Oxygen Engine

Oxygen Engine :

🔹 1. Rocketry / Aerospace

• An oxygen engine often refers to a rocket engine that uses liquid oxygen (LOX) as an oxidizer.
• Common fuel pairings include:
  • LOX + RP-1 (kerosene) → used in rockets like the Falcon 9 (SpaceX) or Saturn V.
  • LOX + liquid hydrogen (LH2) → used in the Space Shuttle Main Engines (SSME).
• Oxygen itself doesn’t burn, but it allows fuel to combust in the vacuum of space where there’s no atmospheric oxygen.

🔹 2. Internal Combustion Engine Concept

• In theory, an oxygen engine could mean an ICE that runs with compressed oxygen instead of drawing air (which is only ~21% oxygen).
• This could:
  • Increase combustion efficiency.
  • Boost horsepower since oxygen-rich mixtures burn more powerfully.
  • But: It’s dangerous — pure oxygen can cause explosions and extreme wear due to higher combustion temps.

🔹 3. Clean / Alternative Energy

• Some experimental designs use oxygen in fuel cells (like hydrogen-oxygen fuel cells).
• In these systems:
  • Hydrogen fuel reacts with oxygen.
  • Produces electricity + water as a byproduct.
• This is the basis for many proposed green energy propulsion systems.

🔹 4. Biological / Metaphorical Engines

• Sometimes "oxygen engine" is used metaphorically to describe respiration in living organisms: the mitochondria in cells use oxygen to generate ATP (energy).
