<p>An ignition unit included in the ignition system of an internal combustion engine and including a plurality of finger-like connection pieces (2) extending from a common upper part (4) in the ignition unit and connectible to a corresponding number of spark plugs in the engine, said upper part including an electronic unit with components included in a high-tension block, each connection piece (2) including an ignition element (20) with an ignition coil for generating ignition voltage, as well as a connection device (22) for connecting and for transmitting high-tension current to the engine spark plugs. The invention has the task of enabling rational manufacturing and design of an ignition unit, which meets high demands for loss-free and reliable voltage transmission between parts included therein. To this end, the invention is distinguished substantially in that each ignition element in the ignition unit has cable-free electrical connection both to contact means (47) in the upper part (4) and to contact means (27) in its connection device (22). The implementation reduces risk of electrical faults, which may also be explained by each ignition element (20) being enclosed in a surrounding protective sleeve (18).</p> |
