Advisor: Professor Yiding Cao
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.
Metrics
Power output : 8- 15 kW (10 – 20 hp)
Thermal Efficiency: 30-40%
Compression Ratio: 6:1The compression ratio will be decreased from 9.4:1 into the desired range of 5:1 to 6:1
Initial Design Concept
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.
Work Cycle of Heat Engine
Valve System
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
Heat Chamber: Working Concept
Chamber requirements:
• Mount to engine block
• Withstand high pressure & temperature
• Multi piece for maintenance
• Tumble / swirl airflow
Heat Chamber: Working Concept
