Abstract

A cylinder jacket and a crosshead-type internal combustion engine provided with: a top plate (51) in which first through-holes (55) penetrating in the plate thickness direction are formed; a bottom plate (52) in which second through-holes (56) penetrating in the plate thickness direction and opposing the first through-holes (55) are formed; side plates (53) connecting the top plate (51) and the bottom plate (52); and attachment holes (59) which penetrate along the direction of penetration of the first through-holes (55) and the second through-holes (56), and through which a plurality of tie bolts (14) are inserted.

Description

technical field [0001] The present invention relates to a cylinder cover constituting an internal combustion engine such as a diesel engine or a gas engine, and a crosshead internal combustion engine provided with the cylinder cover. Background technique [0002] In general, internal combustion engines such as gas engines and gasoline engines that generate power by combusting fuel in cylinders have a crankshaft arranged below a plurality of cylinders along the direction in which the cylinders are arranged. The crankshaft is connected to the piston, and is rotatably supported by the crankcase via bearings. On the other hand, in an internal combustion engine with a large bore-to-stroke ratio mounted on a large ship, a crosshead is provided between the piston and the crankshaft. In the crosshead type internal combustion mechanism, a frame is arranged on the upper part of the base plate that accommodates the crankshaft, and a cylinder cover is arranged on the upper part of the ...
