What is the function of the EGR valve in a vehicle's exhaust system?
The EGR valve reduces the production of NOx by diluting the intake air with exhaust gases.
The EGR valve increases the temperature of the flame and the oxygen content in the burned gases.
The EGR valve is activated by the throttle and controlled by the oxygen sensor.
The EGR valve is necessary for the engine to function properly at low speeds and during initial heating.

A função da válvula EGR (Exhaust Gas Recirculation) no sistema de escape de um veículo é reduzir a produção de NOx (óxidos de nitrogênio) diluindo o ar de admissão com gases de escape. Portanto, a alternativa correta é: "A válvula EGR reduz a produção de NOx diluindo o ar de admissão com gases de escape."
