The stoichiometric point is the air to fuel ratio in a combustion engine. The stoichiometric air-fuel ratio for petrol (gasoline) is 14.7 to 1 by weight.

Related concepts include:

  • Air fuel ratio
  • Stoichiometry
  • E85 in standard engines
  • Lean burn
  • Combustion
  • Gasoline direct injection (which can use ultra lean modes - many times the stoichiometirc ratio)
  • Catalytic converters (which are at peak efficient when the engine runs slightly above the stoichiometirc point)
