This paper mainly studies the tribological performance of friction pairs and poor lubrication during piston movement. Based on the average Reynolds equation and comprehensively considering the variable viscosity and variable density characteristics of lubricating oil, a transient hydrodynamic lubrication model of the piston ring-cylinder liner fric...

Applying texture to a surface in a tribological interface will influence frictional performance, which has been investigated in several previous studies. However, since varying operating conditions heavily affect the frictional performance and optimum texture dimensions, more work in this field is required. There are few experimental studies concer...

Considering the surface roughness of piston ring and cylinder liner and deformation of cylinder liner, the friction dynamics calculation model of cylinder liner-piston ring friction pair was established. The effects of top ring, other piston rings and cylinder liner surface roughness on friction performance were analyzed by grouping comparison and ...

The main operating characteristics of cylinder liner include the liner deformation and coolant flow. The insufficient coolant flow can lead to greater deformation of cylinder liner and hence worse engine performance and emissions performance. However, previous works have been done focusing on the characteristics of liner bore deformation and compre...

The wear of the piston ring-cylinder system is inevitable in the operation of the internal combustion engines (ICEs). If wear exceeds the maximum, the piston ring-cylinder system will be failure. A novel wear assessment model is proposed based on the support vector regression, and the fuzzy uncertainty is modeled to describe the random behavior und...

The influence of errors in the processes of detection and then reduction of surface topography measurement noise is of great importance; many research papers are concerned with the definition of this type of measurement error. This paper presents the influence of high-frequency measurement noise, defined for various types of surface textures, e.g.,...

AbstractThe changes in the inside diameter of liners during honing without active control means and with their use are studied. The inner surface of the liner is shown to wear out to a greater extent in its upper part. The causes of wear are indicated. The most common method for restoring a liner is mechanical treatment of the inner surface to an i...

Advances in heavy-duty diesel engine designs place higher demands on the friction and wear performance of the piston ring and cylinder liner (PRCL) interface. The potential of using micro-textures machined on the whole stroke of a cast-iron cylinder liner was investigated in this work. A set of running-in and starved lubrication experiments was per...

Cylinder liners in heavy-duty truck engines are subjected to intense vibrations and may sustain damage from the cavitation of bubbles in the coolant liquid, with some risks of leakage and engine breakdown. An ultrasonic oscillating probe was used to simulate the pitting rates and behavior of samples extracted from cylinder liners, which are made of...

In Verbrennungsmotoren ist der Tribokontakt Topring gegen Zylinderlaufbahn einer der am höchsten beanspruchten Kontakte. Die Anforderungen an Reibungsoptimierung und geringen Verschleiß bei gleichzeitig hoher Laufzeit erfordern ein detailliertes Verständnis dieses tribologischen Kontaktes. Aus diesem Grund ist es erforderlich, unterschiedliche Kolb...
