A side channel compressor for compressing gas includes a housing, which forms a side channel, and an impeller drive arranged in the housing. The housing forms a feed channel fluidically connected to the side channel for feeding gas to the side channel and a discharge channel for discharging gas out of the side channel that is fluidically connected to the side channel. The feed channel branches into two separate channel arms each extending along a channel arm center axis. The housing is subdivided along a separating plane into first and second housing parts which sealingly lie against one another. The discharge channel is passed through between the two channel arms and either a first or second discharge channel part of the discharge channel, opens out on a connecting surface of the first or second housing part forming a gas outlet opening arranged apart from the separating plane.

Side channel compressor for compressing gas

An internal combustion engine for a motor vehicle includes a crankcase ventilation device for removing blow-by gas from a crankcase, a pressure sensor being provided for measuring the gas pressure in said crankcase, and a control unit connected to and in communication with the crankcase ventilation device being configured and/or programmed to run a tightness test for said crankcase ventilation device when the internal combustion engine is switched off.

Internal combustion engine for a motor vehicle

A fresh air supply device for an internal combustion engine may include a housing and a flap arrangement arranged in the housing. The flap arrangement may include at least one flap for controlling a fresh air flow through a fresh air path to a respective cylinder of the internal combustion engine. The flap arrangement may include a common actuator shaft connected to the at least one flap in a torque-proof manner and mounted rotatably about an axis of rotation in a plurality of bearings of the flap arrangement. The actuator shaft may have at least one actuator shaft section in which the actuator shaft has a right-angle bend configured to interact with a stop present on the housing for limiting rotational movement of the actuator shaft.
