A numerical and experimental study was carried out on oxygen enriched intake in an spark ignited (SI) engine. The study aims at validation of Wiebe function for oxygen enriched intake. This computational study was carried out at full load conditions at four engine speeds (2500, 3000, 3500 and 4000 rpm) for different blends of oxygen enriched gasoline (4%, 8% and 12% by mass of oxygen) in AVL BOOST, a one dimension engine analysis software. The computational and experimental results complement each other validating the use of AVL Boost for oxygen enriched intake. HC and CO emissions decreased drastically with increasing concentration of oxygen. However, there was abrupt increase in concentration of NOx emissions.

Obliczeniowe i eksperymentalne badania przeprowadzono na silniku z zapłonem iskrowym (SI) wzbogaconym przy wlocie w tlen. Badanie miało na celu walidację funkcji Wiebe, która służy do poboru tlenu. Obliczenia przeprowadzono w warunkach pełnego obciążenia na czterech prędkościach obrotowych (2500, 3000, 3500 i 4000 rpm) dla różnych mieszanek benzynywzbogaconej w tlen (4%, 8% i 12% w stosunku do masy tlenu) w AVL Boost, oprogramowaniu, które analizuje jeden wymiar silnika. Obliczeniowe i doświadczalne wyniki uzupełniają się wzajemnie i sprawdzają wykorzystanie AVL Boost, przy poborze tlenu do silnika. Emisja HC i CO spadła drastycznie wraz ze wzrostem stężenia tlenu. Nie zauważono jednak nagłej zmiany stężenia emisji NOx.
