An exhaust system has at least one exhaust tailpipe which is led through a rear apron of the motor vehicle. The drive train of the vehicle has a rear axle. An air duct is provided in a rear region, which air duct supplies exterior air to the at least one exhaust tailpipe at least in sections. The rear axle has at least one rear axle cover at least in sections. An air inlet opening of the air duct is arranged behind the rear axle cover in a travel direction of the motor vehicle. As a result of the design of the motor vehicle, the rear apron is protected from impingement by hot exhaust gases.

To ventilate a heat management system of an internal combustion engine, in which coolants circulate in several coolant circuits, connected inlets of a rotary valve may be opened and closed in a predetermined sequence, in order to ventilate one or more of the coolant circuits in the direction of the compensation tank, by means of at least one ventilation circuit which is in fluid connection with a coolant compensation tank. The rotary valve may be controlled by means of a control unit, wherein a non-connected inlet of the rotary valve is in fluid connection with the coolant compensation tank.

Method and device for ventilating a heat management system of an internal combustion engine

A heat management system for an internal combustion engine has an engine cooling circuit, a main cooling circuit that has a main cooler, a heating circuit that has a heating heat exchanger, a coolant pump that moves coolant through the circuits and a rotary slide valve that has at least one switched and at least one non-switched inlet, such that the heating return flow leads into a switchable inlet of the rotary slide valve.

A coupling component is provided for a plug-in connection for media-carrying lines, and includes a flow channel that has an inner cross-section that is enlarged in steps in order to allow the formation of a reflux zone when carrying the media, and a vent opening. The step-like enlargement is asymmetrically formed over the circumference of the inner cross-section so as to achieve an improved separation capacity.

Coupling for a plug-in connection

According to a method and a system for controlling a cooling system of an internal-combustion engine, the capacity of a coolant pump is controllable as a function of a fuel quantity fed to the internal-combustion engine.
