Abstract: The invention relates generally to waste exhaust energy recovery and, in particular, a system or a retrofit kit for generating cavitation including a cantilevered bearing arrangement. The system may include a turbine wheel configured to drive an input shaft in response to exhaust energy. The input shaft may further support a cavitation impeller for generating pressure, fluid flow, and cavitation within a fluid. Upon collapsing, the cavitation bubbles may release energy that is captured by an output turbine mounted on an output shaft. Output shaft may harness the captured energy, which may be transmitted to an output device to, for example, turn a crankshaft to add torque or operate a generator to charge an external power source, such as a battery. Additionally, the system facilitates reducing emissions and fuel consumption while also supporting enhanced performance.
