“…The effects of tests obtained using a real engine powered by an electric motor are better and similar to those of a fired engine than those obtained from reciprocating sliding. In [ 101 , 102 , 103 ], it was found that cavities of a large depth (0.2–0.3 mm) on the liner surface led to less wear, a tendency to scuff, and a coefficient of friction than on the untextured surface. Yin et al [ 104 ] recommended a square dimple array with a tribological behavior was better than the stagger array when rows of dimples were shifted.…”

“…Peng and Huang [ 102 ] powered the real engine with an electric motor to ensure conditions similar to those of the real engine. Cylinder liner B had grooves of comparatively high depth (0.3 mm, width 3 mm), cylinder liner C had isolated dimples of similar depth and diameter of 1 mm, while cylinder liner D had a combination of grooves and dimples ( Figure 12 ).…”

The effect of cylinder liners on engine performance is substantial. Typically, the cylinder surfaces were plateau honed. However, recently additional dimples or grooves were created on them. This work discusses the tribological impacts of textured cylinder liner surfaces based on a review of the literature. The results of the experimental research obtained using test rigs and fired engines were critically reviewed. In addition, the results of the modeling are shown. Circular oil pockets and grooves perpendicular to the sliding direction of piston rings of small depths were typically used. Surface texturing of the cylinder liners governs lubrication between the cylinder liner and the piston ring by an increase in oil film thickness near the reversal points leading to reductions in friction force and wear and in the fired engine to a decrease in fuel consumption and to an increase in power or torque. The correct texturing pattern ensures a decrease in the oil consumption, blow-by, and emissions of the internal combustion engine compared to plateau-honed surfaces. Considerations of future challenges are also addressed. The volume of lubricant reservoir in surface topography, called oil capacity, should be a substantial parameter characterizing textured surfaces.

“…The cylinder liner internal surfaces were processed with five TGT of different depths (50,100,150,200 and 250 mm) by ultraprecision machining technology, which are symmetrically distributed on the internal surface. The width of TGT is 3 mm, with surface occupancy of approximately 12.63 per cent (Wang et al, 2018;Peng and Huang, 2018); see Figure 1.…”

Purpose Frictions in cylinder liner-piston ring often cause an inevitable loss of energy loss in the diesel engine. This study aims at evaluating the effect of depths in the cylinder liner groove texture on friction, wear and sealing performances. Design/methodology/approach Five depths of groove texture cylinder liners (50, 100, 150, 200, 250 µm) were fabricated, and experiments were carried out using a special-purpose diesel engine tester. Comparative analyses of cylinder liner contact resistances, piston ring wear losses and surface appearances were conducted with respect to different surface textures and applied loads. Findings Under no-load conditions, the cylinder liner with a 100 deep thread groove can significantly improve sealing and optimize its lubrication performance. On the other hand, the sealing is highly correlated with the depth of groove and the load within the cylinder liner. Under loaded conditions, the thread groove has less effect on the sealing performance. Originality/value The findings can provide feasible basis for the tribological design and production of diesel engines.

“…The friction and wear performance can improve via the surface texturing method. [1][2][3] For example, Costa et al 4 pointed out that surface textures hold great potential to enhance the frictional performance of tribological systems. Marian et al 5 used numerical approaches to optimize the micro-textures to further improve tribological properties of the textured surface.…”

PTFE-filled textured surfaces were impregnated with the dopamine dipping solution to improve their tribological performances. Ball-on-disc wear experiments were conducted to compare tribological properties of three surfaces: the textured surface, filled textured surface and modified filled textured surface. The worn surfaces, wear debris, and shedding areas of the PTFE were measured, and shear strength between the PTFE block and medium carbon steel after impregnation modification was analysed. Experimental results showed that compared with textured surfaces, filled textured surfaces and modified filled textured surfaces had lower friction coefficient values and cross-sectional areas of wear scars. Compared with the filled textured surface, the modified filled textured surface reduces filled gaps by 63.5% and the shedding ratio of the PTFE within dimples by 63.2%. The research results demonstrate that tribological performances of the filled textured surface can improve after impregnation modification. Polydopamine can react to covalent-noncovalent interaction with PTFE and medium carbon steel. Polydopamine acts as a binder to improve the bonding strength between the PTFE and the inner wall of dimples. Polydopamine can reduce the shedding ratio of the PTFE and maintain the antifriction function of the PTFE in dimples.
