5 Operation
5.1 Runtimes at partial load
Gas engines are designed and optimized for continuous operation at 100 % load.
The following restrictions apply to ensure maximum operational availability of the engine plant and to reduce
maintenance to a minimum:
Mechanical cylinder output
Recommended maximum run-
time
at this load
Recommended minimum run-
time
in subsequent operation
at load > 50 kW
mech
/ cylinder
5 to 20 kW
mech
/ cylinder
30 minutes without interruption
max. 25 hours per year
120 minutes
20 to 50 kW
mech
/ cylinder
max. 5 hours without interruption
max. 25 hours per year
120 minutes
50 to 100 kW
mech
/ cylinder
No restriction
No restriction
Engine operation below a load of 5 kW
mech
/cylinder is to be reduced to a minimum (only for start-up and
shut-down operations).
A minimum operating time of 2 hours per start is recommended to counteract increased engine loading re-
sulting from temperature changes (cold start to engine operating temperature).
Important
The nitrogen oxide emissions specified in the technical data are only observed as of 50 kW
