Process and apparatus for reducing warm-up emissions of a direct injection internal combustion engine |
摘要 |
A method and an arrangement are provided for reducing warm-up emissions in the exhaust system of a direct-injection internal-combustion engine. The method includes the steps of adjusting a lean air/fuel mixture for the engine-related combustion; implementing a late injection into the exhaust gas during the exhaust cycle of the internal-combustion engine, so that the exhaust gas contains an essentially stoichiometric air/fuel mixture; and igniting the stoichiometric air/fuel mixture contained in the exhaust gas in the proximity of a catalyst device for heating up the catalyst device.
