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.

Back in 1976, the first auxiliary engine under the SULZER license with the designation 12 ZV 40/48 was produced in Croatia, more precisely in the city on four rivers Karlovac, and in Karlovac there is still a company named Adriadiesel which is in charge of maintenance and supply of spare parts of that engine as well as all manufactured after it.
