Method and apparatus for controlling an internal combustion engine

The regulation method detects the combustion chamber pressure within an engine cylinder (2) in dependence on the crank angle of the crankshaft (4) controlling the movement of the reciprocating piston (3), with derivation of a corresponding engine torque, combined with the angular velocity of the crankshaft for providing the effective engine torque, used for regulation of at least one operating parameter of the engine (1). An Independent claim for a regulating device for a diesel engine is also included.
