Effect of cylinder-liner rotation on wear rate: An experimental study

Abstract

In rotating cylinder-piston system, the largest losses source is frictional losses, accounting for 50% of the total frictional losses, thus it is important to optimize. Effect of incremental rotation of a cylinder liner on its wear rate was investigated. The engine speed, load and the cylinder rotating angle were the main parameter. The results showed that the wear rate may be reduced to the half simply by rotating cylinder liner every six hours’ time interval of working. The test was carried out in pairs using a piston cylinder with movable liner and compared to a standard cylinder liner (fixed liner). Angles of 60 o , 120 o , 180 o , 240 o , and 300 o were used for incremental movement. The same operating conditions for two cylinders were maintained for the purpose of comparison. Beneficial effects of reducing the wear rate for all components of the piston-cylinder arrangement associated with incremental rotational movement of a cylinder linear were noticed. A decrease in wear rate was obvious in the cylinder liner in rotation angles of 120 o and 240 o and it is almost one-fourth of the wear that occurs in the stationary cylinder liner.

Experimental study of the tribological characteristics of a honed cylinder liner during the running-in process

“…The surface topography parameters have a significant impact on friction and wear, and the effect of the cylinder liner surface topography on abrasive wear has been studied at different honing settings (Michalski and Wos, 2011). Research on the surface texturing of the cylinder liner has attracted more attention with respect to reducing friction (Babu et al, 2020;Walker et al, 2019), and the wear rates of the cylinder liner have been studied at different engine speeds, loads and cylinder rotation angles (Musmar et al, 2019). Meanwhile, the influence of the lubrication conditions and temperature on wear and friction of the PRCL has been studied using a reciprocating test (Obert et al, 2016).…”

Sliding Wear Behavior of High-Temperature Vacuum-Brazed WC-Co-NiP Functional Composite Coatings

“…Friction and wear are not purely phenomena that can be solely solved by simply selecting a harder material [ 4 , 5 ]. They emerge from the contact interaction between moving parts that is influenced by many factors, such as contact, load, speed [ 6 , 7 , 8 ], surface and base material hardness, elasticity, toughness, chemical reactions [ 9 ], and lubrication [ 10 ], and also the dominant environmental factors, including temperature, humidity, impurities, and radiation [ 3 , 11 , 12 , 13 , 14 , 15 , 16 ]. Some deficiencies causing friction and wear can be addressed rather easily, while others are more complicated to solve.…”
