ABSTRACT:
In a multi-fuel engine which is operated on gasoline, alcohol or a mixture of the two, upon an alcohol sensor being diagnosed as being out of order, an alcohol correction factor in the injection pulse width calculation is clamped at an arbitrary value and in the case of high load operation a carburetion correction factor is incrementally increased instead of being set to a pre-recorded value for the instant load.
