Abstract

DISPOSITIVO DE CONTROLE PARA MOTOR DE COMBUSTãO INTERNA E VEìCULO DO TIPO DE MONTAR INCLUINDO O MESMO. [Problema] Impedir o ruído anormal do motor depois do reabastecimento sem prover um sensor que detecta a razão de mistura de álcool, em um motor de combustão interna que pode usar um combustível misturado que é uma mistura de gasolina e álcool ou que pode usar seletivamente gasolina e álcool. [Modo para Resolução] Um dispositivo de controle para um motor de combustão interna inclui dispositivo de detecção de reabastecimento (S105) para detectar a presença ou a ausência do reabastecimento, dispositivo de estimativa de razão de mistura (S112) para estimar uma razão de mistura do álcool contido no combustível, dispositivo de determinação de conclusão de estimativa (S113) para determinar se a estimativa pelo dispositivo de estimativa da razão de mistura (S112) está concluída e dispositivo de controle de ignição (S107) para inflamar uma vela de ignição em uma regulação de ignição que é retardada de uma regulação de ignição ótima com base em uma razão de mistura real, durante um período predeterminado até que o dispositivo de determinação de conclusão de estimativa (S113) determina que a estimativa está concluida depois da detecção do reabastecimento.
