ABSTRACT:
A system for protecting the catalytic exhaust gas combustion devices of an automotive engine featuring two sets of cylinders, which system has, for each set of cylinders: a first sensor housed in the exhaust pipe downstream from the catalytic combustion device and designed to supply a first signal as a function of the temperature of the combustion device; a comparing block for supplying a second signal in response to the first signal reaching a threshold value indicating a predetermined temperature of the combustion device; and a central processing unit of an electronic fuel injection system, designed to cut off a fuel supply to the injectors of the aforementioned set of cylinders as a function of the aforementioned second signal.
