mainly used to:
a.
Analyze the ignition close angle of single
cylinder.
b.
Analyze the capability of ignition coil and
primary high tension circuit.
c.
Find the improper mix-gas A/F ratio of single
cylinder.
d.
Analyze the capability of capacitance.
e.
Find the spark plug that causes the misfire
of cylinder.

Raster Pattern
Fig. 3-22
Fig 3-22 shows the raster pattern. With the raster
pattern, it is very convenient to analyze the close
angle and opening angle of each cylinder and the
working state of each cylinder spark plug.
Parade Pattern
Fig 3-23 shows the parade pattern. This test can
provide the valuable information about
combustion quality state of each casing.
