Process for controlling an internal combustion engine, especially with lean operation, to achieve pre-determined nitrogen oxide emission values comprises controlling the lambda value of a fuel/air mixture to be burnt in the engine or a substitute engine pa...

Process for controlling an internal combustion engine, especially with lean operation, to achieve pre-determined nitrogen oxide emission values comprises determining, preferably directly, the actual value of the lambda value or the calorific value of a fue...

The method involves measuring the actual power of the engine and the temperature in the cylinder (4) or in the exhaust tract (38) and reducing the desired power in the event of a power break-in of the actual power and then temporarily interrupting the fuel...

The internal combustion engine has at least one cylinder in which a fuel-air mixture can be compressed by a piston. The temperature of the mixture in the combustion chamber can be brought to at least above 80 percent and at the most 98 per cent of the self...
