A system for converting heat from an engine into work includes a boiler coupled to a heat source for transferring heat to a working fluid, a turbine that transforms the heat into work, a condenser that transforms the working fluid into liquid, a recuperator with one flow path that routes working fluid from the turbine to the condenser, and another flow path that routes liquid working fluid from the condenser to the boiler, the recuperator being configured to transfer heat to the liquid working fluid, and a bypass valve in parallel with the second flow path. The bypass valve is movable between a closed position, permitting flow through the second flow path and an opened position, under high engine load conditions, bypassing the second flow path.

What is claimed is: 1. A waste heat recovery system containing a working fluid for converting waste heat from a waste heat source of an engine into usable work while maintaining a temperature of the waste heat below a predetermined maximum value, the system including:a recuperator configured to add heat to a low pressure side of a Rankine cycle including a heat conversion device, a condenser, a pump, and a boiler, said recuperator receiving working fluid gas flowing to the condenser and working fluid liquid from the condenser to transfer heat from the gas to the liquid;means for bypassing the recuperator when the engine is operating under high engine load conditions to maintain the waste heat temperature below the predetermined maximum value; andmeans for controlling the bypassing means in response to an output from means for sensing the high engine load conditions.
