Title (EN) ENGINE SYSTEM
(FR) SYSTÈME DE MOTEUR
(JA) エンジンシステム
Abstract:
(EN) Provided is an engine system in which an exhaust gas recirculation (EGR) control unit: acquires a plurality of engine state quantities, from among target engine rotational rate, engine load, scavenging pressure, and overcharger rotational rate; calculates individual optimal EGR gas flow rates from map data stored in advance on the basis of the values of each of the acquired engine state quantities; selects the smallest of the calculated plurality of individual optimal EGR gas flow rates as the optimal EGR gas flow rate; and generates a control signal on the basis of the selected optimal EGR gas flow rate.
(FR) L'invention concerne un système de moteur dans lequel une unité de recirculation de gaz d'échappement (EGR) : acquiert une pluralité de quantités d'état de moteur, parmi une vitesse de rotation cible du moteur, une charge de moteur, une pression de balayage et une vitesse de rotation de turbocompresseur ; calcule des débits d'écoulement de gaz de recirculation de gaz d'échappement optimaux et individuels à partir de données de carte, stockées à l'avance, sur la base des valeurs de chacune des quantités d'état de moteur acquises ; sélectionne le plus petit de la pluralité calculée de débits d'écoulement de gaz de recirculation de gaz d'échappement optimaux et individuels comme débit d'écoulement de gaz de recirculation de gaz d'échappement optimal ; génère un signal de commande sur la base du débit d'écoulement de gaz de recirculation de gaz d'échappement optimal sélectionné.
(JA) エンジンシステムのEGR制御部は、目標エンジン回転数、エンジン負荷、掃気圧、及び過給機回転数のうち複数のエンジン状態量を取得し、取得した各エンジン状態量の値に基づいて、予め記憶したマップデータから個別最適EGRガス流量をそれぞれ算出し、算出した複数の個別最適EGRガス流量のうち最も小さいものを最適EGRガス流量に選定し、選定した最適EGRガス流量に基づいて制御信号を生成する。
