Abstract

DISPOSITIVO DE CONTROLE PARA MOTOR DE COMBUSTãO INTERNA. A presente invenção refere-se a um dispositivo de controle de motor de combustão interna tendo um dispositivo de controle de proporção de ar-combustível que controla a quantidade de injeção de combustível de modo que a proporção de ar-combustível do gás de exaustão do motor de combustão interna aproxime-se de uma proporção de ar-combustível estequiométrica alvo, o dispositivo de controle incluindo ainda um dispositivo que calcula o valor calorífico inferior de combustível, e um dispositivo que ajusta a proporção de ar-combustível estequiométrica alvo do valor calorífico inferior calculado com base em uma relação conhecida (figura 2) entre o valor calorífico inferior e a proporção de ar-combustível estequiométrica. Torna-se possível realizar o controle de proporção de ar-combustível de acordo com a propriedade de combustível utilizando a relação entre o valor calorífico e a proporção de ar-combustível estequiométrica.
