Definitions
- This period can be determined from a further look up table, for example calibrated upon development of the system or can be determined using a feed- back approach such as a PID (proportional/integral/derivative) control algorithm as a result of which the metering of fuel injection will be rapidly tailored to converge the temperature rate with the desired value.
- the amount of fuel injection may be reduced for situations where the engine speed and load are high, thereby preventing unwanted pass through of fuel.
- table 1 may vary in an additional dimension with engine speed and/or load.
- the system continues to measure Tco and in block 302 monitors to establish whether the measured T C o has met the next set point (in the first instance 270°C from Table I).
- FIG. 6 A further improvement is shown in figure 6 whereby an electrical heater 60 is located immediately before the front face 18 of the catalytic converter 18.
- the main method of heat transfer from the heater 60 to the catalytic converter 18 is via radiation. This is more efficient than using the exhaust gas to transfer heat via convection, as a large amount of power is required to get significant temperature rise of the exhaust gas.
- the invention can be applied to any appropriate engine or fuel type and that fuel injection can take place in any appropriate part of the exhaust stream.
- the approaches as described above can be described to any appropriate temperature dependent exhaust treatment regime or other temperature raising mechanisms which rely on fuel injection.
- the fuel injection can be metered by adjusting fuel alignment, fuel injection rate or fuel injection pulse duration, fuel injection pressure variation or fuel type variation.
- control can be implemented using appropriate sensed parameters of operation of the engine and the exhaust stream components and using any appropriate sensors and injectors.

Abstract
L'invention concerne un régime de régénération d'échappement dans lequel on régénère un filtre (20) en déclenchant une réaction exothermique dans le filtre (20) afin de brûler une charge particulaire. Pour atteindre les températures de régénération appropriées, un combustible est injecté dans le flux d'échappement et s'oxyde au contact d'un convertisseur catalytique (18). Le régime de commande comprend l'étape consistant à mesurer l'injection de combustible en fonction de la température du flux d'échappement pour obtenir un régime de commande souple, indépendant du cycle d'utilisation du moteur.
