Method for controlling the valve lift of discretely adjustable inlet valves in a multi-cylinder internal combustion engine

   
   

To avoid a sudden change in torque when switching over the valve lift of discretely adjustable inlet valves, the valve lift is firstly only adjusted for a section of cylinders, while the valve lift for the remaining section of cylinders is switched over after a delay. Therefore with each valve lift adjustment, only a slight change in torque has to be compensated by means of a corresponding change in the efficiency of the cylinders.

Pour éviter un changement soudain de couple en commutant au-dessus de l'ascenseur de valve des soupapes d'admission discretely réglables, l'ascenseur de valve premièrement est seulement ajusté à une section des cylindres, alors que l'ascenseur de valve pour la section restante des cylindres est commuté plus d'après un retarder. Par conséquent avec chaque ajustement d'ascenseur de valve, seulement un léger changement de couple doit être compensé au moyen d'un changement correspondant de l'efficacité des cylindres.
