The internal combustion engine includes a compressor for supercharging intake air, an EGR device for introducing EGR gas into an intake passage at a position on an upstream side relative to the compressor, and a collecting pocket that is provided at an outer circumference of a compressor inlet and that collects condensed water generated inside the intake passage on an upstream side relative to the compressor. The collecting pocket opens towards the upstream side of the compressor, and is formed in a circular ring shape that surrounds the outer circumference of the compressor inlet. The collecting pocket includes a partition wall that holds back a flow of condensed water that attempts to move in a downward gravitational direction inside an internal space of the collecting pocket.

A turbocharger includes a waste gate valve, a compressor with a turbine, a turbine housing which houses the turbine, a bypass channel with an opening cross-section, a bypass channel portion formed in the turbine housing, an actuator housing with a separate coolant channel, an electric motor arranged in the actuator housing, a transmission with an output shaft, the transmission being arranged in the actuator housing and being provided as a worm wheel gear unit, and a control body coupled to the output shaft of the transmission. The bypass channel bypasses the turbine. The actuator housing is removably secured to the turbine housing. The control body controls the opening cross-section of the bypass channel.

The present invention relates to a power transmission apparatus using a magnetic field, the power transmission apparatus comprising a rotor module, a front driver module and a rear driver module, or comprising a rotor module and any one of a front driver module and a rear driver module. The power transmission apparatus generates, using power received from a power applying driving body or power received from a power receiving driving body, rotational power from a combination of an induced magnetic field which the front driver module generates, a rotating magnetic field which the rotor module generates, and a rotating magnetic field which the rotor module generates together with the front driver module and the rear driver module, and acceleratedly rotates to increase the rotational power, thereby transmitting power to the power receiving driving body and to a target object.

An electric exhaust turbocharger (10) has a turbine wheel (12), a compressor wheel (14) that is non-rotatably connected to the turbine wheel (12), and an electric drive motor having a stator (30) and a rotor (54). The rotor (54) is fixed to a rotor shaft (52) and is connected non-rotatably to the turbine wheel (12) and the compressor wheel (14) via the rotor shaft (52). The rotor (54) is arranged axially between the turbine wheel (12) and the compressor wheel (14) on the rotor shaft (52). Roller bearings (60, 60) are arranged between the rotor (54) and the turbine wheel (12) on the one hand and between the rotor (54) and the compressor wheel (14) on the other hand. A single separate shaft bearing cassette (40) with a cassette frame (71) supports the two roller bearings (60, 60).
