W artykule przedstawiono wyniki analizy numerycznej procesu spalania metanu w silniku ZI ze zmiennym stopniem sprężania. Porównano parametry pracy silnika zasilanego ubogimi mieszankami metanu o λ = 1.4 oraz 1.8 dla siedmiu konfiguracji stopnia sprężania. Wyniki symulacji pokazały, że zastosowanie większego stopnia sprężania, przy współczynniku nadmiaru powietrza λ = 1.8, dało zbliżone parametry pracy silnika w porównaniu do przypadku zasilania mieszanką o λ = 1.4. Jednocześnie otrzymano ponad 25-krotnie mniejszą emisję tlenku azotu oraz zmniejszoną o 24% zawartość dwutlenku węgla w spalinach modelu silnika.

Results of numerical analysis of methane combustion in SI engine with variable compression ratio are presented in the paper. Work parameters of engine fuelled with methane lean mixtures of = 1.4 and 1.8 for seven configurations of compression ratio are compared. The results of carried out analysis proved that using higher compression ratio at air excess number λ = 1.8 caused that engine work parameters are similar to case of mixtures of = 1.4. Simultaneously, the emission of nitric oxide was decreased more than 25 times and the concentration of carbon dioxide in exhaust gases was 24% lower.
