Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel injector wear correction methodology.SOLUTION: A fuel injector wear methodology for use with internal combustion engines includes a method of: determining power of the engine and/or a fuel flow of a fuel injector associated with a cylinder of the engine; obtaining a duration of a fuel injection event from the injector associated with the cylinder of the engine; comparing the power, the fuel flow, and/or the duration with a reference value; and then adjusting the fuel injection timing of the fuel injector on the basis of the comparison. Another method of adjusting operation of an engine includes: comparing two (or more) engine models, where one model is related to a fuel injection event duration of the engine or a modeled fuel quantity being supplied to the engine; and then adjusting the fuel injection timing of a fuel injector of the engine on the basis of the comparison.SELECTED DRAWING: Figure 1 【課題】燃料噴射器の摩耗を修正する方法を提供すること。【解決手段】内燃エンジンに使用する燃料噴射器の摩耗の方法は、エンジンの動力及び／又はエンジンのシリンダに関連付けられた燃料噴射器の燃料の流れを決定し、エンジンのシリンダに関連付けられた噴射器から燃料噴射イベントの持続時間を取得し、動力、燃料の流れ、及び／又は持続時間を基準値と比較し、次いで、この比較に基づいて燃料噴射器の燃料噴射タイミングを調整する、方法を含む。エンジンの動作を調整する別の方法は、１つのモデルが、エンジンの燃料噴射イベントの持続時間又はエンジンに供給されているモデル化した燃料量に関係する、２つ（又はそれ以上）のエンジンモデルを比較することと、次いで、比較に基づいてエンジンの燃料噴射器の燃料噴射タイミングを調整することを含む。【選択図】図１
