Delphi Compact Modular Ignition Coils
Delphi Compact Modular Ignition Coils is an all-new family of innovative
ignition technology developed for modern engines. The coils do not require
rare earth magnets, thus enhancing application flexibility and mitigating the
potential for costly material price fluctuations. They offer manufacturers
wide design flexibility, compact size to help overcome packaging
constraints, lower cost versus conventional ignition coils, and impressive
performance and durability to meet the most stringent program
requirements.
Delphi’s Compact Modular Ignition Coils include plug top ignition coil,
waste spark coil pack and coil near plug designs. The family also includes
a high energy density coil for high-end, space limited applications, and
which is available with or without rare earth magnets. It is a very compact,
premium coil, the smallest in the industry.
Delphi’s Compact Modular Ignition Coils are designed to operate
dependably and reliably under all operating conditions and throughout the
entire engine speed range. They are able to supply the required electrical
energy needed to properly ignite the air-fuel mixture in an engine’s
combustion chamber so engine performance, exhaust emissions and fuel
economy objectives can be achieved. They are also designed to meet a
wide variety of continually evolving requirements for combustion
calibrations.
