VERFAHREN UND VORRICHTUNGEN ZUR STEUERUNG DES KRAFTSTOFF-LUFT-VERHÄLTNISSES EINES VERBRENNUNGSMOTORS

摘要

Methods and devices for controlling the normalized air-fuel ratio of an internal combustion engine, otherwise known, in technical terms, as Lambda. The present invention is based on the use of the ionization current released by a device positioned on each cylinder of the engine. This ionization current is measured by a Control Unit equipped with a low-pass filter and electronic means which implement the invention.
