Improved Piston Dynamics

Piston acceleration and deceleration rates are dramatically reduced providing increased “dwell” time for extraction of combustion energy and reduced stress and friction.

Plot of Efficient-V piston travel compared to a Ford 302:

  • X axis represents crankshaft angle, Y axis is piston travel in the cylinder
  • Efficient-V piston travels slower around TDC
  • Combustion forces act on the piston longer
  • Thereby extracting more energy from the fuel
