The Revolution Inertia Engine Dynamometer, developed by Excelleration, LLC, provides engine builders and engine component manufacturers with a tool that provides data that directly correlates to on-track engine performance. Using the concept of inertia, the engine is allowed to accelerate at its natural rate. Then, the data is compared in terms of elapsed time when differentiating performance characteristics.

• User Adjustable Inertia Configuration for Representing Variety of Effective Inertia
   
• Alternative Gear Ratios for Adjustable Effective Inertia Representation at Crankshaft
   
• Engine Endurance Testing with Combined Inertia and Absorber Loading Capability
   
• Dynamometer Clutch Allows for Controlled Inertia Engagement and Rapid Disengagement
   
• Self-contained Dyno Lubricating System with Temperature Controlled Fluid
   
• Natural Acceleration Rate Measurements... NEITHER FORCED NOR FIXED
   
• Elapsed Time Repeatability Measured and Displayed to 0.001 seconds
   
• Smaller Magnitude Performance Enhancements are Measured
   
• Measured Repeatability less than 0.15% between consecutive sweeps
   
• Endurance Testing Capability following gathered on-track data (engine rpm trace, elapsed time, and throttle position imported from Microsoft Excel)
   
• Ability of the Dynamometer to Drive the Engine During Deceleration After
  Occurs During Actual Conditions
   
• Direct Coupling Methods – Not Reliant on a Viscous Coupling Technique
   
• Ability to Test Clockwise and Counter-clockwise Rotation Engines
   
• The Engine Controls the Dyno... The Dyno Does NOT Control the Engine...

“What Happens… Gets Measured!”

Because of the unique patented design of The Revolution Inertia Dynamometer, the vehicle mass that the engine will accelerate during racing conditions is represented by configuring the inertia and dynamometer gear ratio. The advantage of this feature is a close approximation of the load that the engine experiences during actual racing conditions.

• Vehicles weighing from approximately 1,200 lb up to 3,500 lb (depending on the tire size and the gear ratio of the vehicle) can be represented on one machine.
   
  
• Gear Ratios from 3:1 through 5:1 Available for Effective Inertia Configuration
