Abstract (en)
[origin: US4508082A] An electronically controlled fuel metering system for an internal combustion engine is proposed which includes devices for damping engine jerking. The following signals are formed: ti (k) as the up-to-date load value; tiM as the up-to-date averaged load value; ti (k-1)+ DELTA ti/2 as a special load value for use in a transition into overrunning; and tiM+ DELTA tiM/2 for the purpose of successive approximation of the average value to up-to-date load values in the case of slow acceleration processes and flat courses of load reduction. A computer-controlled realization is possible for forming and selecting the individual values. A block circuit diagram is also provided for an electronically controlled fuel metering system made up of discrete modular elements.
