Engine operating method and engine system for improved load step acceptance
Operating an engine system includes feeding a flow of exhaust to a turbine in a turbocharger, receiving a load step request, and increasing a speed of rotation of the turbocharger based on an increase in a fueling rate initiated in response to the load step request. Operating the engine system furth...

| description | Operating an engine system includes feeding a flow of exhaust to a turbine in a turbocharger, receiving a load step request, and increasing a speed of rotation of the turbocharger based on an increase in a fueling rate initiated in response to the load step request. Operating the engine system further includes limiting dissipation of heat energy of the flow of exhaust to the turbine to hasten an increase in the speed of rotation of the turbocharger, and increasing dissipation of heat energy from the flow of exhaust after satisfaction of the load step request. Varying of the dissipation of heat energy can be achieved by displacing an insulating fluid in the exhaust manifold with a heat exchange fluid such as water and/or engine coolant. |
