Filed: 2007-08-22
Abstract: <P>PROBLEM TO BE SOLVED: To set ignition timing at a proper value corresponding to a mixed ratio of different fuel when the different fuel is mixed in fuel supplied to an engine.  <P>SOLUTION: When it is determined that the different fuel is mixed in the fuel supplied to the engine, the mixed ratio of the different fuel is estimated, the ignition timing is set at optimum ignition timing MBT by varying the ignition timing to an advance side corresponding to that more the mixed ratio of the different fuel is high, more the optimum ignition timing MBT (ignition timing at which torque is most efficiently generated) varies to the advance side. If knocking does not occur, the ignition timing (MBT) corresponding to the mixed ratio of the different fuel is used as it is. On the other hand, if knocking occurs, the ignition timing is corrected to a retard side until knocking does not occur. With this, when the different fuel is mixed, within a range that knocking does not occur, the ignition timing is set to the advance side so that torque is generated as efficiently as possible.  <P>COPYRIGHT: (C)2009,JPO&INPIT
