Method for controlling the fuel supply for an internal combustion engine with a heatable catalytic converter |
摘要 |
An internal combustion engine is equipped with a lambda regulating device, a catalytic converter disposed in an exhaust pipe of the internal combustion engine, a device for externally heating the catalytic converter to its operating temperature, and a secondary-air pump which injects additional air into the exhaust pipe. A method for controlling the fuel supply for the internal combustion engine includes injecting an additional fuel quantity during operation of a burner and during secondary-air injection, for heating the catalytic converter, as a function of engine air mass flow and an additional secondary-air quantity which is injected into the exhaust system.
