  • a pair of left and right side covers 32 covering the rear lower part of the fuel tank 23 from both the left and right sides are continuous between the fuel tank 23 and the front seat 24a for riding.
  • the seat frame 18 is covered with a rear cowl 33 below the rear seat 24b for riding.
  • the valve opening degree setting means 84 is connected to an opening degree sensor 75 of an electronically controlled throttle device 63.
  • the valve opening setting means 84 specifies the actual opening of the throttle valve 71 based on the detection signal from the opening sensor 75.
  • valve opening setting means 84 forgets to fix the opening of the throttle valve 71 in the low rotation range of the internal combustion engine 25. At this time, the valve opening setting means 84 continues to output a signal for designating the target opening in accordance with fluctuations in the operation amount of the right handle grip 78.
  • the low rotation range of the internal combustion engine 25 can be set to 2000 rpm or less, for example.
  • the low rotation range of the internal combustion engine 25 may be set to 1/2 or 1/3 of the maximum rotation, or may be set to be equal to or less than the rotation speed during idling.
  • the rotational speed of the internal combustion engine 25 is calculated based on the angular position signal from the angular position detection means 87.
  • the valve opening setting means 84 calculates the difference between the actual opening of the throttle valve 71 and the target opening in step S1.
  • the target opening obtained in the previous calculation is used as the target opening. If the deviation between the actual opening and the target opening is equal to or greater than a predetermined threshold, the valve opening setting means 84 acquires the operation amount of the right handle grip 78 from the operation amount detection means 86 in step S2.
  • the valve opening setting means 84 sets the opening (target opening) of the throttle valve 71 in proportion to the operation amount.

  • the valve opening setting means 84 outputs a control signal toward the actuator 74 in step S4.
  • the valve opening setting means 84 confirms the closing timing of the intake valve 55 in step S11. If it is not the closing timing, the processing operation of the control device 83 proceeds to step S10. Therefore, the target opening is kept in the buffer. Based on the target opening thus held, the valve opening setting means 84 generates a control signal.
  • the valve opening setting means 84 stops fixing the target opening in the low rotation range of the internal combustion engine 25.
  • the opening of the torque request value obtained by operating the right handle grip 78 and the actual torque is suppressed, and the rider's uncomfortable feeling can be avoided as much as possible.
  • the rider will feel more uncomfortable than in the high rotation range.

Abstract

Un dispositif de commande (83) pour un moteur à combustion interne (25) comprend un moyen de détection de puissance de fonctionnement(86) qui détecte la puissance de fonctionnement d'un accélérateur (78), et un mécanisme de réglage de position de soupape (84) qui modifie la position d'un étrangleur (71) en fonction de la fluctuation de la puissance de fonctionnement, et délivre un signal qui immobilise la position de l'étrangleur (71) à partir du début du calcul de la quantité d'injection de carburant cible jusqu'à ce qu'une soupape d'admission (55) se ferme. Le dispositif de commande (83) maintient la position de l'étrangleur (71) pendant l'injection de carburant, indépendamment de la fluctuation de la puissance de fonctionnement de l'accélérateur (78).
