  "textContent": "For the injection of fuel into an internal combustion motor (12), and especially a diesel motor, a set volume of fuel is injected into the cylinder during the regeneration phase of the exhaust gas (G) processing system (16) and during the motor brake phase, and after the gas has been compressed in the cylinder. At least a portion of the fuel is burned in an oxidizing catalyst (20), between the motor and the exhaust processing system, to maintain or add to the exhaust gas temperature downstream of the catalyst. The set volume of injected fuel is determined at least partially by the function point of the motor and the characteristics of the catalyst e.g. the catalyst temperature during fuel combustion and the thermal efficiency of the catalyst. The start of the injection of the set fuel volume is dephased by at least 30 degrees of the crankshaft rotation angle, after the piston has passed through the top dead center point. The injection of fuel ends before the closure of the final exhaust valve. During the regeneration phase, an additional heater is activated e.g. an electrical resistance heater, to raise the catalyst temperature as long as it is too low to ignite the fed fuel portion. The exhaust gas processing system includes a granule filter and a nitrogen oxide trap.",
