What three primary components are necessary for the fundamental combustion reaction in an ICE?
What percentage of Earth's surrounding air serves as the oxidizer for conventional engines?
What happens immediately if an engine is run in an environment with zero ambient oxygen and no alternative oxidizer is supplied?
What is the primary engineering challenge when an ICE is supplied with pure oxygen instead of atmospheric air?
Which critical failure mode involves the incoming fuel/oxidizer mixture igniting before the spark plug fires due to excessive internal heat?
What is the term for the rapid, uncontrolled explosion within the cylinder that can severely damage pistons and connecting rods?
What component, present in atmospheric air, is removed when switching to pure oxygen, contributing to cooling inefficiency?
