    • An internal combustion engine with a dual turbocharger system includes an engine, a first turbocharger and a second turbocharger arranged in parallel with each other, an intake switching valve located downstream of a compressor of the second turbocharger, and an exhaust switching valve located downstream of a turbine of the second turbocharger. At large intake air quantities, both turbochargers are operated, while at small to medium intake air quantities only the first turbocharger is operated. At "one-turbocharger-operation", when the engine load is low, the intake switching valve is opened, while the exhaust switching valve is maintained closed. Thus, at small to medium intake air quantities and low engine loads, the intake flow can be introduced through both the compressor of the first turbocharger and the compressor of the second turbocharger. As a result, flow resistance is decreased and acceleration response from low engine loads is improved.
    • 具有双涡轮增压器系统的内燃机包括彼此并联布置的发动机,第一涡轮增压器和第二涡轮增压器,位于第二涡轮增压器的压缩机下游的进气切换阀和位于第二涡轮增压器下游的排气切换阀 第二涡轮增压器的涡轮机。 在大的进气量下,两个涡轮增压器都被操作,而在小到中等的进气量下,只有第一个涡轮增压器运行。 在“单涡轮增压器运转”中,当发动机负荷低时,进气切换阀打开,而排气切换阀保持关闭。 因此,在小到中等的进气量和低的发动机负荷下,可以通过第一涡轮增压器的压缩机和第二涡轮增压器的压缩机两者来引入进气流。 结果,流动阻力降低,并且来自低发动机负载的加速响应得到改善。

    • An internal combustion engine with a dual turbocharger system which includes an engine, a first and a second turbocharger arranged in parallel with each other, an intake switching valve located downstream of a compressor of the second turbocharger, an exhaust switching valve located downstream of a turbine of the second turbocharger. The engine operation is changed between a "one-turbocharger-operation" wherein only the first turbocharger is operated and a "two-turbocharger-operation" wherein both the first turbocharger and the second turbocharger are operated. Change from the "one-turbocharger-operation" to the "two-turbocharger-operation" is performed on the basis of an intake air quantity, and change from the "two-turbocharger-operation" to the "one-turbocharger-operation" is performed on the basis of an engine speed. This type of change suppresses a torque shock at shift changing during acceleration and improves the drive feeling.
    • 一种具有双涡轮增压器系统的内燃机,其包括发动机,彼此并联布置的第一和第二涡轮增压器,位于第二涡轮增压器的压缩机下游的进气切换阀,位于涡轮机下游的排气切换阀 的第二涡轮增压器。 发动机的运转在仅运转第一涡轮增压器的“单涡轮增压器运转”和运转第一涡轮增压器和第二涡轮增压器的“双涡轮增压器运转”之间发生变化。 基于进气量进行从“单涡轮增压器运转”到“双涡轮增压器运转”的变更,从“双涡轮增压器运转”变更为“一涡轮增压器运转” 是基于发动机转速进行的。 这种变化抑制加速过程中换档时的转矩冲击,提高驱动感。

    • An internal combustion engine with a dual turbocharger system which includes an engine, a first and a second turbocharger arranged in parallel with each other, an intake switching valve located downstream of a compressor of the second turbocharger, an exhaust switching valve located downstream of a turbine of the second turbocharger, and an exhaust bypass valve installed an exhaust bypass conduit bypassing the exhaust switching valve. The exhaust bypass valve is opened on the basis of a charging pressure at low engine speeds and is opened on the basis of an intake air quantity at high engine speeds. As a result of controlling the exhaust bypass valve in this fashion, a smooth transition from a "one-turbocharger-operation" to a "two-turbocharger-operation" can be obtained throughout the entire range of engine speeds.

    • An internal combustion engine with a dual turbocharger system includes a first turbocharger operated through an entire intake air quantity, a second turbocharger operated only at large intake air quantities, an exhaust bypass conduit bypassing a turbine of the second turbocharger, an exhaust bypass valve installed in the exhaust bypass conduit, and exhaust bypass valve opening control means for controlling at least one of a time to begin opening and a speed of opening the exhaust bypass valve. The exhaust bypass valve is opened before the turbocharger operation is switched from a "one-turbocharger-operation" to a "two-turbocharger-operation" so that the second turbocharger is run-up and a smooth transition can be obtained. The exhaust bypass valve begins to open at a lower charging pressure when a transmission gear position is low than when the gear position is high, a period of time for running-up the second turbocharger is lengthened so that the second turbocharger is sufficiently run-up and a torque shock at the transition form "one-turbocharger-operation" to "two-turbocharger-operation" is minimized.
    • 具有双涡轮增压器系统的内燃机包括通过整个进气量操作的第一涡轮增压器,仅在大的进气量下操作的第二涡轮增压器,绕过第二涡轮增压器的涡轮机的排气旁通管,安装在 排气旁通管道和排气旁通阀开度控制装置,用于控制开始打开的时间和排气旁通阀的打开速度中的至少一个。 在将涡轮增压器操作从“单涡轮增压器操作”切换到“双涡轮增压器操作”之前,排气旁通阀打开,使得第二涡轮增压器起动并且可以获得平稳的转变。 当传动档位低于档位高时,排气旁通阀开始以较低的充气压力打开,使第二涡轮增压器升高的时间段延长,使得第二涡轮增压器充分起动 并且将“单涡轮增压器运转”转换为“双涡轮增压器运转”的转矩冲击最小化。
