Opis:
The article refers to the common task of lubrication system. The fast development of the world's maritime sector, makes competition among countries increasing. Because of the deterioration of the global economy, the shipping companies, ship-owners want to reduce freight rates, to meet safety requirements, as well as improving conditions of exploitation and operating the machines to prevent the pollution of the marine environment. While exploiting the diesel engine in general and Sulzer diesel engines in particular, ship owners are always eager to reduce the operating cost and still ensure the engine running are safe and reliable. Provide an example of how to calculate the amount of cylinder lubricating oil according to the theory of slow-speed marine engines. The article refers to the costs of the operation and exploitation of ship, offer solution to reduce extraction costs by optimizing the amount of lubricating oil for the cylinders. The analyses in the article are based on Sulzer RTA engines. The article also refers to the level of actual lubrication oil for the cylinders of slow-speed marine engines during operation and exploitation based on the practical experience of the chief engineers, who had ever worked with these engines. The optimal adjustment of cylinder lubricating oil of Sulzer RTA diesel engines to reduce the operating cost but still ensure the engine running are safe and reliable and the problems need to be noted in the process of adjustment.

Opis:
Continuous monitoring of diesel engine performance under its operating is critical for prediction of malfunction development and subsequently functional failure detection. Analysis of Instantaneous Angular Speed (IAS) of the crankshaft is considered as one of non-intrusive and effective method of detection of combustion quality deterioration. The article contains presentation of attempt of monitoring of piston engine’s crankshaft torsional vibrations by measurement of Instantaneous Angular Speed at free, and power output ends of the engine’s crankshaft. The angular speed measurements was done using two optical sensors for reading the IAS, mounted at shaft line’s opposite ends, one at free end of the crankshaft and second at end of generator’s shaft. In the article is presented description of the measurement system and explanation of its mode of work. Experiments were based at two kinds of malfunction possible to be simulated at test bed. First one was simulation of a leak of fuel injection pump, the second one relayed on mounting of sets of injection valves with different nozzles characteristics (spraying nozzle angle), giving different parameters of fuel injection. Presented results of experiment derives from test cycle carried out using laboratory stand of Gdynia Maritime University equipped with 3- cylinder self − ignition engine, powering electric generator.
