Abstract

Método e dispositivo para estimar o fluxo de ar de admissão em um motor a combustão interna. é descrito um método para estimar o fluxo de entrada de um motor (1) a combustão interna, dotado de um sistema de admissão de ar (2), sendo que dito sistema compreende meios de válvula (6) para controlar o dito fluxo de ar de admissão, caracterizado pelo fato de que este compreende as fases de implementar um primeiro e um segundo algoritmos apropriados para se determinar, respectivamente, um primeiro (MAFSV) e um segundo ( MAF FE) fluxos de ar de admissão em dito motor; e selecionar o dito primeiro (MAF SV) ou o dito segundo (MAF FE) fluxo de ar com base em um critério de seleção previamente definido.
