Electrical interface assembly for reducing ohmic losses in an ignition system

Abstract

An electrical interface assembly is provided for an ignition system including at least one ignition coil per cylinder in a multi-cylinder engine. Each ignition coil includes a plurality of coil terminals for passing respective electrical signals. One of the electrical signals may be used for discharging a respective spark in a respective cylinder. The interface assembly comprises a respective miniaturized printed circuit board (PCB) on each ignition coil. Each miniaturized PCB is electrically coupled to the coil terminals therein. The interface assembly further comprises a separate electrically conductive structure for electrically interconnecting each miniaturized PCB. The electrically conductive structure may be configured to reduce ohmic losses due to inter-cylinder separation in the electrical signal used for discharging the respective spark.
