 48% higher than in the exhaust gases of an engine fed with a gasoline-alcohol mixture. It was shown that a significant increase in power at the wheel does not lead to a sharp increase in the CH content in the exhaust gases. The proportion of CH in the exhaust gases in the obtained speed range is a constant value.
