  • Method and arrangement for controlling the operation of a secondary air pump
    Patent number: 5319928
    Abstract: The emission of toxic materials when starting an internal combustion engine equipped with a catalytic converter and a secondary air pump can be further reduced with the method and arrangement of the invention. This reduction takes place by a switch-on of the secondary air pump under selectable conditions which include a warm start of the engine. The danger of overheating the catalytic converter by the operation of the secondary air pump for a warm engine is taken into account by a variable switch-on duration of the secondary air pump which can be realized by a counting procedure having an increment dependent on operating parameters.
