Ignition Control Systems

MPI Control Systems utilize the latest microprocessor based designs to provide improved programming and diagnostics for today's industrial gas engines. Operators of MPI controllers have more information to be used locally or remotely, giving them "full authority" to fine tune their operations for enhanced efficiency. Click here to learn more.

CD Ignition Systems

A self-powered capacitor discharge ignition system which can be installed on any large flywheel, spark-ignited engine. With electronics engine-mounted in close proximity to the flywheel, the unit is powered by magnetic charging circuitry. MPI offers this inexpensive, proven design with no moving parts to wear out.

Magneto Replacement Parts

An array of new and rebuilt Magneto Replacement Cores are available from MPI to provide powerful start-up assistance for a wide variety of engines and applications. Magneto 3 and 5 sizes are available for 6, 8, 12 and 16 cylinder engines. These economical, high quality magneto cores guarantee surefire starts. Click here to learn more.

Detonation Sensing Interface System

The MPI Detonation Sensing Interface System utilizes a pair of highly sensitive accelerometers to detect detonation. In the event of detonation the DSI signals the MPI Control System, via 4/20 ma control signal, which responds by immediately retarding the timing thus eliminating the potentially harmful effects of continuous detonation.
