In general, it’s actually quite simple: If you want something to burn, you’ll need oxygen – otherwise the fire will extinguish itself in no time. The same applies to a combustion engine. The only difference is that a highly complex interplay of different, precisely harmonised components is required in order to optimally supply the engine with the air required for combustion.
