摘要： According to the present invention, each of the cylinders of an engine is provided with a first and a second swirl ports for generating a swirl of intake air in the cylinder. The second swirl port is located at the position downstream of the first swirl port with respect to the direction of swirl generated by the first intake port. The helical air passages of the first and the second intake port have a bottom which opens to the cylinder and an upper wall facing the bottom and an end wall defining the end of the helical air passage. The angle .theta..sub.1 between the upper wall and the end wall of the helical air passage of the first (upstream) intake port is formed smaller than the same (the angle .theta..sub.2) of the helical air passage of the second (downstream) intake port. By forming the angle .theta..sub.1 small, intake air flowing through the first intake port rotates a large amount before it flows into the cylinder and a strong swirl is formed by the intake air from the first intake port. On the other hand, since the angle .theta..sub.2 is relatively large, intake air flowing through the second intake port flows into the cylinder before it rotates sufficiently. Therefore, the intake air from the second intake port flows into the cylinder without interfering with the swirl in the cylinder. Thus, the flow resistance of the second intake port decreases.
摘要翻译：根据本发明，发动机的每个气缸设置有用于在气缸中产生进气的涡流的第一和第二涡旋口。第二旋流口相对于由第一进气口产生的涡流的方向位于第一涡流口的下游位置。第一和第二进气口的螺旋空气通道具有通向气缸的底部和面向底部的上壁和限定螺旋空气通道的端部的端壁。第一（上游）进气口的螺旋空气通道的上壁和端壁之间的角度θ1形成为小于第二（下游）进气口的螺旋空气通道的角度θ1 。通过形成角度θ1，流过第一进气口的进气在其流入气缸之前大量旋转，并且来自第一进气口的进气形成强烈的涡流。另一方面，由于角度θ2相对较大，流过第二进气口的进气在其充分旋转之前流入气缸。因此，来自第二进气口的吸入空气流入气缸而不影响汽缸内的涡流。因此，第二进气口的流动阻力减小。

摘要： A sequential turbocharger system for an internal combustion engine with an exhaust gas recirculation system. The sequential system includes a large-volume turbocharger and a small-volume turbocharger, which are arranged in series in the direction of the flow of gases. A bypass passageway is connected to an exhaust pipe to thereby bypass the turbine of the small-volume turbocharger, and an exhaust switching valve is arranged in the bypass passageway for controlling the flow of exhaust gas to the turbine of the small-volume turbocharger. The EGR system includes an exhaust gas recirculation passageway for introducing an amount of exhaust gas into the intake pipe of the engine. The exhaust gas for recirculation is taken out from the intake pipe at a position located between the turbines of the small-volume and large-volume turbochargers.

On the event of a rapid acceleration, a rapid change in the combustion noise in the initial stage of the acceleration is prevented to improve driving comfort.
