Claims (1)
通路に設けたコンプレツサを駆動するようにした
エンジンの排気ターボ装置であつて、タービン上
流の排気通路を、常時開放される低速用通路と開
閉制御される高速用通路とに分けると共に、前記
低束用通路には、タービンを迂回してタービン下
流の排気通路に接続されるバイパス通路と、過給
圧を推定値以下にするように上記バイパス通路を
開閉制御するウエストゲートバルブとを設け、か
つ前記低速用通路の上流側開口面積を前記高速用
通路の上流側開口面積より大きく形成したことを
特徴とするエンジンの排気ターボ装置。 This is an engine exhaust turbo device in which the output of a turbine installed in the exhaust passage drives a compressor installed in the intake passage, and the exhaust passage upstream of the turbine is controlled to open and close as a low-speed passage that is always open. The low-flux passage is divided into a high-speed passage and a bypass passage that bypasses the turbine and is connected to the exhaust passage downstream of the turbine, and the bypass passage is opened and closed to reduce the boost pressure to an estimated value or less. What is claimed is: 1. An exhaust turbo device for an engine, comprising: a waste gate valve to be controlled; and an upstream opening area of the low-speed passage is larger than an upstream opening area of the high-speed passage.
