Abstract (en)
[origin: EP0886055A1] The connector control process involves controlling injection using calculating electronics. The calculating electronics has three parameters which are applied respectively to controlling air, sparking and richness of a combustion mixture. Linear dynamics of the production of the connector is performed using a logarithmic function and its inverse during engine development. An optimal gain is also calculated during engine development. When the engine is running the calculating electronics determine state variables at each neutral point. A magnitude of a mass of air absorbed and a mass of air exiting a collector as well as mixture richness are calculated. Real and projected coupling values are determined. Control variables for a linear quadratic integral are calculated.
