HC-CARGO Ignition Coils

Engine Management: Heavily enhanced range of Ignition Coils

As earlier communicated we are developing an attractive, reliable and competitive range of most commonly replaced sensors, coils and valves. First type are ignition coils!

Ignition coils have undergone a complete redesign in recent years. Traditional oil/ asphalt filled, barrel-shaped coils belong to the past. Today, most manufacturers use resin-filled plastic coils with iron cores that are manufactured in all shapes and sizes.

 

Fundamentals

  • Ignition coils are transformers that are able to provide high voltage pulses using the principle of magnetic induction.
  • Ignition coils can convert a vehicle’s 12 volt power supply to the 25-30,000 volts required to jump the gap of the spark plug, thus instigating combustion.
  • Most modern cars are equipped with several single pencil coils or a “rack” of pencil coils.
  • Used in petrol-driven cars

Purpose

  • The purpose of the coil’s pulses is to generate a spark (arc) between the electrodes of the spark plugs that is necessary to start the internal combustion.

Ignition coil function

  • There are two separate coils inside all types of ignition coils: a primary coil and a secondary coil.
  • Ignition coils feature a laminated magnetic core. Both the primary and secondary coil are wrapped around this core.
  • The primary coil receives voltage from the battery leading to a magnetic field around the primary coil.
  • When the voltage flow is interrupted, the magnetic field collapses and generates a voltage pulse in the secondary coil.
  • This high-voltage pulse will then generate a spark (arc) between the electrodes of the spark plugs on the internal combustion engine.
  • The spark must be of sufficient intensity and duration to start the internal combustion of the air-fuel mixture successfully. 
Troubleshooting

Troubleshooting

Occurring errors

  •      The engine warning light is on
  •      An error code is stored, e.g. "P0351 ignition coil" A "primary / secondary malfunction circuit".
  •      Startup problems or no ignition at all
  •      Reduced acceleration and engine power
  •      Increased fuel consumption


Possible causes of a faulty ignition coil

  •      Mechanical damage
  •      Internal short circuits.
  •      Contact Error
  •      Power supply failure due to e.g. low battery level


Can you drive on with a faulty ignition coil?

  •      It's possible, but not recommended - especially due to consequential damage.
  •      If there is no ignition at all: Driving is not possible.
