Abstract

PROCESSO E DISPOSITIVO PARA ACIONAR UM MOTOR DE COMBUSTÃO INTERNA QUE FUNCIONA COM ÁLCOOL E COMBUSTÍVEIS ADITIVADOS COM ÁLCOOL. O motor de combustão interna apresenta vários cilindros (Z1-Z4), aos cilindros (Z1-Z4) estão associados dispositivos de aquecimento de cilindros individuais para aquecimento do combustível. Quando do preenchimento de um critério (SA), que é indicativo de uma partida iminente do motor de combustão interna e, quando do preenchimento de critério (TKW_SW1), que permite concluir sobre partida a frio do motor de combustão interna, os dispositivos de aquecimento de cilindros individuais são ativados. Cada um dos dispositivos de aquecimento de cilindros individuais é checado quanto à sua função normal. Quando de um defeito constatado de um dispositivo de aquecimento, interrompe-se a alimentação de combustível ao cilindro (Z1-Z4) ao qual está associado o dispositivo de aquecimento defeituoso. O motor de combustão interna tem partida com um número de cilindros (Z1-Z4) reduzido na medida do número de dispositivos de aquecimento defeituosos. Durante a operação do motor de combustão interna, pelo menos uma grandeza correlacionada com temperatura do motor de combustão interna (TKW, N) é monitorada. Quando se ultrapassa um valor limite predeterminado (TKW_SW3, N_SW) para a dita pelo menos uma grandeza correlacionada (TKW, N), libera-se a alimentação de combustível ao cilindro (Z1-Z4) ao qual está associado o dispositivo de aquecimento defeituoso, e os dispositivos de aquecimento são desativados.PROCESS AND DEVICE FOR STARTING AN INTERNAL COMBUSTION ENGINE THAT WORKS WITH ALCOHOL AND ALCOHOL ADDED FUELS. The internal combustion engine has several cylinders (Z1-Z4), the cylinders (Z1-Z4) are associated with heating devices of individual cylinders for heating the fuel. When a criterion (SA) is fulfilled, which is indicative of an imminent start of the internal combustion engine, and when a criterion (TKW_SW1) is fulfilled, which allows to conclude about a cold start of the internal combustion engine, the heating devices of individual cylinders are activated. Each of the individual cylinder heating devices is checked for normal function. In the event of a defect found in a heating device, the fuel supply to the cylinder (Z1-Z4) to which the defective heating device is associated is interrupted. The internal combustion engine starts with a reduced number of cylinders (Z1-Z4) in proportion to the number of defective heating devices. During internal combustion engine operation, at least one quantity correlated with internal combustion engine temperature (TKW, N) is monitored. When a predetermined threshold value (TKW_SW3, N_SW) is exceeded for said at least one correlated quantity (TKW, N), the fuel supply to the cylinder (Z1-Z4) to which the defective heating device is associated is released, and heating devices are turned off.
