内燃機関用噴射量制御装置
Document Type and Number:
Japanese Patent JP4089244
Kind Code:
B2
Abstract:
A fuel injection is carried out as n split injections. Each of injection quantities is defined by dividing an injection quantity into n fuel injections. A FCCB correction and an ISC correction are carried out while n split injection cycles are performed. A value obtained by adding up an FCCB correction ( DELTA Qc/n) for each injection cycle and an ISC correction (QISC/n) for each injection cycle is updated and stored as a learned injection quantity. The learned injection quantity is calculated as an injection quantity correction for each cylinder to be added to a command injection quantity (total-Q/n) for each injection cycle.
