Title:
ルックアップテーブルの調整方法および燃焼エンジン内のシリンダの噴射器を制御するシステム
Document Type and Number:
Japanese Patent JP2009533583
Kind Code:
A
Abstract:
A method for adjusting a lookup table that includes preset on-time values for an injector of an engine linked to fuel injection quantity values (δ). The following steps are executed in a situation when the output shaft of the engine is disconnected from the output shaft of the gearbox. A torque loss value (Tloss) and a combustion efficiency value (εF) are determined or received. An actual fuel injection quantity value (δactual) is calculated, based on the torque loss value and the combustion efficiency value. An on-time value (tg) linked to the actual fuel injection quantity value is determined from the lookup table and the on-time value is compared with a presently applied on-time value (tb) that is established by an engine control with the aid of a regulator and the lookup table. The lookup table is adjusted based on the result of the comparison.
