Abstract:
(EN) This internal combustion engine (1) comprises: a variable compression ratio mechanism (2) which varies the mechanical compression ratio; and a variable valve timing mechanism (7) which varies the valve timing of the intake valve (4). If there is a demand for learning at the reference position for the system calibration of the variable valve timing mechanism (7) (step 21), learning is enabled under the condition that the mechanical compression ratio is higher than a threshold value VCRth (step 22). If there is an abnormality of some type in the variable compression ratio mechanism 2, learning of the variable valve timing mechanism (7) is disabled (steps 23, 25).
(FR) L'invention concerne un moteur à combustion interne (1), lequel moteur comprend un mécanisme à taux de compression variable (2) qui modifie un taux de compression mécanique, et un mécanisme de calage de distribution variable (7) qui modifie le calage de distribution d'une soupape d'admission (4). S'il existe une demande d'apprentissage à la position de référence pour l'étalonnage du système du mécanisme de calage de distribution variable (7) (étape 21), l'apprentissage est permis à condition que le rapport de compression mécanique soit supérieur à une valeur de seuil VCRth (étape 22). S'il existe une anomalie d'un certain type pour le mécanisme à taux de compression variable 2, l'apprentissage du mécanisme de calage de distribution variable (7) est désactivé (étapes 23, 25).
(JA) 内燃機関(1)は、機械的圧縮比を変更する可変圧縮比機構(2)と、吸気弁(4)のバルブタイミングを変更する可変バルブタイミング機構(7)と、を有する。可変バルブタイミング機構(7)のシステムの較正のための基準位置での学習が要求(ステップ21)されたときに、機械的圧縮比が閾値VCRthよりも高い(ステップ22)ことを条件として学習を許可する。可変圧縮比機構2に何らかの異常がある場合には、可変バルブタイミング機構(7)の学習は禁止する(ステップ23,25)。
