The engine also includes a turbocharging system configured to pressurize ambient airflow for delivery to the cylinder. The turbocharging system includes a low-flow turbocharger, a high-flow turbocharger, and a flow control device for selectively directing post-combustion gas to the low-flow and high-flow turbochargers. A controller directs the post-combustion gas to the low-flow turbocharger and selects a first predetermined exhaust valve timing when the engine operates below a predetermined speed and above a predetermined load. Alternatively, the controller directs the post-combustion gas to the high-flow turbocharger and selects a second predetermined exhaust valve timing at or above the predetermined engine speed. The first predetermined exhaust valve timing traps less post-combustion gas in the cylinder as compared to the second predetermined exhaust valve timing.

Embodiments of a system that configured as a closed loop system, with a pump, an evaporator, a power generator, and a condenser, the combination of which circulate a working fluid to generate electrical power. The embodiments can harvest residual energy in the working fluid to improve efficiency and to reduce power loss that can derive from the pump as well as other auxiliary loads (e.g., fans). In one embodiment, the system incorporates members that operate in response to the working fluid, often in the higher pressure vapor form that occurs after evaporation and/or power generation stages. These members can include mechanical elements, for example, that have motive action (e.g., reciprocate, rotate, etc.) that is useful to satisfy operating and power requirements of auxiliary loads. For the pressurization stage, these mechanical elements may embody a piston-and-cylinder arrangement (or other rotary or linear positive displacement arrangement) that generates motion that can drive the pump.

A water/steam cycle includes a steam generator, a steam turbine, a water cooled condenser and a feedwater pump. The condenser includes within a condenser shell at least one tube bundle with an internal air cooler, which is connected to an external ejector/vacuum pump by means of a suction line. In order to reduce the condenser evacuation time at the start-up of the water/steam cycle without using auxiliary steam, an additional evacuation line with a motorized isolating valve connects the external ejector/vacuum pump with the condenser shell. The action of the isolating valve is controlled by means of a control.
