7.6.2 Engine menu
The
Engine menu
is submitting detailed information about the actual and average fuel consumption per
consumer, total fuel consumption per engine, actual and average power per engine, total energy
consumed and engine efficiency.

Fuel consumption screen, one consumer

than one engine or consumer
When the PEM4 + SPU3 system is monitoring more than 1 engine or consumer, bar graphs representing
the fuel consumption per hour will be shown in bar graphs. These bar graphs are especially designed to
have immediate overview of the situation.
As a standard the PEM4 + SPU3 system monitors the fuel consumption per engine in
kg/hour. In case you prefer to read out all fuel consumption data in litres/hour you can
change the measurement unit in the
Settings menu
in the submenu Fuel type. Please be
aware that after switching from kg/hour to litres/hour and vice versa the value at the
accumulated fuel consumption counter is not correct.
The value at the Total Fuel consumption counter will be correct again after ticking the Reset
key.
In above fuel consumption screens the actual fuel type is shown per engine. The type of fuel can be set
per engine or consumer in the same Settings menu.
Average Fuel Consumption
submenu
Figure 23
–
Average Consumption screen
The four columns show the current fuel consumption and the averages over the last 1-4-24 hours. The
average fuel consumption over the last hours the vessel was sailing can easily be compared. Comparing
these values helps the crew to efficiently detect changes in fuel consumption per engine or consumer.
When the propeller shaft is rotating the PEM4 + SPU3 system is continuously recalculating the average
values.
In case the propeller shaft is not rotating the average values stay as they are. Average values will only
be displayed when the system gathered sufficient data to make a correct calculation.
