Existing Wankel rotary engines available on the market typically use either closed-loop, oil-cooled or forced-air-cooled
systems. AIE’s innovative SPARCS cooling system combines simplicity of design with the inherent high power-to-weight
advantage of rotary engines, while practically eliminating the drawbacks these systems had in the past

Compact SPARCS is integrating an intercooler, or heat exchanger within the rotor housing. As with SPARCS, the
re-circulating oil-gas mixture passes through the engine’s rotor, absorbing heat before being ducted through the
integrated heat exchanger, which rejects heat into the engine’s rotor housing and ultimately to the engine’s main liquid
cooling system.

Wankel Rotary engines have many advantages over reciprocating engines and these advantages can be further
enhanced with the use of AIE’s patented exhaust expander technology (CREEV), reducing overall exhaust emissions and
increasing thermal efficiency by up to 20%.
