Optronic Ignition Kit Standard Lumenition optronic ignition – standard utilising lumenitions revolutionary infra-red beam & rotating chopper trigger the optronic system is quite simply the best electronic ignition there is. immune to dirt cam wear & dust there are no parts to wear out & no maintenance is required. how it works: an optical switch is fitted to the same plate from where the points were removed & a plastic segmented chopper is slipped over the distributor cam. as the cam turns the chopper blade (one for each cylinder) interrupts the infra-red beam from being detected by the silicon phototransistor in the optical switch. these trigger pulses are sent on to the power module that charges the coil for a dead accurate and powerful spark. instant benefits include: – easier starting. – faster smoother acceleration. – reduced exhaust emissions. – better fuel economy.
