Delphi Ignition Coils for Small Engines

Delphi Ignition Coils for Small Engines supply the required electrical energy needed to ignite air-fuel mixtures 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

Improved dwell accuracy decreases module and coil temperature for greater reliability
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

Typical Applications

Delphi Ignition Coils for Small Engines are designed for one- and two-cylinder gasoline 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 any customer package requirement, including: stand alone coil or coil and igniter package, coil with 2-pin or 3-pin connector, and coil shipped with or without screwed-in plug wire.
