Delphi Ignition Coils for Small Engines

Delphi Ignition Coils for Small Engines supply the required electrical energy needed to ignite the air-fuel mixture in an engine's combustion chamber. They are designed to meet a wide variety of continually evolving requirements for combustion calibrations.

Delphi Ignition Coils range from small inductive ignition coils to stand-alone smart ignition modules that can adjust spark timing to help provide economical fuel consumption and deliver optimal performance. They offer fully encapsulated coil, or coil and igniter circuits that provide reliable, robust performance under harsh off-road conditions.

Delphi Ignition Coils are designed to operate dependably and reliably under all operating conditions and throughout the entire engine speed range to help non-automotive engine manufacturers meet the highest engine performance, exhaust emissions and fuel economy objectives.

Benefits

  • Small packaging allows flexible engine layout
  • Higher voltage outputs compatible with alternative fuel requirements
  • Lower primary inductance provides high-speed performance
  • Early and precise electronic spark timing helps improve fuel economy and provides faster crank-to-run
  • Higher energy delivered to combustible mixture provides cleaner combustion
  • Improved dwell accuracy decreases module and coil temperature for greater reliability
  • RFI (radio frequency interference) and EMC (electromagnetic compatibility) compliant versions are also available

Typical Applications

Delphi Ignition Coils for Small Engines are designed for one- and two-cylinder gasoline and ethanol-blended fuel engines. They can be used for motorcycles, motor scooters, commercial products such as lawn mowers and stationary power generators, power sports products such as personal all-terrain vehicles, and marine engines. The coils are designed to meet virtually any customer package requirement, including:

  • Stand alone coil or coil and igniter package
  • Coil with 2-pin or 3-pin connector
  • Coil assembly with or without high voltage leads
