Title:
内燃機関の燃料噴射制御装置
Document Type and Number:
Japanese Patent JP4024631
Kind Code:
B2
Abstract:
There will be provided a fuel injection control system for an internal combustion engine capable of obtaining an optimum fuel injection quantity in response to the traveling load without the need for any large memory capacity. The gear position discrimination unit (102) discriminates the present gear position (Ngp) on the basis of the vehicle speed (Vpls) and the engine speed (NE). The Kgpd calculation unit (103) calculates the correction factor by gear (Kgpd) on the basis of the gear position (Ngp) and the engine speed (NE). The state judgment unit (104) judges whether the engine is in a steady state or in a transient state. The map selection unit (105) selects, on the basis of the judgment result of the engine state, the PB map (11) or the TH map (12) as a map for determining the basic injection quantity (Ti). The basic injection quantity determination unit (106) determines the basic injection quantity (Ti) on the basis of a product of the PB map (11) or TH map (12) and the correction factor by gear (Kgpd).
