It All Starts Here…Industrial gas-fired engines are mechanical marvels that require robust ignition systems to breathelife into them and keep them firing at peak efficiency. Altronic manufactures a family of ignitionsystems designed to meet the requirements of virtually any engine. More of these systems are in thefield today than all other brands combined, a testament to their quality and reliability.Solid-state ignition systems operate via aself-contained alternator that charges anenergy storage capacitor. Magneticallytriggeredpick-up coils provide timingpulses that discharge the capacitor intimed sequence, routing low-tensiondischarges to the ignition coil. Electronicsare mounted on easy-to-replace plug-inmodules. Drive couplings are furnished insynthetic elastomer materials for low wearand long life.Disc-triggered digital ignition systemsemploy a cylinder position sensing design,typically using a single pickup and onetrigger event per cylinder, which may bederived from an Altronic timing disc orholes/protrusions in the engine flywheel orcamshaft gear. The pickup and timing discprovide accurate timing reference signalsto the ignition unit, which calculatesthe correct ignition timing point. Theseinnovative and reliable systems can beapplied to a variety of engines, includingheavy-duty vehicular applications aswell as engines incorporating lean-burntechnology.Crankshaft-referenced ignition systemsuse a continuous crankshaft-sensingdesign. A magnetic pickup inputs signalsfrom the engine ring-gear or holes drilledin the flywheel; a second pickup sensesa revolution/reset event giving preciseinformation on the location of the crankshaft.On 4-cycle engines, a referencesignal at engine camshaft speed is usedto determine the compression cycle. Areplaceable memory chip, programmedwith the engine’s application data, operateswith the CPU’s digital circuitry tooutput precise firing pulses to the ignitioncoils. Altronic CPU systems eliminate mechanicalwearing parts — gears, chains,couplings, etc.
