Definitions
- the number 1 in FIG. 1 represents an internal combustion engine with four cylinders 2, 3, 4 and 5.
- the cylinders are supplied with air or a fuel / air mixture from an intake manifold 6.
- the amount of air drawn in by the cylinders is determined by a
- Air quantity actuator 7 for example a throttle valve, controlled.
- the amount of air flowing into the cylinders can also be controlled by a variable valve control.
- An air flow meter 8 measures the amount of Air sucked in by the internal combustion engine.
- the speed n of the internal combustion engine is detected by a speed sensor 9.
