Title
(EN) EXHAUST-GAS TURBOCHARGER HAVING A WASTEGATE DEVICE
(ZH) 具有废气门装置的排气涡轮增压器
Abstract
(EN)
The invention relates to an exhaust-gas turbocharger for an internal combustion engine (1), having a turbine (2), having a compressor wheel (4), which is connected to said turbine by way of a shaft, and having a wastegate device (8), which wastegate device has a wastegate actuator (5), has a wastegate drive shaft (7) rotatable about an axis of rotation (6), and has a flap (20a, 20b, 20c, 20d, 20e,20f, 20g) which is fastened to said drive shaft and which is pivotable about the axis of rotation and which has a covering surface (9) for potentially opening up and closing off a wastegate opening (10a), wherein the wastegate flap and the wastegate opening (10a) that can be closed off by way of said wastegate flap are designed such that the spacing from the centre of area (11, 1a) of the covering surface (9), which covers the wastegate opening, of the wastegate flap to the axis of rotation (6) is smaller than the radius of a circular surface of equal surface area.
