Besides serving the purpose of increasing the octane rating when needed, Inpulse provides excellent cooling effects on the Cylinder Head Temperature and Exhaust Gas Temperature. Within one minute of operation the Cylinder temperature decreased 20ºF and the exhaust temperature cooled instantly to 150ºF.
The graph below shows the aircraft on a steep climb (Manifold Pressure Decreasing) and the cowl flaps closed. The automatic mode senses the cylinder head temperature above 400ºF and triggers the ADI injectors.
