ABSTRACT:
A cartridge unit included in an ignition system of an internal combustion engine includes an upper metal part which is securable to an adjacent part of the engine and a plurality of finger-like connection casings, one for each spark plug, detachably mounted to and extending from the upper part. The connection casings and the upper part, when attached to each other, form an essentially closed inner space encapsulating a high tension block which includes a plurality of ignition coils for generating ignition voltage. Each ignition coil has a cable-free detachable electrical connection with adjacent parts of the high tension block, a plurality of contacts, one in each connection casing for cable-free transmission of high tension current from the ignition coils to the spark plugs, and a plurality of sealing elements, one for each connection casing, each sealingly surrounding a spark plug when the cartridge unit is connected to the spark plugs, a plurality of the finger-like connection casings being formed in one piece attachable to the upper part of the cartridge unit.
