Single-spark ignition coils

With systems with single-spark ignition coils ,one ignition coil with primary and secondary winding is assigned to each cylinder.These ignition coils are usually installed directly at the cylinder head above the spark plug.

These coils are also connected with the primary winding at terminal 15 (voltage supply
plus) and at terminal 1 (ground) with the control unit. The secondary winding is connected with the output of terminal 4 to the spark plug .If a terminal 4b should be present , this connection is used to monitor misfiring .Triggering is in the sequence specified
by the control unit .

A single-spark coil's circuit corresponds to that of a conventional ignition coil . In addition, a high-voltage diode is used in the secondary circuit to suppress the so-called closing spark .The undesired spark produced when the primary winding is switched on through selfinduction in the secondary winding is suppressed by this diode. This is possible since the secondary voltage of the closing spark has opposite polarity to the ignition spark. The diode blocks in this direction .

With single-spark coils the second output of the secondary winding is routed to ground
through terminal 4b . A measuring resistor is installed in the ground cable to monitor
ignition, this represents the drop in voltage caused by the ignition current during sparkover as a measured parameter for the control unit.

Possible reasons for failure

Internal short-circuits

Overheating of the coil caused by the ageing process, a faulty ignition module or a faulty
output stage in the control unit.

Fault in the control voltage

The coil charging time increases on account of the voltage supply being too low, this
can lead to premature wear or excess load on the ignition control unit or the output
stages in the control unit.
This can be caused by a faulty cable or weak battery.

Mechanical damage

Damage to the ignition cables through marten bites.
A faulty valve cover seal and escaping motor oil can damage the insulation of plug slot
coils.
Both causes lead to sparkover and thus to premature wear.

Contact fault

Contact resistance in the wiring due to humidity penetrating in the primary and secondary area,also frequently caused by engine washing or the use of grit in winter.

Faults can become noticeable as follows
 Engine does not start
 Vehicle misfires
 Poor acceleration or loss of power
 Engine control unit switches to safe-home mode
 Engine warning lamp lights up
 Fault code is stored

Attentions when install the ignition coil      

1. Vehicle voltage shall be around 12V~13.5V

2. Engine must flameout when replace the ignition coil

3. Check the carbon deposition of the spark plug, better both replace the ignition coil and the spark plug.

4. Check the situation of the high voltage cable, electric leakage is not allowed.

5. The coil plug shall be firmly connected, won’t get loose or drop off.

6. The high voltage plug of the coil shall be connected to the spark plug on the cylinder cover of  the engine.
