the same. Each cylinder pattern should be roughly the same. However, the actual
situation is not ideal, graphics assembly will be large or small jitter，such as ignition
or breakdown voltage fluctuated，combustion times may vary in length，these do not
necessarily indicate the engine failure. These may need us have experience
cumulation by time, combined with a comprehensive analysis of other graphics，but it
can be said, the ideal graphics may not been seen.
Ignition or breakdown voltage：If the ignition voltage is too high, even more than
the range of the screen, indicating that the resistance value is too high in secondary
ignition circuit. Open line，spark plug damaged，high-voltage or spark plug gap is too
large may have resulted in the phenomenon of high breakdown voltage，Conversely,
if the breakdown voltage is too low，It indicates that the resistance value in ignition
secondary circuit is lower than normal ， spark plugs may be dirty or rupture,
high-voltage leakage and other reasons caused.
Combustion line and combustion time：if combustion line has too much clutter，
It represents cylinder misfire. Or due to premature ignition, injectors damaged, spark
plugs dirt and other reasons. The length of the combustion line duration is related to
mixed gas concentration in the cylinder. Typically, it means that the combustion time
exceeding 2ms gas mixture is too thick. Conversely, if combustion time is less than
0.75ms indicates too lean mixture.
8）Correct broken-line by broken wire needle.（all need to break the wire for
measurements except for secondary ignition）
