| description | PROBLEM TO BE SOLVED: To provide a PM generation amount estimation device for an internal combustion engine that can improve estimation accuracy of PM generation amount.SOLUTION: From injection timing of fuel injected from an injector and intake pressure, cylinder pressure at the fuel injection timing is calculated (Step ST2). Based on injection pressure and injection amount of the fuel injected from the injector and the cylinder pressure at the fuel injection timing, spray volume of the fuel is calculated (Step ST4). Based on the spray volume and an EGR rate, a spray air-fuel ratio is calculated (Step ST6). Based on the spray air-fuel ratio, PM generation amount is calculated (Step ST7). Thus, even during a transient operation of an engine, estimation accuracy of the PM generation amount can be improved. As a result, start timing of PM regeneration processing can be made appropriate.SELECTED DRAWING: Figure 4
【課題】ＰＭ発生量の推定精度の向上を図ることが可能な内燃機関のＰＭ発生量推定装置を提供する。【解決手段】インジェクタから噴射される燃料の噴射時期および吸気圧から燃料噴射時期での筒内圧力を算出する（ステップＳＴ２）。インジェクタから噴射される燃料の噴射圧力および燃料噴射量、燃料噴射時期での筒内圧力により、燃料の噴霧体積を算出する（ステップＳＴ４）。噴霧体積およびＥＧＲ率により、噴霧内空燃比を算出する（ステップＳＴ６）。噴霧内空燃比に基づいてＰＭ発生量を算出する（ステップＳＴ７）。これにより、エンジンの過渡運転時においてもＰＭ発生量の推定精度の向上を図ることが可能になる。その結果、ＰＭ再生処理の開始タイミングの適正化を図ることが可能になる。【選択図】図４ |
