Abstract
The method for turbocharging an engine of a locomotive in which the engine is operable at a plurality of discrete operating power levels includes controlling at least one of energy to a motor-assisted turbocharger at a plurality of discrete energy levels and air pressure from the motor-assisted turbocharger to the engine at a plurality of discrete air pressure levels above ambient air pressure based on at least some of the plurality of discrete operating power levels (e.g., low power levels) of the engine. Desirably, the method also includes controlling generation of electrical energy from the motor-assisted turbocharger at some of the plurality of discrete operating power levels (e.g., high power levels) of the engine. Apparatus for turbocharging a diesel engine of a locomotive incorporating the above methods are also disclosed.
