Abstract
Disclosed is an electronic system for computing control magnitudes for a control system of an internal combustion engine. The control magnitudes are derived by computation from measured auxiliary parameters. The control magnitude such as suction pipe pressure is computed from its relationship with the flow rate of air mass, or throttle valve position and rotary speed. Atmospheric pressure is computed from the air mass flow, rotary speed and throttle valve position or from the cross-section of the channel by-passing the throttle valve and from the supplied air mass. The computation arrangement can be either analog or digital.
