Fuel supply control control equipment null of assist air feeder attaching internal combustion

摘要

PURPOSE: To prevent production of the change of an air-fuel ratio owing to the feed and cut-off of assist air. ;CONSTITUTION: When assist air is fed, a correction factor KAATP is set at S1-S7 based on a fundamental injection pulse Tpo. After a fundamental injection pulse width is corrected by means of the set correction factor KAATP, a effective pulse width Teo is computed at S8 based on a fundamental injection pulse width Tp after the correction. Based on the computed effective pulse width, a correction factor KAATE is set to correct the effective pulse width, and a final injection pulse width Ti is computed at S9-S11 by adding a battery voltage correction value Ts to an effective pulse width Te after correction. This constitution causes suppression of production of a difference in a fuel injection amount between the same injection pulses owing to the feed and cut-off of assist air.;COPYRIGHT: (C)1994,JPO&Japio
