A method of regulating an internal combustion engine, in particular involving a lean-burn mode of operation, for achieving predeterminable nitrogen oxide emission values from the internal combustion engine, wherein the actual value of the &#x3bb;-value or the calorific value of a fuel-air mixture to be burnt in the internal combustion engine or a nitrogen oxide emission value is detected, preferably directly measured, and is regulated in dependence on a parameter which is characteristic of quality and/or quantity of the fuel supplied or in dependence on the power (P) delivered by the internal combustion engine.

Method of regulating an internal combustion engine

A method of regulating an internal combustion engine, in particular involving a lean-burn mode of operation, for achieving predeterminable nitrogen oxide emission values from the internal combustion engine, wherein the &#x3bb;-value of a fuel-air mixture to be burnt in the internal combustion engine or an equivalent engine parameter in a defined relationship with said &#x3bb;-value is regulated in dependence on the amount of fuel supplied per unit of time or in dependence on the fuel energy supplied per unit of time (Q).

An arrangement for regulating a spark-ignition internal combustion engine, in particular a stationary boosted gas Otto-cycle engine, comprising a power regulating device acting on at least one power setting member, wherein an ignition time regulating device ( ) adjusts the ignition time (ZZP) in dependence on the position of the power setting member ( ).

Arrangement for regulating a spark-ignition internal combustion engine

Apparatus for regulating an engine parameter, in particular the output power or the speed of rotation of an internal combustion engine, wherein there are provided two or more adjustable devices by way of which the engine parameter to be regulated can be influenced. There are provided two or more separate regulators, each of which regulates a respective one of the adjustable devices in dependence on the detected actual value of the engine parameter and a predeterminable reference value. There is also provided a change-over switching device by way of which selectively one of the regulators can be activated for regulating the adjustable device associated therewith.
