Fuel supply control method at deceleration time in internal combustion engine
专利汇可以提供Fuel supply control method at deceleration time in internal combustion engine专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain stable engine action by setting a predetermined operation region by a predetermined value of different pressure in an intake pipe at the time of rushing into a fuel supply stop and at the time of releasing the fuel supply stop, in the case of an engine whose fuel supply is stopped when the engine is placed in the predetermined operation region at deceleration time of the engine.
CONSTITUTION: In an ECU5 at the time of operating an engine 1, fuel injection time of a fuel injection valve 6 is calculated being based on various engine parameter signals. While the engine is discriminated for whether it is placed in a predetermined fuel cut operation region or not, when discrimination of YES is obtained, fuel injection from the fuel injection valve 6 is stopped. In this fuel cut control, when a throttle valve opening by an opening sensor 4 is in not less than a predetermined value, a fuel cut discrimination value of intake pipe absolute pressure in accordance with an engine speed by a speed sensor 10 is read from a ROM. This fuel cut discrimination value is set by a different predetermined value of intake pipe pressure at the time of rushing into a fuel supply stop and at the time of releasing the fuel supply stop.
