摘要： Fuel metering control system in an internal combustion engine utilizing adaptive control having an intake manifold wall's fuel adherence plant. In the system, an actual air/fuel ratio in the individual cylinders is accurately estimated using an exhaust manifold model with an observer. Also, an actual cylinder air flow is estimated using a fluid model. Based on them, a desired cylinder fuel flow is determined by dividing the actual cylinder air flow by a desired air/fuel ratio and an actual cylinder fuel flow is determined by dividing the actual cylinder air flow by the estimated actual air/fuel ratio. The adaptive controller operates such that the actual cylinder fuel flow constantly coincides with the desired cylinder fuel flow. In an embodiment, in order to respond the change in wall adherence parameters, a compensator is connected in series with the wall adherence plant, a virtual plant incorporating the compensator is postulated and when the transfer characteristics of the virtual plant is other than 1 or thereabout, the adaptive controller is operated to have a transfer characteristics inverse thereto. At the same time, a method for estimating cylinder air flow inducted in the engine using the aforesaid fluid model is explained.

摘要： The invention discloses a system for adjusting the richness of the air-fuel mixture injected into an engine. It is characterised in that the adjusting device is of the 'Smith predictor' type (30) that comprises at least one control loop (36, 38) which computes a first estimated correction value δ of the richness RISUIV which takes into account the delay introduced by the engine (10). The invention is useful for fuel injection internal combustion engines.

摘要： A method and system for adaptive transient fuel compensation in a cylinder of a multi-cylinder engine estimates fuel puddle dynamics for the cylinder by determining parameters of a wall-wetting model every engine cycle. Fuel delivery to the cylinder is adjusted dependent on the estimated fuel puddle dynamics. An adaptive controller (203) is characterized by three components, an adjustable compensator (207), a wall-wetting model (215), and a parameter adaptation algorithm (221). The adjustable compensator (207) receives estimates of a parameter C (223) and of a parameter bv (225) directly from the parameter adaptation algorithm (221), and adjusts fuel injected (213) dependent on the parameter estimates (223 and 225) and a desired fuel demand (205).

摘要： A fuel metering control system for an internal combustion engine including a feedback loop having an adaptive controller and an adaptation mechanism that estimates controller parameters θ̂. The adaptive controller calculates a feedback correction coefficient that corrects the quantity of fuel injection to bring a controlled variable obtained at least based on an output of an air/fuel ratio sensor, to a desired air/fuel ratio. The convergence speed of the controller parameters are determined by a gain matrix. The gain matrix is determined in response to at least one of the detected engine operating conditions.

The adaptive controller corrects the quantity of fuel injection to bring a controlled variable obtained at least based on an output of said air/fuel ratio sensor, to a desired value. Estimation error of the controller parameters are defined by an error signal e*. The system is configured such that the signal is compared with a limit value and is replaced to a predetermined value when the calculated estimation error signal exceeds the limit value.
