The IntelliSpark® product line, formerly known as Murphy Power Ignition (MPI), maximizes the power of industrial spark-ignited natural gas-powered engines while providing a more cost-efficient, emission-controlled operation.

These advanced microprocessor-based ignition controllers, ignition coils, output harnesses, and brushless alternators give operators more information, control and authority over their engine and driver applications.


IntelliSpark® Ignition Controller System


The IntelliSpark® 32/16/8 Series Ignition Controller Systems are capacitive discharge, low-tension-type designs. The systems are capable of generating precise spark timing that improves fuel economy, load balance and ignition stability.

This system includes the Murphy PV-450 full-color screen, featuring a comprehensive eight-button display for control functions, monitoring, programming and diagnostic testing. There are five methods of crankshaft sensing for a 4-stroke engine and two methods for a 2-stroke engine.

•   Crankshaft-referenced 16-bit microprocessor based system
•   Patented Smart Coil™ technology
•   Automatic energy control
•   Two field-adjustable timing schedules
•   Optimized engine combustion and performance
•   True primary and secondary diagnostics

Ignition Coils


Murphy's Smart Coil™ instruments are patented, and are used with IntelliSpark® Control Technology to provide real time diagnostics and prognostics. The ignition coil is one of the most critical components of any ignition system. When properly matched to the ignition controller’s output, the ignition coil ensures optimum performance and reliability.

All Murphy coils are manufactured with durable, high quality construction, and many are direct replacements for Altronic coils.

•   Open Mount, Flange Mount, Integral Plug Mount and Remote Mount designs
•   Compatible with CD ignition systems for industrial engines
•   Multi-purpose designs to fit wide range of applications
•   Accurate monitoring of engine conditions
