Popis: | In developing the turbocharged engine for the Audi Quattro, it became apparent at an early stage that this type of engine cannot be set up for maximum efficiency with conventional ignition systems. This is a result of the inflexibility of the mechanical spark control devices: the parameters that can be registered to control ignition timing are rpm and load condition (manifold pressure) only. By employing a microprocessor-controlled ignition system, it is possible to feed the engine with an optimum ignition timing signal for all load conditions. |
