Abstract

resumo "sistema de controle para motor de combustão interna” um objetivo da invenção é fornecer uma tecnologia pertencente a um siste-ma de controle para um motor de combustão interna utilizando cng para permitir que um motor de combustão interna opere de forma adequada mesmo quando as propriedades do cng mudam. para se alcançar esse objetivo, no sistema de controle para um motor de combustão interna utilizando o gás natural comprimido de acordo com a invenção, quando o controle de retorno de razão de ar para combustível que corrige a quantidade de injeção de combustível de tal forma a tornar a razão de ar para combustível da mistura de ar para combustível queimada no motor de combustão interna substancialmente igual a uma razão de ar para combustível alvo, um parâmetro de controle referente a uma condição de combustão da mistura de ar para combustível é corrigido com base na magnitude do valor de correção no controle de retorno de razão de ar para combustível.
