摘要： PURPOSE:To prevent speed change shocks at the time of changing speed by arranging a power transmission device between input and output shafts of a gear type transmission, thereby controlling transmitted torque, adjusting engine output, and synchronizing the input and output shafts. CONSTITUTION:When changing speeds from a 1st speed to a 2nd speed, a control circuit 8 controls so that an operational amount of an actuator 13 to a multiplate clutch 12 becomes commensulate with a generated torque measured by an opening degree of a throttle valve 2. And two transmitting routes are arranged: a 1st speed route is an input shaft 5 a 1st speed gear 29 a sleeve 28 an output shaft 14 and the other is a gear 34 of the multiplate clutch 12. Then, when an actuator 17 is turned off and the sleeve 28 is brought to a neutral position to increase the transmitted torque of the clutch 12, rpm of an engine comes down. When the speed change ratio reaches that of a 2nd speed according to rpm sensors 7 and 27, the sleeve 28 and a 2nd speed gear 36 are connected to each other by means of the actuator 17, and the clutch 12 is turned off. Thus, the speed change time is shortened and the speed change shocks do not occur.

摘要： PURPOSE:To measure the injecting amount of fuel correctly without being affected by bubble in the fuel by a method wherein the bubble in the fuel is discharged out of an outlet port provided at the upward side surface of opening of a fuel inlet port at the side surface of a fuel injection valve. CONSTITUTION:The injection valve 10 is provided with the outlet opening 24. The bubble in the fuel is introduced into the injection valve 10 and moves upwardly from the inlet opening, then, is discharged out of the outlet opening 24 together with a part of the fuel thereby preventing the movement of the bubble into the direction of a nozzle 22. The fuel injection amount is measured by the time width of the opening of the fuel injection valve 10 and the measurement becomes correct since the net fuel, not including the bubble, is injected during the time width described above.

摘要： PURPOSE:To control engine speed stably by reducing suction air flow at least for the delay time until fuel supply will increase upon dropping of engine speed during idling thereby preventing increase of air/fuel ratio. CONSTITUTION:A controller 520 comprising a microcomputor will decide whether it is normal idling or warm-up operation from water-temperature through a sensor 511 and engine speed through crank angle sensor 620 to determine fuel injection and bypath throttle valve 516 opening in accordance with the difference between each target speed and actual speed. Upon dropping of engine revolution, suction air flow is reduced at least for the delay time untill fuel supply increase to prevent increase of air/fuel ratio. In such a manner, variation of air/fuel ratio during idling can be prevented to control engine speed stably under idling.
