||During research works concerning piston internal-combustion engines specifications of these objects are often needed. This data is usually dispersed and reaching to some is hampered or impossible. Therefore, an electronic database was drawn up about the most important ship producer’s piston internal-combustion engines for needs of exploitation investigations in the destination of gathering the necessary information. This paper presents a database of global marine diesel engines. For example, engines of the following companies were described: Akasaka Diesel, CAT, Cummins, Fiat, Hyundai, MTU, Niigata Power Systems, Pielstick, Scania, Volvo Penta etc.
Information was obtained from various sources, so as websites of producers, advertising catalogues, or books and magazines about subject matter associated with marine diesel engines. This information was collected and written with the help of the program Microsoft Office. Gathered data was divided in engines of the main drive and emergency, containing details about producers, types and parameters of 2-stroke engines and four-stroke. The base enables supplementing and the alteration of entered data. Produced engines are usually operated by several dozen years after producing on swimming objects. Produced internal combustion engines are usually operated by several dozen years after producing on floating objects, and producers are merging or are stopping existing.
