Abstract (en)
[origin: EP0987422A1] A circuit (10) evaluates the mass (Meval) of the injected fuel and has inputs of values (n) for engine speed and (Da) for intake airflow. The same inputs are fed to a flow instability evaluation circuit (14). The flow instability evaluation circuit feeds signals to a regulator circuit (13) which also receives inputs from an instability calculation circuit (12) and the fuel mass flow circuit. The instability calculation circuit receives an input from an engine torque measurement circuit (11).
