Grinding System

An engine for marine propulsion and power generation consists of several cylinder liner-piston sets. And the oil groove is on the cylinder liner inside wall for the lubrication between piston and cylinder. The grinding processes of oil groove have been carried by manual work so far, because of the diversity of the shape. Recently, we developed an automatic grinding robot system for oil groove grinding of engine cylinder liners. It can cover various types of oil grooves and adjust its position by itself. The grinding robot system consists of a robot, a grinding tool head, sensors, a control system and setting equipment. The robot automatically recognizes the cylinder liner’s inside configuration by using a laser distance sensor and a vision sensor after the cylinder liner is placed on setting equipment. And grinding programs are generated on the basis of measured data. The grinding system of oil groove incorporating an industrial robot was successfully developed and can cover various cylinder types efficiently in this field. The developed system helps to increase productivity of cylinder liner and remove difficult works.

Overlay Welding

Inside of the cylinder cover for a large size engine, several specific areas are required to have endurable property for high temperature, high pressure and corrosion attack. For this purpose, the surface should be machined to the shape of a pocket and covered with inconel overlay welding. This paper represents the machining process using an industrial robot system, which can replace an expensive NC machine for the surface machining process. It also describes that how the robot generates its path from the CAD data and compensates its position with a laser distance sensor. The pocket machining system incorporating an industrial robot was successfully developed and can cover various engine types efficiently in this field.

Purpose This paper aims to investigate the wear behaviour of different materials for cylinder liners and piston rings in a linear reciprocating tribometer with special focus on the wear of the cylinder liner in the boundary lubrication regime. Design/methodology/approach Conventional nitrided steel, as well as diamond-like carbon and chromium nitride-coated piston rings, were tested against cast iron, AlSi and Fe-coated AlSi cylinder liners. The experiments were carried out with samples produced from original engine parts to have the original surface topography available. Radioactive tracer isotopes were used to measure cylinder liner wear continuously, enabling separation of running-in and steady-state wear. Findings A ranking of the material pairings with respect to wear behaviour of the cylinder liner was found. Post-test inspection of the cylinder samples by scanning electron microscopy (SEM) revealed differences in the wear mechanisms for the different material combinations. The results show that the running-in and steady-state wear of the liners can be reduced by choosing the appropriate material for the piston ring. Originality/value The use of original engine parts in a closely controlled tribometer environment under realistic loading conditions, in conjunction with continuous and highly sensitive wear measurement methods and a detailed SEM analysis of the wear mechanisms, forms an intermediate step between engine testing and laboratory environment testing.
