Abstract
An engine injector control device and method include an opening delay calculation unit configured to receive a predetermined operating condition and an injection strategy. The opening delay calculation unit is further configured to determine an opening delay difference between an opening delay of a first injection and an opening delay of a subsequent injection of a plurality of subsequent injections following the first injection during a multi-stage injection by an injector. The engine injector control device and method also include an injector driving unit configured to operate the injector based on the opening delay difference determined in the opening delay calculation unit.
Claims20
An engine injector control device comprising:
- an opening delay calculation unit configured to:
- receive a predetermined operating condition and an injection strategy;
- and
- determine an opening delay difference between an opening delay of a first injection and an opening delay of a subsequent injection of a plurality of subsequent injections following the first injection during a multi-stage injection by an injector;
- and
- an injector driving unit configured to operate the injector based on the opening delay difference determined in the opening delay calculation unit.
An engine injector control device comprising:
- an injection time calculation unit configured to determine an injection time;
- an opening delay calculation unit configured to:
- receive a fuel rail pressure, a fuel temperature, a dwell time, and an injection time;
- and
- output an opening delay difference between an opening delay of a first injection and an opening delay of a subsequent injection of a plurality of subsequent injections following the first injection during a multi-stage injection by an injector;
- and
- an injector driving unit configured to operate the injector based on the opening delay difference provided from the opening delay calculation unit.
An engine injector control method comprising:
- determining an injection strategy of an injector by receiving a predetermined operating condition;
- determining an injection time of the injector according to the injection strategy;
- determining an opening delay difference between an opening delay of a first injection and an opening delay of a subsequent injection of a plurality of subsequent injections following the first injection according to the operating condition, the injection strategy, and the injection time during a multi-stage injection by the injector;
- and
- operating the injector by using the opening delay difference.
