Abstract

resumo "sistemas e métodos para fornecimento de tubagem" trata-se de um dispositivo de controle para um motor de combustão interna que é configurado para executar um controle de corte de combustível e um controle de diagnóstico de anomalia. um dispositivo calefator para aquecer um elemento de um sensor de razão ar-combustível é controlado fazendo com que uma temperatura de elemento do sensor de razão ar-combustível assuma uma temperatura de elemento almejada. a temperatura de elemento almejada do sensor de razão ar-combustível durante um período de controle de temperatura alta, que vai desde um tempo quando um controle de temperatura alta prescrito começa após a partida do motor de combustão interna até um tempo quando o controle de temperatura alta prescrito é concluído após a conclusão do controle de diagnóstico de anomalia do sensor de razão ar-combustível, é definida para ser mais alta que a temperatura de elemento almejada fora do período de controle de temperatura alta.
