An exhaust system has an exhaust tailpipe cover provided in an outlet region and, on the inside, contains inner exhaust pipes which are disposed spaced apart from the exhaust tailpipe cover by a passage. The passage in the exhaust tailpipe cover results in the exhaust tailpipe cover being exposed to as little thermal loading as possible and avoids transmitting heat to a surrounding vehicle rear part, in particular made of plastic.

Exhaust system

A device for precluding induction of impurities with raw air inducted into an internal combustion engine, wherein at least one air intake stub of an air filter container draws air from an air accumulation chamber which is sealed off on the front side by a front end covering and on the back side by a convex separating partition adjacent to the engine chamber, and which contains at least one air intake opening located in the floor area of the partition which communicates with air intake openings in the front end of the motor vehicle.

Exhaust gas arrangement for a motor vehicle

In order to make an air filter housing usable for several types of engines, the air filter housing is provided with outlets branching off the cleaned-air chamber, in which case each outlet can optionally be closed off tightly according to the type of used engine.

Intake system

An air filter housing for an internal combustion engine, which includes an unfiltered air capsule and a filtered air capsule, contains an orifice with perforations which are covered by air-permeable fabric or a sound element. Airborne sound emission occurs through these orifices and through the fabric or the sound element in such a way as to optimize the exterior and interior sounds of the vehicle.

Air filter for an internal combustion engine

A connecting line is provided for removing water entering an air filter housing, between the air filter housing and a cooling unit. Due to the existing difference in pressure between the air filter housing and the cooling unit, water can be suctioned out of the air filter housing via the connecting line.

Device for guiding away water, dust and the like

The invention relates to an intake system for an internal-combustion engine having an air conduit, particularly an air pipe, whose end is captively and releasably fastened to an opening of a component of the internal-combustion engine. Receiving elements for fastening devices are provided at the opening of the component, which fastening devices reach through bearing sleeves fastened to the end of the air conduit.

Intake system for an internal-combustion engine

An intake system for an internal-combustion engine has an air line (air pipe) whose end is detachably fastened on a flange of a component. The flange of the component has at least one recess which, in the mounted condition of the connection, engages with fastening elements are provided on the air pipe, so that the air pipe is axially secured on the flange of the component.
