    Abstract: Various methods and systems are provided for indexing an injector map and subsequently controlling fuel injection to an engine.

    Abstract: A method of controlling the combustion of a spark-ignition engine having application to gasoline engines is disclosed. An engine control system controls actuators so that the values of physical parameters linked with the combustion of a mixture of gas and fuel in a combustion chamber are equal to their setpoint values, to optimize the combustion. A setpoint value is determined for an ignition crank angle of the fuel mixture which is then corrected before the physical parameters reach their setpoint values. A correction to be applied to this ignition angle setpoint value is calculated so that the crank angle CAy is equal to its setpoint value. Finally, the engine control system controls the ignition of the mixture in the combustion chamber when the crank angle is equal to the corrected setpoint value to optimize combustion.

    Abstract: An electronic engine control (EEC) module executes both open loop and closed loop neural network processes to control the air/fuel mixture ratio of a vehicle engine to hold the fuel mixture at stoichiometry. The open loop neural network provides transient air/fuel control to provide a base stoichiometric air/fuel mixture ratio signal in response to throttle position under current engine speed and load conditions. The base air/fuel mixture ratio signal from the open loop network is additively combined with a closed loop trimming signal which varies the air/fuel mixture ratio in response to variations in the sensed exhaust gas oxygen level. Each neural network function is defined by a unitary data structure which defines the network architecture, including the number of node layers, the number of nodes per layer, and the interconnections between nodes. In addition, the data structure holds weight values which determine the manner in which network signals are combined. The network definition data structures are created by a network training system which utilizes an external training processor which employs gradient methods to derive network weight values in accordance with a cost function which quantitatively defines system objectives and an identification network which is pretrained to provide gradient signals representative of the behavior of the physical plant. The training processor executes training cycles asynchronously with the operation of the EEC module in a representative test vehicle.

    Abstract: A heat generation rate waveform of an internal combustion engine. A period from spark generated by an ignition plug to ignition of an air-fuel mixture is defined as an ignition delay period τ that is one of characteristic values of the heat generation rate waveform. When the ignition time FA of the air-fuel mixture is on the advance side of a compression top dead center of a piston (BTDC), the ignition delay period τ is estimated based on an in-cylinder fuel density ρfuel@SA at the spark time SA, and when the ignition time FA of the air-fuel mixture is on the delay side of the compression top dead center of the piston (ATDC), the ignition delay period τ is estimated based on an in-cylinder fuel density ρfuel@FA at the ignition time FA. Thus, the heat generation rate waveform is produced using the estimated ignition delay period τ.
