A device for exhaust-gas purification utilizes reduction of nitrogen oxides which are present in the exhaust gas from internal combustion engines by way of gaseous ammonia with an SCR catalytic converter. The functions of the device are monitored with regard to their line paths with connections, valves and sensors by referring to these elements themselves using suitable control circuitry via the evaluation and control unit.

Device for exhaust-gas purification, and an operating and monitoring for said device

A device with a starter-generator for internal combustion engines, the combustion engine having a centrifugal mass for stabilizing its smoothness of running, with at least one first nonpositive clutch and a flywheel generator, which can be actuated by means of an electrical energy source and is in effective connection with a selectable gearbox, the nonpositive clutch being provided between the flywheel generator, which can be actuated by means of an electrical energy source, and the combustion engine, and the flywheel generator forming the centrifugal mass of the combustion engine.
