The cylinder spark plug opening clearances shall be the same in order to guarantee the
same ignition energy of each cylinder.
Tips:
In order to ensure the normal operation of the engine, spark plugs must be regularly
replaced with the standard ones from the original manufacturer as per the maintenance
manual, or poor acceleration, unstable idle speed, inaccurate ignition timing, irregular
flameout, increased electromagnetic interference and other unforeseeable faults may be
caused.
Four. High voltage cable (spark plug wire lead)
High-energy and high-voltage ignition is adopted for the system. The high-voltage cable
shall be equipped with proper impedance, capable of voltage endurance and control the
emitted wireless interference electric wave during high-energy and high-voltage ignition.
High-voltage cable resistance:
First cylinder: 3.8k
Second cylinder: 3.2k
Third cylinder: 4.7k
Fourth cylinder: 5.2k
Tips:
• The high-voltage cable and the ignition coil shall be marked with the number of
cylinder. Fix according to the mark. The first cylinder is adjacent to the driving
belt;
• Do not carry out the spark-over test directly to the ground;
• Loosened fixing may lead to ignition coil or computer damage;
• Reinstallation of the high-voltage cable at liberty will result in faults of the
computer components, increased radiation and failure of the electronic
components.
