Abstract

dispositivo de controle para motor de combustão interna e veículo de duplo suporte. prevenir batida após o reabastecimento sem instalar um sensor que detecte a razão de mistura do etanol, em um motor de combustão interna que possa utilizar um combustível misturado que é uma mistura de gasolina e álcool ou que possa utilizar seletivamente gasolina e álcool. um dispositivo de controle para um motor de combustão interna inclui um dispositivo de detecção de reabastecimento (s105) para detectar a presença ou ausência de reabastecimento, um dispositivo de estimação de razão de mistura (s112) para estimar a razão de mistura do álcool contido no combustível, um dispositivo de determinação de término de estimação (s113) para determinar se a estimação foi completada pelo dispositivo de estimação de razão de mistura (s112) e um dispositivo de controle de ignição (s107) para inflamar um inflamador a uma sincronização de ignição que é retardada a partir de uma sincronização de ignição ótima baseada na razão de mistura real, durante um período predeterminado, até que o dispositivo de determinação de término de estimação (s113) determine que a estimação está concluída após a detecção do reabastecimento.
