| 摘要： | 一种内燃发动机，包括：缸体，限定汽缸；缸盖；排气集管，操作地连接到缸盖且配置为从汽缸排出燃烧后气体。发动机还包括涡轮增压系统，配置为对用于输送到汽缸的空气流加压。该涡轮增压系统包括低流量涡轮增压器，具有第一涡轮壳体；高流量涡轮增压器，具有第二涡轮壳体。每个涡轮增压器被配置为由来自排气集管的燃烧后气体驱动，以加压空气流，并将加压的空气流排放到汽缸。该涡轮增压系统还包括流动控制装置，用于选择性地引导燃烧后气体到低流量和高流量涡轮增压器。涡轮增压系统附加地包括冷却模块，配置为冷却第二涡轮壳体。还公开了使用这样的发动机的车辆。 | ||
| 摘要(英文)： | An internal combustion engine includes a cylinder block defining a cylinder, a cylinder head, and an exhaust manifold operatively connected to the cylinder head and configured to exhaust post-combustion gasses from the cylinder. The engine also includes a turbocharging system configured to pressurize an airflow for delivery thereof to the cylinder. The turbocharging system includes a low-flow turbocharger having a first turbine housing and a high-flow turbocharger having a second turbine housing. Each turbocharger is configured to be driven by the post-combustion gasses from the exhaust manifold in order to pressurize the airflow and discharge the pressurized airflow to the cylinder. The turbocharging system also includes a flow control device for selectively directing the post-combustion gasses to the low-flow and high-flow turbochargers. The turbocharging system additionally includes a cooling module configured to cool the second turbine housing. A vehicle employing such an engine is also disclosed. | ||
