The Best Quality and Technology, Being with Customer’s Satisfaction

Elite Manufacturing and Testing

 

    

MITSUBASHI engineers and manufactures high-quality ignition components at SMP’s 60,000 sq. ft. facility in Bialystok, Poland.

Highlights of the TS16949-certified facility include lean manufacturing methods and vertically integrated manufacturing processes that include multi-spindle winding, injection molding, potting, curing, and welding.

To ensure quality, all products manufactured at the facility undergo a full spectrum of measurement and life testing in addition to a full range of environmental analysis that includes thermal shock, thermal cycling, salt spray, vibration, and storage tests.

A coil-on-plug is designed to perform the functions of the ignition coil (creating the spark energy) and the spark plug wire set (containing and delivering the high voltage energy to the spark plug). To ensure proper function, MIS^® Coil-on-Plug Assemblies feature premium-quality components.

Ignition Coil Testing

We performed an extensive engineering analysis of OE DG500 and DG508 to MIS^®. The engineers measured winding resistance, inductance and output voltage, spark, energy, waveform peak voltage and ringing, as well as a complete physical and sectioned comparison to OE.

The Findings

MIS_^® Ignition Coils look, fit and perform like the original they relace with 100% end of the line production testing. The MIS^® coils also provide an improved secondary winding design (additional winding bays) that helps prevent internal arcing and high-voltage breakdown.

• The MIS^® coils tested 3.7% higher than OE in output voltage.
• The MIS^® coils were equal to OE in spark energy.
• In waveform testing, MIS^® coils’ peak output voltage was about 1000 volts higher than OE.
• The MIS^® coils had a longer spark duration than the OE, resulting in more energy supplied to the spark plugs.

The MIS^® coils match or exceed the OE coils in all categories and are an excellent replacement exceeding the OE performance.
