Method for heating component of exhaust gas after-treatment device of internal combustion engine, involves converting oxygen and fuel contained in exhaust gas to increase temperature of component of exhaust gas after-treatment device

摘要

The method involves converting oxygen and fuel contained in the exhaust gas to increase the temperature of the component of an exhaust gas after-treatment device. The opening time of the outlet valves of cylinders (3) of the internal combustion engine is adjusted such that the outlet valve does not open during the overlapping phase unlike as in the normal operation of the internal combustion engine.
