Abstract

A system having an engine is provided. The system includes a high pressure (HP) turbocharger and a low pressure (LP) turbocharger connected in series with each other. The system also includes a first valve assembly configured to selectively bypass at least a portion of the exhaust from the engine to the LP turbocharger. The system also includes a storage tank configured to store a pressurized fluid and configured to be in fluid communication with the HP turbocharger and the LP turbocharger. The system further includes a second valve assembly in fluid communication with the storage tank, the HP turbocharger and the LP turbocharger. The system also includes a controller operatively coupled to the first valve assembly and the second valve assembly. The controller is configured to selectively operate the first valve assembly and the second valve assembly based on a change in a load requirement on the engine.
