Abstract
SENSOR DE GáS, CONTROLADOR DA RELAçãO AR-COMBUSTìVEL, E APARELHO DE TRANSPORTE. Um sensor de gás do tipo resistência que inclui uma seção de detecção de gás incluindo uma camada semi-condutora de óxido. A camada semi-condutora de óxido inclui íons de cério e íons de zircónio. Uma quantidade da substância de íons de zircónio em relação à soma das quantidades de substância de íons de cério e íons de zircónio contida na camada semi-condutora de óxido não é inferior a 45% e não é maior do que 60%, e a camada semi-condutora de óxido tem uma fase cristalina contendo 80% em volume ou mais de cristais cúbicos.
