摘要： In an oil pressure generating device (200) of a crosshead engine, the plunger tail is located on the outer part of the main member, and the plunger head faces a pressure-boost chamber (216) inside the main member (202). The oil pressure generating device (200) has: plungers (210a, 210b) that slide in a direction intersecting the stroke direction of a piston; first pressing parts (236, 240) that are disposed apart from the main member in the sliding direction of the plungers, wherein the distance of separation from the main member is a first distance (La), and the pushing amount of the plungers into the pressure-boost chamber side is a first pushing amount; and second pressing parts (238), wherein the distance of separation from the main member is a second distance (Lb), and the pushing amount of the plungers into the pressure-boost chamber side is a second pushing amount that is greater than the first pushing amount. The oil pressure generating device (200) is provided with plunger pressing members (204a, 204b) that push the plungers to the pressure-boost chamber side while the plungers move from the first pressing parts to the second pressing parts.

摘要： Provided is a marine engine (100), including: a piston; and a compression ratio controller (182) configured to execute lowering processing of moving a top dead center position of the piston toward a bottom dead center side when an engine rotation speed falls within a resonance occurrence range set in advance. A geometrical compression ratio is reduced, and a resonance stress caused by a torsional vibration in a rotary system can thus be suppressed while suppressing a decrease in thermal efficiency compared with a case in which retarding control is applied to a fuel injection timing or a closing timing of an exhaust valve.
