要約
(EN) This estimation device (80) is applied to a combustion system that has an internal combustion engine (10). The estimation device (80) is provided with a mixture acquisition unit (S101), a combustion amount estimation unit (S205), and a region estimation unit (S206). The mixture acquisition unit (S101) acquires the mixing ratios of various components included in a fuel that is used for combustion in the internal combustion engine. For a main combustion which is generated by the injection of fuel into a combustion chamber (11a) of the internal combustion engine by means of a main injection, the combustion amount estimation unit (S205) estimates, on the basis of the mixing ratios acquired by the mixture acquisition unit, a main fuel combustion amount (Qinj) arising from a main combustion. The region estimation unit (S206) estimates, on the basis of the mixing ratios acquired by the mixture acquisition unit, a combustion region for the main combustion in the combustion chamber.
(FR) Le présent dispositif d'estimation (80) est appliqué à un système de combustion comportant un moteur à combustion interne (10). Le dispositif d'estimation (80) est pourvu d'une unité d'acquisition de mélange (S101), d'une unité d'estimation de quantité de combustion (S205) et d'une unité d'estimation de région (S206). L'unité d'acquisition de mélange (S101) acquiert les rapports de mélange de divers constituants compris dans un carburant utilisé pour la combustion dans le moteur à combustion interne. Pour une combustion principale générée par l'injection de carburant dans une chambre de combustion (11a) du moteur à combustion interne au moyen d'une injection principale, l'unité d'estimation de quantité de combustion (S205) estime, sur la base des rapports de mélange acquis par l'unité d'acquisition de mélange, une quantité de combustion de carburant principale (Qinj) résultant d'une combustion principale. L'unité d'estimation de région (S206) estime, sur la base des rapports de mélange acquis par l'unité d'acquisition de mélange, une région de combustion pour la combustion principale dans la chambre de combustion.
(JA) 推定装置(80)は、内燃機関(10)を有する燃焼システムに適用される。推定装置(80)は、混合取得部(S101)、燃焼量推定部(S205)、および領域推定部(S206)を備える。混合取得部(S101)は、内燃機関での燃焼に用いる燃料に含まれた各種成分の混合割合を取得する。燃焼量推定部(S205)は、燃料がメイン噴射により内燃機関の燃焼室(11a)に噴射されることで発生するメイン燃焼について、メイン燃焼による燃料のメイン燃焼量(Qinj)を、混合取得部により取得された混合割合に基づいて推定する。領域推定部(S206)は、燃焼室におけるメイン燃焼の燃焼領域を、混合取得部により取得された混合割合に基づいて推定する。
