Commercially available cylinder liner and piston rings of the tractor 85HP were collected and cut into small samples.
Compared with the L-Standard piston, the contact pressure at the lip part of the L-Sl piston increased, the gap between the piston and cylinder liner became small, which could effectively prevent abrasive particles from participating in the wear and resulting in piston failure, and there was greater improvement in the service life of piston.
As a different approach, the numerical simulation based on finite element method (FEM) is very useful to predict the three-dimensional distortions of cylinder liner. These approaches take into account pretightening force, heat transfer, and complicated combustion process which the above analytical models neglect.
This style of hone smoothes out all of the rough spots around the ports or any other part of the cylinder liner walls - top to bottom."
The result from the literature survey however suggests a possibility of using textures also for the control of the viscous friction losses and a hypothesis tested in this study was formulated based on the assumption that a texture with a valley geometry larger both laterally and vertically than previously reported traditional cylinder liner concepts would constitute a texture able to decrease the hydrodynamic friction losses.
The cylinder liner is positioned within the facility and the air supply duct is attached to the top of the cylinder liner.
What's different is a rotating cylinder liner that serves as the respiratory gatekeeper, replacing the complex train of valves found in a four-cycle machine.
Cavitation erosion is the result of the repeated formation and collapse of bubbles in the coolant at the walls of an engine cylinder liner. The collapse of these bubbles at a rate of 20 times per second (for 1200 rpm) with force of as much as 100,000 psi causes a water hammer effect on the cylinder liner which, over time, will eventually lead to perforation of the liner and leakage of coolant into the piston cylinder.
