Analysis of Tested Waveform
As described above, the power balance test
measures the efficiency of each cylinder relative
to the total efficiency of the engine. KES-200
disables each of the cylinders, and then
measures the speed drop related to the
disabled cylinder.
If each cylinder of the tested engine contributes
an equal power, the bar graph will be uniform,
which indicates the difference of the percent
speed drop of each cylinder is small. Therefore,
we can make the following judgments from the
tested bar graph:
z The cylinder with a smaller percent speed
drop contributes less power;
z If the percent speed drop of a cylinder is
zero, the cylinder is misfire;
z If the speed increases while two or more
cylinders are disabled, it necessary to
check the ignition timing and the
secondary high-tension cable.
