FUEL INJECTION CONTROL DEVICE |
摘要 |
A fuel injection control device is a control device controlling an injection of fuel by a fuel injector and includes: a setting part that sets a request injection quantity of an injection quantity requested of the fuel injector; a dividing part that divides the request injection quantity set by the setting part into a specified injection quantity and an adjusting injection quantity other than the specified injection quantity; an injection performing part that performs a dividing injection of an adjusting injection and a partial lift injection by the fuel injector, the adjusting injection injecting the adjusting injection quantity of fuel, the partial lift injection finishing a lift of a valve body of the fuel injector in a partial lift state before the valve body reaching a full lift position and injecting the specified injection quantity of fuel; and a learning part that learns an injection characteristic of the fuel injector at the time of the partial lift injection. |
