EN Research on machines is often conducted using the scale effect. By studying the effects in low-power machines, it is sometimes possible to transfer these effects to high-power machines, taking into account the scale factor. The aim of the article is to determine the impact of the engine displacement of internal combustion engines driving positive pressure fans on the concentrations of carbon dioxide (CO2), Carbon monoxide (CO), hydrocarbons (HC), (nitrogen oxides) NOx, and particulate matter (PM10) in exhaust gases. The article examined four of the most popular internal combustion engines used for driving positive pressure fans, with displacements ranging from 163 cm3 to 270 cm3. When the device operates at full power (which is the most common operating condition for this device), the following mean concentration ranges were demonstrated: CO2 2.22–6.98 %, CO 1.28–3.57 %, HC 46.13–135.56 ppm, NOx 68.68–197.50 %, PM10 0.42–0.93 mg/m3. For CO2, CO, and PM10, the slope of the trend line being close to zero degrees (α≈0°) indicates that the function is constant, allowing the conclusion that the scale effect can be applied to the studied concentrations depending on the change in engine displacement. However, for HC (α=31.6°) and NOx (α=3.1°), such inference may be incorrect as y is dependent on x.
