Abstract: The present invention relates to a ship waste heat power generation system utilizing waste heat from ships. Specifically, the present invention relates to a ship waste heat power generation system utilizing waste heat from ships, wherein recovers exhaust gas waste heat and engine cooling water waste heat from ships using various fuels such as diesel, LNG, and dual-fuel. The recovered waste heat is used as a heat source, while seawater serves as the heat sink, generating electricity through the Organic Rankine Cycle (ORC). By combining exhaust gas waste heat and engine cooling water waste heat, which have different waste heat temperatures, in parallel or series to reduce the evaporation heat capacity, the ORC output is enhanced.

Abstract: Proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. More particularly, proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. The ship cogeneration system is configured to generate electric power by recovering waste heat generated from an LNG engine and providing high-temperature and high-pressure steam discharged from the economizer to an evaporator of an organic Rankine cycle. The ship cogeneration system is capable of removing soot generated on a contact surface between the exhaust gas of the LNG engine and the economizer by using some of the high-temperature and high-pressure steam.

Abstract: A cylinder block includes an extension portion that is shaped to extend toward the cylinder liner and is formed on an end portion of the cylinder block so as to form a surface contact with a head gasket. In particular, the cylinder liner includes an end portion forming an accommodation groove portion that is shaped to correspond to the extension portion, and a part of the end portion of the cylinder liner is supported on a circumferential surface of the extension portion and is linked to the accommodation groove portion. In addition, the part of the end portion of the cylinder liner forms a surface contact with the head gasket.

Abstract: When forming a three-dimensional object by laminating a plurality of cross-sectional layers, a 3D printer, a 3D printing method, and a 3D printer control program, according to one embodiment of the present invention, can improve the surface resolution of the three-dimensional object by dividing a cross-sectional layer into a plurality of cross-sectional images and using the same in order to form the cross-sectional layer.

Abstract: An engine oil supply system may include an oil pan connected with an oil pump at a first side and connected with an oil cooler at a second side, an oil passage through which oil pressurized by the oil pump flows, an oil filter disposed in the oil pan to filter impurities in the oil supplied from the oil pump, and a bypass valve disposed in the oil passage to selectively supply the oil in the oil passage to at least one of the oil cooler and the oil filter.
