Abstract
A thermal fuse is installed in the exhaust flow path in or from a diesel particulate filter (DPF) of a combustion engine. At a temperature corresponding to overheating, or imminent overheating, of the DPF, the thermal fuse is activated to generate a signal initiating steps to avoid overheating of the DPF, such as shutting down of the engine.
