Stoichiometric point

Stoichiometric point

The stoichiometric point is a term commonly used to describe a particular fuel/air 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)
