作動シリンダーとの間にアライメント誤差が生じる。(Prior Art and Problems) Conventionally, cylinder jackets for individual cylinders or for blocks consisting of a large number of cylinders for two-stroke internal combustion engines, especially low-speed marine diesel engines, have been It forms part of the system for cooling the liner and cylinder jacket, through which relatively hot water of 70°C to 80°C flows, and also a so-called "hot water" cooling section. In the case of , high temperature water of 100 degrees C or 6120 degrees C flows. However, the temperature of the scavenging air collected at the bottom of the cylinder jacket is between 40 degrees C and 50 degrees C. This temperature difference is due to the deformation of the cylinder jacket. This results in misalignment between the casing of the engine and the or each working cylinder.

ンジンの負荷が低い時にのみ作動可能である。In contrast to conventional constructions, the scavenging air chamber 13 expands in a tower upwards, so that the scavenging air within the jacket 4 flows around the area of the liner 6 above the scavenging air holes 16. The flow cools the jacket 4 and liner 6. A check valve 17 is provided in the air passage between the receiver 15 and the chamber 13 and is operated in a known manner to increase the scavenging air pressure by means of an auxiliary blower. The blower also delivers scavenging air from the receiver 15 to the chamber 13 parallel to the check valve 17, and it is also useful for the engine if the exhaust gas turbocharger is producing an inadequate scavenging pressure. It can only operate when the load is low.
