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 to 6:1

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
