Standard Motor Products Europe (SMPE) has added a range of multicharge ignition coils to its product portfolio, with the component having been recently introduced to gasoline direct injection (GDI) engines.
Multicharge ignition coils are designed to fire multiple times per cycle. After the initial spark, the coil is sparked multiple times, which is possible due to the much shorter dwell time than standard ignition coils.
This allows for an extended spark duration that produces more spark energy, optimising combustion in GDI engines. More economical injection is also achieved thanks to higher efficiency in the combustion process, minimising soot and particulate emissions, and therefore boosting fuel economy.
