Waste heat recovery in automotive vehicles is a method to extract energy as work that would otherwise be wasted through engine exhaust. The goal of this research is to model the Rankine power cycle in heavy-duty diesel powertrain and develop advanced control algorithms for optimal power generation and improved vehicle engine efficiency.

Currently, prototypes from automotive companies have demonstrated potential additional power output under certain test driving conditions. However, a major challenge of the waste heat recovery system is its performance can vary considerably under a range of actual driving conditions, to a point of little to no power recovered and possible damage to the system and vehicle. Model-based estimation techniques investigated to predict and monitor performance of the vehicle while advanced control strategies ensure optimal operation of the waste recovery system under a variety of driving loads.
