Abstract

DISPOSITIVO E MÉTODO PARA CONTROLAR UM MODULO PARA AQUECER UM PLURALIDADE DE INJETORES. Um método, e dispositivo associado, para controle de um módulo para o aquecimento de uma pluralidade de injetores de combustível de um motor de um veículo, referido módulo de aquecimento compreendendo uma pluralidade de meios de indução eletromagnética cada um deles conectado a um injetor da pluralidade de injetores de combustível e sendo configurado, quando uma corrente de excitação elétrica passa através dos referidos meios de indução eletromagnética, para aquecer referido injetor por indução, referido método compreendendo um passo de gerar uma corrente de alimentação elétrica e um passo de gerar, a partir da corrente de alimentação elétrica, uma pluralidade de correntes de excitação elétrica de fase deslocada em relação a cada outra e materializadas por sinais de corrente de excitação elétrica, cada uma das referidas correntes de excitação elétrica sendo destinada a fornecer um dos meios de indução eletromagnética da pluralidade de meios de indução eletromagnética. 0 método sendo notável pelo fato dos sinais de corrente de excitação elétrica (H1, H2, H3, H4) serem deslocados de tal forma que a soma dos valores absolutos das amplitudes (I) dos referidos sinais é constante.
