Natural Language Definition
EN
An ignitor is an assembly designed to initiate the ignition of a combustible fuel-air mixture by generating a spark, arc, or other ignition source that supplies the activation energy needed to trigger self-sustaining combustion.
PT-BR
Um ignitor é um conjunto projetado para iniciar a ignição de uma mistura combustível de combustível-ar, gerando uma faísca, arco elétrico ou outra fonte de ignição que fornece a energia de ativação necessária para desencadear uma combustão autossustentável.

Process Participation Signature ⟨I, O, T⟩
Inputs (I)
CombustibleMixture
— fuel-air mixture at ignitable concentration
IgnitionEnergy
— electrical, thermal, or pyrotechnic energy for spark generation
Outputs (O)
Flame
— sustained flame that initiates combustion process
Transformation (T)
generation of a spark or thermal source that initiates self-sustaining combustion in a combustible mixture
The ignitor converts a supplied energy form into the localised activation energy required to start combustion, which then propagates independently.

Axiom Mode Decision

— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
