Class Information
Number: 60/277
Name: Power plants > Internal combustion engine with treatment or handling of exhaust gas > Having sensor or indicator of malfunction, unsafeness, or disarray of treater (e.g., fusible link, etc.)
Description: Apparatus, with means (1) that prevents operation if a necessary state or condition is not sensed or indicated (2) that stops operation if a malfunction or dangerous condition is sensed (3) that takes protective action to protect a system element responsive to a sensed malfunction or dangerous condition (4) or that acts to inform the operator of a dangerous state or malfunction.
