SYSTEM FOR DUALIZING CONDITION FOR ENTRY INTO FUEL CUT AND METHOD FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a system for dualizing a condition for entry into a fuel cut and a method for the same, that can improve fuel economy and comply with NOx regulations by adjusting standards for entering a fuel cut according to the temperature of a catalyst.SOLUTION: A system for dualizing a condition for entry into a fuel cut of the invention comprises a control part 100 that receives transmission of a temperature of a catalyst in a catalytic converter 200 as a model temperature value and then determines whether the temperature is within a temperature range in which the catalyst can be activated. The control part 100 changes the condition for entry into a fuel cut according to the catalyst temperature which the control part receives transmission as the model temperature value.SELECTED DRAWING: Figure 3
