The cylinder pressure data of each cylinder is taken as an analogue input signal from
the pressure transducer into the ECS. For more data, see Fig. 3.

The ECS control system filters the signals from the sensors and then transmits these
signals to a controller. The measured value is adjusted to the correct set-point value
and is related to the engine load. This real-time site correction and
comparison is done for each engine cycle (see Fig. 4).
