摘要

A CATALYTIC CONVERTER (7) FOR CLEANING EXHAUST GAS, PARTICULARLY FROM A SMALL ENGINE, INCLUDES A CONVERTER HOUSING (6) AND AT LEAST ONE HONEYCOMB BODY (12) DISPOSED THEREIN AND CONTAINING LAYERS OF SHEET METAL (19) HAVING CATALYTICALLY ACTIVE MATERIAL. THE CONVERTER IS DISPOSED ON A DIVIDING WALL (5) OF A MUFFLER HOUSING (1) FOR A SMALL ENGINE. THE DIVIDING WALL (5) HAS AT LEAST ONE OPENING (9). THE HOUSING (6) HAS AN UPPER HOUSING COMPONENT (3) AND A LOWER HOUSING COMPONENT (2). THE CONVERTER HOUSING (6) IS SHAPED IN SUCH A WAY THAT EXHAUST GAS CAN FLOW SUCCESSIVELY THROUGH THE HONEYCOMB BODY (12) AND THE OPENING (9) AND THE CONVERTER HOUSING (6) IS SPACED APART FROM THE MUFFLER HOUSING (1). SUCH A CONVERTER CAN BE MANUFACTURED COST-EFFECTIVELY, CAN EASILY BE INTEGRATED INTO EXISTING STRUCTURES AND DOES NOT LEAD TO UNACCEPTABLE TEMPERATURES OF THE OUTER WALL OF THE MUFFLER HOUSING (1) DURING OPERATION.(FIGURE 8)
