Adriadiesel d.d. is the successor of the former diesel engine factory Jugoturbina and continues the tradition of producing diesel engines, spare parts and other equipment. We offer machining services for parts made of alloy and steel materials - standard up to a weight of 25t, exceptionally up to max. 70t, the service of heat treatment of annealing positions of large dimensions can be carried out in our large annealing furnace (6.5 m length / 3.5 m width / 2.5 height), we can offer heat treatment services of positions: hardening, improvement, cementation, nitriding , annealing as well as welding services by MAG, MIG, TIG, REL procedures performed by certified welders.
Among other things, Adriadiesel also offers machining services for positions of larger dimensions, for example CNC Portal milling machine 66K 25 PM F4-06 is able to machine positions 2.5 meters high, 2.5 meters wide and even up to 6 meters long and weighing up to 70 tons.

Chilean iron ore miner Compania Minera del Pacífico (CMP) has signed an alliance with ENGIE Chile, which they believe represents an important step in decarbonizing the mining industry. The project plans to convert two trucks from diesel-burning systems to dual-fuel systems within six months. There is already international dual-fuel mining truck experience – mines in Mexico, Turkey, Russia, Australia, the US, Canada, etc. – showing the same results. Chilean authorities have approved a pilot project to convert Chile's entire fleet of CMP mining trucks to dual-fuel. The project is in the first phase of development and implementation and will take place at CMP's Los Colorados mine in the Atacama region. Chile and CMP aim to accelerate a carbon-neutral economy through proven technological solutions.
Research on diesel engines has become increasingly important as engine manufacturers seek to reduce carbon dioxide emissions. There are significant advantages to using a diesel piloted natural gas engine as a DF engine. Different combustion patterns exist due to changes in mixture formation. The delay in the timing of the second pilot injection increased THC emissions (maximum 4.27g/(kW h) at low and medium loads) and reduced NOx emissions (7.64g/km) but increased and then subsequently decreased thermal efficiency value.
This article describes the D242 diesel engine configuration with a modified design for gas-diesel operation using compressed natural gas. Practical studies allow the maximum valve opening angle on the intake stroke to be adjusted for various operating modes and to evaluate the efficiency of modifications to the diesel engine design. The proposed design modifications have been evaluated in terms of the environmental impact of using natural gas as an engine fuel for diesel engines.
The Sakigake tugboat, operated in Tokyo Bay by NYK group company Shin-Nippon Kaiyosha Corporation, is scheduled to complete its renovation in 2024. The project was adopted by Japan's New Energy and Industrial Technology Development Organization (NEDO) as part of the Green Innovation Fund program for the development of ships equipped with domestically produced ammonia-fueled engines.
