Abstract

A diesel- particulate- filter device and a selective- catalytic- reduction device are supported by a vehicle frame. A connecting pipe has in at least part of said connecting pipe, a bellows section that can extend and contract. Said connecting pipe connects an engine and the diesel- particulate- filter device to each other. The bellows section is angled downwards away from the engine.
