Embodiment Construction

[0057] Figure 1-11 The machining device according to the invention is shown in the form of a grinding or lapping device 10, which is connected to the upper open end 1A of a cylinder liner 1 in an internal combustion engine E for propelling a spaceship and / or in to generate heat and / or electricity in a spaceship, or to generate heat and / or electricity in a stationary power station. Preferably, the grinding device 10 is used in large two-stroke diesel engines with large piston diameters, but can also be used in small and medium-sized engines, as well as in four-stroke diesel engines and Otto engines.

[0058] exist figure 1 and 10 In , a grinding device 10 is shown with parts of the cylinder liner 1 removed for reasons of clarity. The grinding device 10 is arranged on the partially shown cylinder liner 1 by means of an axially symmetrical cylindrical clamp 20 whose lower end is connected to the mating guide surface 2 on the cylinder liner through a flat guide surface 21 and...

Abstract

A method for internally machining the inner surface of cylinder sleeve for IC engine is disclosed. Its apparatus is composed of a detachable grinding tool and a drive unit for driving said grinding tool.

Description

technical field [0001] The present invention relates to a method and apparatus for providing a corrugation pattern on the inner surface of a cylinder liner in an internal combustion engine. Background technique [0002] Internal combustion engines, in this case Otto engines and diesel engines, wear out in use due to wear between cylinder liners and piston / piston rings, especially both for propulsion of aircraft, especially dirigibles, and for use in these aircraft or A large engine that produces electricity and / or heat in a stationary power station. In some cases, most of the wear occurs during start-up and break-in of new and reconditioned engines. [0003] To reduce wear during start-up, break-in and operation, a wavy, sometimes helical pattern - also known as a corrugation pattern - is provided on the inner surface of the cylinder liner. This wavy pattern helps retain more lubricant on the inner face of the cylinder than the reticulated / crossed pattern produced during c...
