Product Overview: 

The IntelliSpark 32/16/8 series ignition systems are capacitive discharge, low-tension type designs. The system is capable of generating precise spark timing that improves fuel economy, load balance and ignition stability. The controller design incorporates a state-of-the-art 16-bit microcontroller. This technology provides users with a highly flexible solution to meet their ignition needs.

The user can choose from one of five methods of crankshaft sensing for a 4-stroke engine and two methods for a 2-stroke engine.

Murphy’s smart ignition coils used with this product incorporate a sense lead connection for real-time spark plug demand voltage measurements by the ignition controller. This allows the controller to:

  • Measure demand on each cylinder’s plug for diagnostic purposes;
  • Automatically control the energy delivered to the smart coils to optimize spark plug life;
  • Use the measured demand in the unique camless crank method to determine the compression stroke, eliminating the need for a camshaft sensor.

Several smart coil designs are available to accommodate specific ignition requirements including: remote mount coils and plug-mounted (integral) coils, non-hazardous or CSA Class I, Div. 2 rated versions.

This system also includes the Murphy PV-450 full-color screen display for control functions, monitoring, programming and diagnostic testing. The eight-button display includes comprehensive built-in help files and wiring information for the coil harness and a database of common engines for ease of configuration.
