Title:
燃料噴射制御装置
Document Type and Number:
Japanese Patent JP4001319
Kind Code:
B2
Abstract:
To allow an engine having an intake duct for drawing running air to produce a high output by performing appropriate fuel injection depending on dynamic pressure variations. A vehicle speed corrective coefficient calculator calculates a fuel corrective coefficient KVPLS based on a vehicle speed VPLS, and a throttle corrective coefficient calculator calculates a corrective coefficient KVthetaTH based on a throttle opening thetaTH. A corrective coefficient multiplier multiplies the fuel corrective coefficient KVPLS and the corrective coefficient KVthetaTH, thus calculating a vehicle speed fuel adjustment corrective coefficient KVAF. An injection time calculator calculates a basic injection time TiM based on the throttle opening thetaTH and an engine rotational speed Ne, and also calculates a fuel injection time Ti by reading the vehicle speed fuel adjustment corrective coefficient KVAF and correcting the basic injection time TiM. When the engine rotational speed Ne is equal to or higher than a predetermined value Ne1 and also when the transmission is shifted to a low gear position, a corrective coefficient KVAF signal is applied to the injection time calculator.
