“…It is well known that the contact cylinder liner - piston ring susceptible to friction and wear, mostly related to ring load and temperature, work period and sliding speed, nevertheless it is very hard to expect the physical effect of this parameter with realistic values, for this reason, Julian Biberger et al. [9] used rotational tribometer with a novel testing method to perform friction and wear at a different level of pressure combustion chamber, ring temperatures and sliding speeds, they observed that for a small load, friction declines intensely when increasing sliding speed and wear rises for lesser temperature, whereas it decreases with greater temperature. Enhancing the surface conditions with the fine finish and surface treatment together with tighter tolerances implementation are essential to ensure better lubrication conditions, less friction, low wear and consequently good sealing effect between the cylinder wall and piston rings that leads to high engine efficiency, and longer service life span [13, 14].…”

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.

“…Beside a close-to-application specimen production, details of the test rig and the test procedure can be crucial for the correct transfer of the application results. For example Biberger et al implement a lubrication system with a very low flow rate for their ring/liner model tester, to match the deficient lubrication situation of the top piston ring [18]. The heating of the piston group with combustion gases is simulated by Johansson et al with a heat gun combined with a water cooling system for the liner [3].…”

Physical simulations of tribo contacts in internal combustion engines can act as a supporting tool to match upcoming guidelines and emission restrictions. In particular, the scuffing resistance of the contact between the piston ring and cylinder liner suffers under decreasing oil viscosity and limitation of antiwear additives. This paper aims to provide an experimental method to simulate the scuffing of the piston ring/cylinder liner-contact and to validate this method with real engine parts and the literature from engine tests. The experimental methodology uses a linear tribometer TE77 to test specimens from original piston rings and liners under reciprocating motion. Additionally, the ring specimen is given the opportunity to perform secondary movements (ring twisting, ring turning) and to run under deficient lubrication conditions similar to the engine. A specially designed test strategy enables the reproducible creation of seizure of the tribosystem. The seizure resistance of two engine oils, tested for validation, correlates with the known engine performance. Therefore, the model test system can be seen as a reproducible tool for simulating seizure of a ring/liner-system, showing similar trends and wear mechanisms as in an engine. Surface analysis depicts similarities between the scuffed surfaces of an engine and the model and discusses the origin of seizure based on the model specimens together with the relevant literature.

Cylindrical liner is the place of burning to generate power or effort inside the Mother Machine. The size of the oversized diameter will affect the incomplete combustion. The purpose of this study was to determine the causes of broken piston rings and surging, the impact of oversized liners and strategies to minimize the impact of oversized cylinder liners. The research method used is SWOT analysis and questionnaire method distributed to 51 samples of students officer of ATT II class and on board interview. Oversized cylinder liner causes the piston ring to be broken and incomplete combustion causing surging turbocharger. Strategies to minimize the impact of oversized liner by replacing piston rings and cylinder liner, cleaning scavenging of water thrunk and piston groove for normal rinse air pressure and combustion quality increases
