Heavily enhanced portfolio of ignition coils

HC-CARGO Engine management: Heavily enhanced Ignition Coil portfolio

Engine management systems have become a fundamental element in modern motor vehicles. The number of different electronic and electric components in vehicles has dramatically increased in recent years.

Therefore, HC-CARGO is developing an attractive, reliable and competitive range of most commonly replaced sensors. The first step is to offer you an expanded and updated ignition coils program.

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. 

Did you know?

  • 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.

 

 

 

 

 

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.  

Occurring faults

  • The engine warning light illuminates.
  • A fault code is stored, e.g. “P0351 Ignition Coil "A" Circuit Primary/ Secondary Malfunction”. 
  • Starting difficulties or no ignition at all
  • Reduced acceleration and engine power
  • Increased fuel consumption

Possible causes for a faulty ignition coil

  • Mechanical damages
  • Internal short-circuits
  • Contact faults
  • Faults in the voltage supply due to e.g. low battery

Continue driving with a faulty ignition coil?

  • Possible, but not recommended – especially due to consequential damages.
  • When no ignition at all: driving not possible.
