  1. Bruno Barbosa Hector Cintron Glenn Drzewicki Advisor: Professor Yiding Cao SENIOR Design ProjectDepartment of mechanical EngineeringFlorida international universityA New Heat Engine and its Applications in Renewable Energy

  2. Problem Statement • The main objectives is to design a new type of heat engine based from the current structure of an internal combustion. • Various components for the new heat engine will be designed: • valves for the heating chamber • heating chamber shape and size • compact heating elements • various parts for timing management of the engine. • The new heat engine will be tested for performance, in terms of power output and thermal efficiency.

  3. Metrics • Power output : 8- 15 kW (10 – 20 hp) • Thermal Efficiency: 30-40% • Compression Ratio: 6:1 The compression ratio will be decreased from 9.4:1 into the desired range of 5:1 to6:1

  4. Initial Design Concept

  5. Proposed Design • The production of the final heat engine will be on the foundation of a Wankel rotary engine. • A Wankel rotary engine works on the same mechanical four stroke operation as a conventional piston engine.

  6. Work Cycle of Heat Engine

  7. Valve System

  8. Heating Chamber- Initial Concept • Initial Concept included small vortex generator to tumble airflow • Heating chamber resembled a pipeline • 2 heating chambers per rotor housing • 2 pathways for valve shaft

  9. Heat Chamber: Working Concept • Chamber requirements: • Mount to engine block • Withstand high pressure & temperature • Multi piece for maintenance • Tumble / swirl airflow

  10. Heat Chamber: Working Concept

  11. Project and Division Tasks • Bruno Barbosa: • Report Development • Piping, tubing, valves, etc. for system configuration • Heat exchanger & heating chamber design and analysis • Hector Cintron: • Report Development • Heat exchanger & heating chamber design and analysis • Valve design • Glenn Drzewicki: • Report Development • Fabrication/ manufacturing of engine components • Gear/ valve timing management & design

  12. Conclusion • The main goal of this project includes creating a heat engine with no Carbon Dioxide emissions and to show its application in renewable energy • The next IAB presentation in April will include: • Analytical Analysis and Structural Design • Major Components • Structural Design • Cost Analysis • Prototype System Description • Tests Results of Prototype
