Methods and apparatus for controlling an engine having a first maximum power rating based on at least a first predetermined operating condition of the engine. A first sensor transmits a first signal as a function of the engine operating at a predetermined operating condition other than the first predetermined operating condition. A control device receives the first signal and transmits a power signal to the engine as a function of the first signal. The power signal may, by itself, or in conjunction with other signals, cause the engine to produce a quantity of power in excess of the first maximum power rating.

Method and apparatus for controlling an engine

An internal combustion engine includes at least one combustion cylinder and a turbocharger with a compressor for a combustion fluid which is introduced into the combustion cylinder. The compressor has a discharge outlet. An air duct is connected with the combustion cylinder for providing the combustion fluid to the combustion cylinder. The air duct has an inlet opening. An air pipe interconnects the compressor with the air duct. The air pipe has a first end connected with the discharge outlet of the compressor and a second end connected with the inlet opening of the air duct. The second end includes an outwardly projecting shoulder. A flange disposed around the second end of the air pipe includes a recess capturing the shoulder therein and an axial face attached directly with the air duct.
