Ignition Coil C90i-WG

This single fire coil was developed for the use e.g. in GDI (turbocharged) high performance engines. It is designed to connect a high voltage wire on the coil.

The main benefit of this high performance coil is its high energy capability.

Features

  • Max. 35 kV
  • Max. 90 mJ
  • Connection for high voltage wire
  • Max. 15,000 1/min
  • Developed for Turbo-GDI engines

Installation Notes

During mounting of the spark plug please pay attention that full clamping and proper contacts are made to ensure safe connection between coil and spark plug (high voltage wire).

This coil is only for use with engine control units having an integrated ignition power stage, e.g. IGBT IRG4BC40S or BIP.

For technical reasons the values of the coils may vary.

Please regard the specified limit values (see “Electrical Data”).

Usage above Iprim = 16 A or 35 kV may reduce the lifetime.

Please find further application hints in the offer drawing at our homepage.

 

Design Note

We strongly recommend the design of the spark plug shaft has to ensure that there are no sharp edges in the shaft geometry due to design or machining. Only in compliance with this recommendation, a proper function can be ensured.
