AN EXPERIMENTAL INVESTIGATION OF AN ELECTRONIC CONTROL SYSTEM USING NEW CONTROL ALGORITHMS

An experimental study for a microcomputer engine control system has been undertaken to obtain higher driveability during transient conditions, and good fuel economy during light load conditions. New control algorithms based on learning and adaptive control methods were adopted. By adjusting the parameters for calculation of control outputs using a stoichiometric combustion sensor as a reference, the driveability and exhaust emissions in transient drive conditions were greatly improved by decreasing deviations and delays in the air-to-fuel ratio. Under the new algorithms, higher performance was obtained for long periods by reducing the total fuel consumption through use of leaner combustion control technology.
