2.1 Pressure Transducers
The pressure transducer (1) (one for each cylinder) is installed on the cylinder cover
(see Fig. 1).
The technology (Pressductor
®
) of the pressure transducers (1) uses a
magneto-elastic measuring principle to measure the in-cylinder pressure. The
permanently measured in-cylinder pressure of all cylinders gives the necessary data
for the ICC system.
The pressure transducers (1) have a unique blow-through design. Usually, before the
engine starts, the indicator valves (2) are open and the engine is in slow turning
operation. Thus, possible combustion particles that remain (specially from HFO
operation) are blown out of the pressure transducers (1). This function makes sure
that the data is measured correctly and maintenance is decreased.
Note: For more data about slow turning, see 0220-1 Slow Turning.
