    • An engine is provided with a primary turbocharger and a secondary turbocharger having blowers disposed in the intake passage of the engine in parallel to each other and turbines disposed in the exhaust passage of the engine in parallel to each other. An exhaust cutoff valve disposed in the exhaust passage opens to feed exhaust gas to the turbine of the secondary turbocharger to operate the secondary turbocharger only in a large intake air mass range. A waste gate valve opens to relieve exhaust gas fed to the turbochargers when the supercharging pressure exceeds a predetermined value. The waste gate valve is kept closed for a predetermined time after the operating condition of the engine shifts into the large intake air mass range and the exhaust cutoff valve opens when shift of the operating condition of the engine from a small intake air mass range to the large intake air mass range is required.
    • 发动机设置有主涡轮增压器和二次涡轮增压器,其具有彼此平行地布置在发动机的进气通道中的鼓风机和布置在发动机的排气通道中的涡轮彼此平行。 设置在排气通道中的排气截流阀打开以将排气供给到二次涡轮增压器的涡轮机,以仅在大的进气质量范围内操作次级涡轮增压器。 当增压压力超过预定值时,废门阀打开以减轻供给涡轮增压器的废气。 在发动机的运转状态变为大的进气质量范围之后,废气闸阀保持关闭预定的时间,并且当发动机的运行状态从小的进气空气质量范围转移到 需要大的进气空气质量范围。
