Abstract

In addition to knowing the various types of machining components that exist, operators are required to know the maintenance and be able to measure each component so that the diesel engine's performance does not experience problems that result in decreased engine performance. Meanwhile, the supporting components of the diesel engine are like cylinder liners, because the cylinder liner components determine the volume of the cylinder and the performance of the diesel engine. The shape of the cylinder liner is like a tube where the manufacturing process uses a horizontal centrifugal casting process. Horizontal Centrifugal casting process is a casting process for making cylinder liners by pouring molten metal into a rotating mold. Implementation of Top Overhaul on diesel engines is carried out by opening the cylinder head or the top of the engine. The parts examined include the rocker arm, inlet and exhaust valves, injectors, air starting valves and push rods. Top Overhaul is carried out when the working hours of the diesel engine have worked with around 6,000 hours of work. Major Overhaul maintenance, which includes inspection, maintenance and inspection carried out on all Top Overhaul works and on the piston, connecting rod, piston ring, seated metal and road metal. Major Overhaul maintenance is carried out when the diesel engine has 12,000 working hours according to the Diesel Engine Intruction Book. In the cylinder liner often occurs damage or looseness which is commonly referred to as abrasion, erosion and corrosion. Because of that the cylinder liner requires maintenance and measurement using an inside micrometer tool. From the results of the measurements and maintenance on the cylinder liner, the calculation of the consistency, taper and wear was obtained, to find out the specifications or exceed the limits specified in the Main Engine Intruction Book on the ship.

Abstract

The research conducted is an analysis of the effect of the main engine rotation (main engine) which tends to change during operation on the exhaust temperature of the main engine on a container ship with a weight of 35981GT. We conducted this research on a container ship KM SPIL Citra PT Salam Pacific Indonesia route during a cruise from Balik Papan Port, East Kalimantan to Bitung Port, North Sulawesi. The purpose of this research is to understand and find out how the main engine speed is determined accordingly so that the main engine exhaust gas is stable and not too high which causes the main engine performance decrease. The test is carried out when the ship is sailing in the middle of the sea in full away condition, the main propulsion engine (main engine) operates at 0.52 Rpm to 57 Rpm with an average running hour for each round of 4 hours. The maximum exhaust gas temperature obtained is 260 C. and the minimum temperature obtained is 230 C with an average temperature of cooling seawater and constant engine room temperature. The conclusion is known that the higher the main engine rotation, the higher the exhaust gas temperature of the main engine so that it is necessary to pay attention to the maximum Rpm limit of the engine so that high temperatures do not occur.

Abstract

Aluminum is an excellent material for making composites because it is lightweight, ductile, does not corrode easily and is easier to shape and fabricate. Various properties of existing aluminum, aluminum has mechanical properties that are not good, namely very low hardness. In a good method for processing aluminum, namely stir casting, why is this method used because it is quite cheap and easy to process by means of an alloy that is heated with an adjusted heat and stirred to mix all the existing composite materials and given reinforcement or grain refiner to obtain a good and evenly distributed composite metric without reducing the function of the existing composite. The method used in this study serves to improve the mechanical properties of a metal and SiC is used as a reinforcement and TiB is used as a grain refiner. SiC has advantages over other ceramic materials, namely it bonds easily with aluminum and does not cause oxidation of aluminum metal. Increasing the wetability of metal alloys with reinforcement, the technique used is by stirring when the liquid metal is in a semisolid phase. This research focused on variations in weight percent SiC powder 0%, 5%, 7.5%, and 10% and the addition of 5% Tib. To determine the physical and mechanical properties of the Al-SiC-TiB composite, several tests were carried out, namely density, porosity, hardness, bending and microstructure tests. The results of the tests showed that the highest density value was found at 0% SiC by weight at 2.70 gr/cm3, the lowest at 10% SiC at 2.65 gr/cm3. Porosity calculations show that the highest porosity value is found in 10% SiC by weight of 3.16%. The highest hardness test result was 10% SiC by weight at 72.6 HRB and the bending test result with the highest hardness value at 10% SiC by weight was 371.5 MPa. The test results show that the mechanical properties increase with the increase in the percentage of SiC powder up to 10% and with the addition of TiB the finer grains are produced so that the porosity decreases.
