When the main engine is driving a propeller shaft line equipped with a T-Sense
®
sensor the SFOC rate
will inform you about the Specific Fuel Oil Consumption in g/kWh of this engine. The Engine Efficiency
submenu will give you an overview of the amount of fuel consumed per engine and the power delivered
at the shaft per engine. The SFOC rate is a key performance indicator for engine efficiency.
As an option the efficiency of the Auxiliary engines in combination with the generators can be monitored.
In case lubrication oil consumption is measured the PEM4 + SPU3 system is able to calculate the SCOC
value representing the Specific Cylinder Oil Consumption in g/kWh.

Engine Efficiency Corrected screen single screw
When the main engine is driving a propeller shaft line equipped with a T-Sense
®
sensor the SFOC rate
will inform you about the Specific Fuel Oil Consumption in g/kWh of the engine. The Engine Efficiency
Corrected submenu will give you an overview of the amount of fuel consumed using the user determined
calorific value of the fuel. The SFOC rate is a key performance indicator for engine efficiency. The calorific
value of the fuel can be set using the Fuel menu (
Settings
tab). The calorific value of the shop can be set
using the System menu (
Settings
tab, Advanced user only).
