LARGE TURBOCHARGED TWO-STROKE INTERNAL COMBUSTION ENGINE

Japanese Patent JP2017078419

A

PROBLEM TO BE SOLVED: To provide a large turbocharged two-stroke internal combustion engine of a crosshead type of which the weight and the cubic volume are minimized without large stress or vibration.SOLUTION: The present invention relates to a large turbocharged two-stroke internal combustion engine of a crosshead type comprising a lubrication fluid supply part, and at least one connecting rod having a first hole configured to be connected to a crosshead, a second hole configured to be connected to a crankpin and a rod part between the first hole and the second hole. The connecting rod has an axial extension and further comprises a fluid channel configured to supply the lubrication fluid to at least one of the first hole and the second hole. The connecting rod comprises a center part and a third hole. The third hole is arranged in the rod part closer to one of a first bearing and a second bearing than the center part, and the third hole is configured to modify a stiffness of the connecting rod at least in the axial extension.SELECTED DRAWING: Figure 1
