<p>A cylinder jacket (4) provided with a top plate (21) exhibiting a rectangular shape as viewed from the top, a bottom plate (22) exhibiting a rectangular shape as viewed from the bottom, a front plate exhibiting a rectangular shape as viewed from the front, a back plate exhibiting a rectangular shape as viewed from the back, exhaust-side side plates (23), each exhibiting a rectangular shape as viewed from the right side, fuel-pump-side side plates (24), each exhibiting a rectangular shape as viewed from the left side, and partitioning plates (25) that partition adjacent cylinders, wherein linking holes (37) that link adjacent spaces, formed in two adjacent partitioning plates (25), or the front plate and the partitioning plate (25) adjacent to the front plate, or the rear plate and the partitioning plate (25) adjacent to the back plate, and the exhaust-side side plates (23), and the fuel-pump-side side plates (24) are formed on the partitioning plates (25) at a position, shape as viewed from the front, and size, at which the difference between the amount that the exhaust-side side plates (23) stretch due to pressure inside the cylinder, and the amount that the fuel-pump-side side plates (24) stretch due to pressure inside the cylinders, is minimized.</p> |
