Abstract

Método para aquisição e processamento de um sinal de pressão de admissão em um motor de combustão Interna sem um coletor de admissão. Método para aquisição e processamento de um sinal de pressão de admissão em um motor de combustão interna (1) sem um coletor de admissão; o motor de combustão interna (1) com pelo menos um cilindro (2) que recebe ar fresco através de um duto de admissão (3), que é controlado por uma válvula de borboleta (7) e é fornecido com um sensor de pressão (9) conectado a uma unidade de controle eletrónico (8). O método de aquisição e processamento providencia as seguintes etapas: medição, via o sensor de pressão (9), da pressão instantãnea de indução em uma pluralidade de diferentes ângulos de fenda distribuidos sobre um ciclo do motor; armazenamento, durante cada ciclo do motor, das pressões instantãneas de indução em uma memória de rápida aquisição (10) da unidade de controle eletrónico (8); e determinação, no final de cada ciclo do motor, da pressão média de indução no ciclo do motor ao calcular a média das pressões instantâneas de indução previamente armazenadas na memória de rápida aquisição (10) da unidade de controle eletrónico (8).
