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.

"The Edvard Kardelj factory from Karlovac produces seven-horsepower DMT diesel engines outside its production program. Agricultural and fishing cooperatives have a 40 percent discount on the sale price."

Jugoturbina worked to satisfy its employees not only through working conditions but also to improve the living standards of all its employees and other citizens of Karlovac. Thus, during the years of its business, Jugoturbina organized various excursions and gatherings (Dance on Plitvice), opened a workers 'resort in Punat on Krlo, built a children's playground on Švarča, and organized workers' sports games in Karlovac.

Legal regulations made it possible to reunite the financial function of the entire system by establishing internal banks in large systems, such as Jugoturbina in 1978, whereby internal banks were given the opportunity to perform some banking operations to a limited extent. Taking into account the rational spending of liquid assets in the entire system of Jugoturbina, the decision was made to establish the Internal Bank SOUR Jugoturbina.

"On May 1, our first steam turbine factory" Edvard Kardelj ", which was built in Karlovac, will start operating. The factory can also produce marine engines, and has 18,000 square meters of halls and a production plant."

"The transitional flag of the Central Committee of the Federation of Trade Unions of Yugoslavia was awarded to the factory "Edvard Kardelj" from Karlovac, because the workers mastered complicated production. In addition to that recognition, the best workers were awarded 70,000 dinars in cash. "

With the strengthening of the role of foreign trade and the sale of increasingly complex facilities in our country and in the world, there is a need to separate engineering from production to a specialized organization.

Also, marketing in that period begins its first steps, so in addition to the development of marketing in Jugoturbina, other foreign trade services are being developed that can monitor all types of the most complex foreign trade operations.

"I order that a steam turbine factory be built in Karlovac for the needs of the millitary and the merchant navy. It will be named after Edvard Kardelj." General Ivan Gosnjak
