ディーゼル微粒子フィルタの能動的な再生を制御する方法およびシステム

摘要

The method involves determining a set point temperature of gas, and determining a temperature request for controlling the temperature. A stationary gain is defined as ratio between a stationary value of a variation and a stationary value of a hydrocarbon mass flow rate variation. A control law for a hydrocarbon flow rate is defined at an inlet of an oxidation catalyst (15) through ratio of temperature demand and a corrected gain. The hydrocarbon flow rate is modified by applying the control law. An independent claim is also included for an internal-combustion engine comprising an exhaust gas treatment system.
