A catalyst according to the invention with its cooling package is an easily exchangeable unit that is plugged into an existing silencing device. The catalyst (29) is integrated with a perforated radiation protection and distribution plate (26) in front of it and furthermore with another plate behind it functioning as a lid (24) and fastening member against a silencer. Outside the lid there is a cooler attached which removes the heat. A waste gas outlet (32) takes place via a waste gas tube (23) to the rear corner of the silencer, where fan air, used for engine cooling, passes by. The waste gases get mixed to the fan air and the temperature will be reduced to an acceptable level. |
