Question

If oxygen increases in fuel what happens to fuel consumption

Answer 1

the conception is more efficient because the saturated or unsaturated compound burns more efficiently in presence of pure oxygen

Answer 2

Increasing the oxygen content to a reacting fuel-oxidizer mixture leads to faster burn rates and the ability to burn more fuel at the same stochiometry (oxygen to fuel ratio). These effects also have the potential to increase the thermal efficiency and specific power output of the diesel engine.
