Engine system for ships

Patent ·
OSTI ID:6734908

This patent describes an engine system for ships, comprising: an engine body including a main combustion engine for transmitting the power generated by explosion pressure to a pumping piston and a power transmission apparatus for transmitting to a power crank shaft the power that is increased by the ratio of the cross-sectional areas of a combustion chamber piston to a power piston, wherein the stroke distance of the combustion chamber piston is equal to that of the power piston; one or more swash plate-type stirling engines coupled to the exhaust gas outlet of the main combustion engine to be driven by the exhaust gas heat; a single-stage screw-type compressor coupled by the drive shaft to the swash plate-type stirling engine; thereby generating a great amount of compressed air; a compressed air source connected to the compressor for storing a great amount of compressed air from the compressor; a booster connected between the compressed air source and the power transmission apparatus to amplify the air pressure derived from the compressed air source and then to provide the amplified air pressure to the power transmission apparatus by operation of the cam in accordance with the rotation of a crank shaft; an accumulator in communication with the power transmission apparatus through a fluid oil pipe, thereby maintaining constant control of the oil pressure in the power transmission apparatus; and a compressed air control device for intake and exhaust of compressed air which is added and released to/from the pumping piston of the power transmission apparatus.
