* Standard piston dismantling height, can be reduced with tilted piston withdrawal.
13- and 14-cylinder engines are only available in RT-fl ex versions, and not RTA versions.
All the above data apply to both RTA96C and RT-fl ex96C versions. However, there may be differences in weights
for the RT-fl ex96C.
Wärtsilä RT-fl ex engines are also available with part-load optimisation for lower fuel consumptions.
For defi nitions see page 39.
