Abstract
PROCESSO PARA A OPERAçãO DE UMA MáQUINA DE COMBUSTãO INTERNA. A presente invenção refere-se a um processo para a operação de uma máquina de combustão interna com pelo menos dois cilindros, a qual pode ser operada com um combustível em qualidade de combustível diferente armazenado em um tanque, e/ou misturas de combustível armazenadas de um primeiro e pelo menos de um segundo combustível em relações de mistura do combustível diferentes, e sendo que qualidades de combustível diferentes e/ou misturas de combustível de composições diferentes exigem para a obtenção de uma combustão estável relações de ar/combustível diferentes, e/ou apresentam um comportamento de evaporação diferente. Neste caso está previsto, que em pelo menos um cilindro é realizada uma variação individual por cilindro da quantidade de combustível levada ao cilindro para uma mistura ar/combustível magra e/ou rica, que é avaliada a influência da variação sobre as características de partida e/ou a estabilidade da marcha do cilindro e/ou da máquina de combustão interna, e que no caso de um melhoramento obtido das características da partida e/ou da estabilidade da marcha é executada uma adaptação do combustível para todos os cilindros. O processo possibilita o reconhecimento rápido e a evitação de problemas de partida, quando de uma mudança da qualidade do combustível ou da composição do combustível, com efeito para a capacidade de ignição do combustível.
