INJECTION CONTROL SYSTEM OF INTERNAL COMBUSTION ENGINE |
摘要 |
An electronic control unit (ECU) of an engine calculates a first modification value for decreasing a correction value of an injection period when a state variation of the engine caused by a single injection is greater than a target value. The ECU calculates a second modification value for increasing the correction value when the state variation is less than the target value. The second modification value is greater than the first modification value. Thus, a period necessary to converge the correction value can be shortened when the correction value is increased. The first modification value is increased if a difference between the state variation and the target value exceeds a permissible value when the correction value is decreased. Thus, the injection quantity is decreased quickly to prevent excessive fuel injection.
