Abstract (en)
[origin: FR2862705A1] System for regeneration of exhaust gas cleaning assembly with catalyst and particle filter, integrated into exhaust pipe from an automobile diesel motor with turbocharger. The motor has a fuel injection with at least one post-injection and activated as an isocouple, by modifying control parameters of motor functions with at least two regeneration strategies of first and second levels, to achieve different temperature levels within exhaust pipe. The system is for the regeneration of the exhaust gas cleaning assembly (1) with a catalyst (4) and particle filter (5), integrated into the exhaust pipe (2) from an automobile diesel motor (3) with a turbocharger. The motor has a fuel injection (6) with at least one post-injection and activated as an isocouple, by modifying the control parameters of the motor functions with at least two regeneration strategies of first and second levels (8,9), to achieve different temperature levels within the exhaust pipe. The temperature level for the second strategy is higher than for the first. The control (7) and injection system give a temporary interlock for the second level strategy with an over-calibration (10) to raise and accelerate the temperature rise in the exhaust pipe and/or regenerate the particle filter.
