OPERATION

Variable Compression Ratio and Charge

Operation of the prime mover system 

COMPONENTS

  1. Control piston
  2. Initial burn volume (IBV)
            Alters to change CR
            Volume; IBV to 0 to IBV
  3. Spark plug
  4. Fuel injector
  5. Main chamber
  6. Power Piston
  7. Intake passage (from pump)
  8. Exhaust passage

VCRC™ SOLUTION

I. Initial compression
       Air only
            i. control piston moves to set point
            ii. Volume moves from 0 to IBV

II. Final Compression
        @ 90° BTDC, fuel injected
             Fuel mixes with air stream

III. Initial combustion in IBV

iV. Secondary burn in MC
         > 30% lean
         HC and CO oxodozed

V. Expansion
        Power flows to shaft in III and IV
        IBV moves to 0 volume

VI. Scavenge
         Air quality regulated
              Exhaust temperature > 200

Where others stop and say, “It won’t work.” we are just beginning.

We continue to analyze the complete system and find the solution to make it work.
