Figure (E) and (F) these graphs contain two meaning ;

1.Under Resonance Platform, engine show the straight Line up as P(max) increase versus P(intake) increase while base-engine show the dull slope at low and high intake pressure range.

2.Under Resonance Platform, each cylinder’s combustion variation is meaningfully equilibrium while base-engine’s combustion deviation is highly sharp as significant changing per cylinders.

This test proves that VID can
achieve the mechanical equilibrium per cylinders,
leading to better combustion efficiency.
