• Warm-up enrichment
When the coolant temperature is low, a warm-up coefficient is applied in accordance with the sig-
nals from the coolant temperature sensor in order to effect fuel enrichment. Because the coolant
temperature determines the coefficient, the coefficient changes with the fluctuations in the coolant
temperature. The coefficient increases with the decrease in the coolant temperature, and decreases
with the increase in the coolant temperature. The ratio of fuel enrichment also changes with the
changes in the coefficient.
