Technical optimisation for maximum performance<\/strong><\/p>\n

HG Motorsport high-performance ignition coils<\/strong><\/p>\n

Maximum ignition energy and thermal stability for modern high-performance engines.<\/p>\n

In modern vehicles, particularly those with tuned engines, original ignition coils quickly reach their limits. Misfires, uneven combustion and thermal overload are often the result. HG Motorsport high-performance ignition coils have been specifically developed to overcome these challenges. They provide increased ignition energy, improved thermal stability and consistently reliable performance, even under the most demanding conditions.<\/p>\n

Technical features of the HG Motorsport ignition coils<\/h3>\n
    \n
  • Optimised primary and secondary windings:<\/strong> more windings and high-quality copper wire provide improved energy transfer and consistently high ignition voltage.<\/li>\n
  • Increased ignition energy (+10% compared with OE):<\/strong> perfect spark-plug supply throughout the entire dwell period, ideal for high-performance engines.<\/li>\n
  • Consistent energy output under high load:<\/strong> particularly suitable for turbocharged and supercharged engines requiring stable ignition voltage over longer periods.<\/li>\n
  • Extended service life:<\/strong> high-quality insulation materials and optimised windings minimise thermal loads and protect against internal short circuits.<\/li>\n
  • Thermal resistance:<\/strong> continuous operation at up to 120\u00b0C and stable operation up to 140\u00b0C without loss of performance.<\/li>\n
  • Optimised spark formation:<\/strong> stable ignition even at high boost pressures and with richer mixtures, significantly improving combustion efficiency.<\/li>\n<\/ul>\n

    Ignition energy comparison<\/h3>\n

    The diagram shows the superior ignition energy of the HG Motorsport ignition coils compared with standard components:<\/p>\n

      \n
    • Up to 1.5 ms:<\/strong> both coil types deliver comparable energy.<\/li>\n
    • From 2.0 ms:<\/strong> the energy of standard ignition coils drops significantly, while the HG Motorsport ignition coils continue to deliver consistently high values.<\/li>\n
    • At 3.0 ms:<\/strong> the HG Motorsport ignition coils deliver almost 25% more energy, which is crucial at high engine speeds and in tuned engines.<\/li>\n<\/ul>\n

      Even at a temperature of 140\u00b0C, the ignition energy of the HG Motorsport ignition coils remains stable at 70 mJ, while OE coils have already failed or reached critical values.<\/p>\n

      Ideal for the following applications<\/h3>\n
        \n
      • High-performance engines:<\/strong> optimum ignition even under extreme loads.<\/li>\n
      • Motorsport and track days:<\/strong> stability and consistent energy during continuous operation.<\/li>\n
      • Daily drivers with increased power:<\/strong> improved efficiency and ignition stability in everyday use.<\/li>\n
      • Replacement for OEM ignition coils:<\/strong> greater reliability and longer service life.<\/li>\n<\/ul>\n

        Winding structure and operation<\/h3>\n

        The ignition coils use an optimised primary and secondary winding structure. The primary winding generates a strong magnetic field which, as it collapses, induces a high voltage in the secondary winding. The increased number of windings and improved insulation ensure consistent ignition energy, even at high engine speeds and peak loads.<\/p>\n

        Thermal testing and long-term results<\/h3>\n
          \n
        1. Continuous thermal load<\/strong>
          Test setup:<\/strong> continuous operation at 120\u00b0C with simulated load changes over 100 hours.
          Result:<\/strong> no reduction in performance or thermal degradation of the HG Motorsport ignition coils.
          Comparison:<\/strong> OE ignition coils lost approximately 25% of their energy after 50 hours, followed by initial material changes.<\/li>\n
        2. Additional test at 140\u00b0C<\/strong>
          HG Motorsport:<\/strong> stable operation for 8 hours without failures.
          OE ignition coils:<\/strong> performance drop of up to 40% after 4 hours, followed by thermal failures.<\/li>\n<\/ol>\n

          Summary of laboratory data<\/h3>\n
            \n
          • Maximum ignition energy:<\/strong> HG Motorsport 120 mJ, OE ignition coil 90 mJ.<\/li>\n
          • Continuous load at 120\u00b0C:<\/strong> HG Motorsport > 100 hours, OE ignition coil 50 hours.<\/li>\n
          • Functionality at 140\u00b0C:<\/strong> HG Motorsport stable for up to 8 hours, OE ignition coil performance drop after 4 hours.<\/li>\n
          • Insulation resistance (500 V):<\/strong> HG Motorsport > 20 M\u03a9, OE ignition coil approximately 10 M\u03a9.<\/li>\n<\/ul>\n
