VID Role in view of mechanical disequilibrium between cylinders |
| |
|
| |
As per each cylinder, combustion efficiency is different mechanically.
In case of single combustion chamber, the changing cycle of internal pressure
within one chamber is main factor to describe piston movement, crank angle
variation.
However, in case of multiple cylinders, it is practically impossible for
each combustion chamber to have exactly same burning platform from induction
to exhaustion. Though the same air and fuel are inducted, combustion efficiency
deviation is existent such as piston & piston ring, lubrication oil,
the carbon sludge inside chamber, abrasiveness or friction nature, valve
tightness as well as l oil or heat leakage per cylinders. This kind of mechanical
disequilibrium as COV index (Combustion Variation) has been also measured
and described as graphs.

Figure (E) graph displays the disequilibrium of Maximum pressure (Pmax)
per combustion chamber. It is common sense that the mechanically uneven
pressure hinders the fine reciprocating motion of piston to crankshaft,
creating mechanical vibration as well as noise and harsh sound, leading
to the torque reduction. What VID does is calculating the resonance deviation
per cylinder and generating the corresponding input frequency matched to
each cylinder’s requirement to make mechanical equilibrium as a whole. Accordingly,
differently adjusted frequencies are penetrating to each chamber. By doing
this, ultimately minimizing the deviation among cylinders can be fulfilled.
From figure (E) and figure (F), we can see VID’s resonance
effect onto the combustion chamber is preventing any possible energy leakage
of momentum like vibration, noise and wrench and increasing the torque
by finding out the optimal moment of expansion timing.
