Abstract
The invention relates to a diesel internal combustion engine with an exhaust treatment device for the reduction of nitrogen oxides and with a fuel injection system comprising a high-pressure pump and at least one solenoid valve-controlled injection nozzle. The injection nozzle is actuated by an electronic control unit and is intended both for the primary injection, provided for the combustion, and for the additional injection, influencing the effectiveness of the exhaust treatment device. The fuel injection nozzle provided for the primary injection also provides for the secondary injection. The secondary injection takes place as a supplementary injection at the earliest in the region of the end phase of the combustion after the ignition top dead center.
