Product catalog summary
Overview of SPARCS* Cooling System
The SPARCS* cooling system is designed for Wankel Rotary Engines, utilizing self-pressurizing blow-by gases from the combustion process as a cooling medium. This system recirculates a pressurized air-gas mixture in a closed-loop circuit, driven by an internal fan connected to the main shaft. The mixture absorbs heat from the engine's rotor and releases it through an external heat exchanger.
Key Features
  • High Heat Removal Efficiency: The high density of the pressurized air-gas mixture allows for more effective heat removal compared to standard air cooling methods.
  • Sealed System: The completely sealed design eliminates oil loss to the atmosphere, a common issue in air-cooled rotary engines.
  • Reduced Oil Consumption: Oil is continuously recirculated within the cooling gas mixture, lubricating moving surfaces and reducing overall oil consumption.
Technological Innovation
The SPARCS* system is a patented, liquid-cooled technology that combines the simplicity of design with the high power-to-weight ratio of rotary engines. It addresses and mitigates the drawbacks of traditional cooling systems used in existing Wankel rotary engines, such as closed-loop, oil-cooled, or forced-air-cooled systems.
Conclusion
The SPARCS* cooling system represents a significant advancement in rotary engine technology, offering improved efficiency and reduced maintenance issues.
