A classic feature of Sulzer Z-type engines SULZER ZA, SULZER ZAS, SULZER Z40, SULZER ZA40, SULZER ZA40S is the rotating piston. This Sulzer patented concept with cylinder bores from 90 mm to 420 mm for highly loaded trunk piston engines has the following benefits:
-Even temperature distribution around the piston crown
-Minimum piston skirt deformation
-Optimum sealing and working conditions for the piston rings
-Low and stable lubricating oil consumption thanks to the small piston running clearances
-Smallest risk of seizure between the piston and the cylinder liner
'When it comes to low routine maintenance schedule, MAN L28/32 offers a great advantage with 20,000 hours between overhauls when operated on HFO. A low level of deformation and a low level of mechanical stresses (i.e. low wear-rates) are achieved through its sturdy engine structure and amply dimensioned running gear.'
"Work on installation 3 generator sets Adria 40 in Rostov began in mid-August. On that occasion, during August and September, for supervision of two specialists from Adriadiesel and one from Končar GiM stayed in Rostov. Continuation of works on installation is expected in mid-November."

After the production of the first SULZER 12 ZV 40/48 engine in 1976, production started on an upward trajectory and by the end of 1977, two more SULZER auxiliary engines with the designation 12 ZV 40/48 were produced. Production under the SULZER license has continued for many years and Adriadiesel is still one of the leading suppliers of spare parts for engine repairs.
"An agreement was reached with the company ČKD PRAHA DIZ on a joint appearance in the Slovak Republic, in the nuclear power plant Mochovce, where we are about to contract the overhaul of six engines 6 ZL 40/48, and the start of work is expected during the first quarter of next year.
