By fixing pistons of different diameters with 6 gripping nails, we clarified deformation of piston rings and stress during tightening by simulation based on the finite element method (FEM) as part of development of a universal holding mechanism to insert it into the cylinder block automatically. Nonlinear FEM was used to analyze slidingat contact parts between the ring and the gripping nail when fastening the piston ring. Final defohnation of the piston ring and stress on different parts were verified in detail. We confirmed that insertion of the piston by this method is possible.

In tribological system of internal combustion engine, cylinders and pistons were in high temperature, pressure and load working status. An SRV IV wear tester was used to measure dynamic coefficient of friction by simulating working condition of cylinder liner and piston ring. The worn surface topography was observed through scanning electron microscope and metallography. The results show that loads had little effect on the friction coefficient under oil lubrication. Cylinder with the high-chromium carburizing ring in pairs displayed wear in the form of plastic deformation, while cylinder with

The engine consists of a large number of parts, each of which is responsible for a specific function of its efficient operation. The reliability of a marine diesel engine is largely determined by the resource of its individual components and parts. Therefore, in order to increase the engine life, it is necessary to allocate the most responsible parts in it, which are subject to greater wear and find solutions to increase their durability. Such details include piston rings, which affect not only the technical and economic performance of the engine, but also its reliability and environmental per

The vast majority of high-speed engines are equipped with aluminum alloy pistons, and since these engines occupy a leading position in shipbuilding, the issue of restoring the piston as the most stressed and wear-prone part is relevant today. Aluminum alloy has a large number of positive qualities that determine their use for high-speed engines. These include low weight, which is necessary to reduce inertial loads, high thermal conductivity, due to which the piston does not overheat during normal operation, and a low coefficient of friction. But for all the advantages of an aluminum alloy, it

During the engine operation, the piston rings wear out and the grooves under the piston rings are destroyed, as a result of which there is a decrease in the sealing of the combustion chamber. This problem has been usually solved by replacing the old, spent piston and rings with new ones. There is considered a method of extending the life of the cylinder piston group. The proposed method consists in changing the composition and design of the upper piston ring, which is primarily responsible for sealing the combustion chamber.

Purpose Currently, lubrication analysis of piston ring is generally done under engine rated operating condition. However, the engine (such as the vehicle engine) does not always operate in rated operating condition, and its operating condition changes frequently in actual use. In addition, the lubrication status of piston ring is generally assumed as the flooded lubrication or a certain form of poor lubrication in most of the lubrication analysis.

The interface between the piston, piston-rings and the cylinder liner represents one of the most hostile environments the crankcase lubricant experiences in reciprocating engines. The role of piston rings is also becoming more complex in line with the increasing requirements for lower oil consumption and friction. A test rig has been developed to simulate under idealised conditions the lubrication action between the piston-ring and the cylinder-liner in reciprocating engines.

The compression and oil rings of the piston engine play a very important role in the performance and reliability of the piston engine. The rings are required to accomplish three main distinct tasks: 1. Sealing the combustion chamber gas from the crankcase to eliminate blow-by phenomenon, which constitutes the flow of some of the contents of the combustion chamber into the crankcase. 2. Proper distribution of the lubricating oil film over the piston skirt and cylinder liner. 3. Transfer of heat from piston to cylinder liner.

The automotive industry is subjected to increasing pressure in order to improve fuel efficiency and reduce the CO2 emissions of internal combustion (IC) engines. The power cylinder system (piston, piston ring, and liner) contributes significantly to the friction losses, engine oil consumption and gas leakage called blow-by. The role of cylinder bore shape in engine performance has been the subject of several studies in recent years. High bore distortion must be avoided because it can lead to ring conformability issues, which leads to inadequate sealing resulting in increased blow-by and oil co

The influence of piston ring lubrication on internal combustion engine performance has received considerable attention for over half-century. Studies show that hydrodynamic lubrication prevails through most of engine cycles, and asperity contact only occurs near the vicinity of dead centers [1][2]. In order to solve the governing equation of lubricant, appropriate velocity and pressure boundary conditions should be incorporated into the lubrication equation - Reynolds equation. While lubricant obeys the no-slip velocity boundary condition, the pressure boundaries at the leading and trail edge

These factors are highly influenced by the power cylinder system design. In particular, the piston ring to cylinder bore contact force distribution around the circumference of the piston rings must be optimized under all running conditions. To accomplish this, the ring manufacturers make the ring curvature non-constant along the circumference. Most existing analytical tools are not able to simulate the variation al

Resumo:
A timed lube oil injection system was developed for a field engine to improve power cylinder lubrication. The injection system used advanced prototype electronic injectors. The system was installed on a Cooper GMVA-10 located in West Virginia. A total of four cylinders were included in the study, two for the timed system and two for the baseline mechanical system. Cylinder wall lubrication, cylinder wear, piston wear, and ring wear tests were planned for various engine run times. The prototype timed lube oil system operated essentially until the prototype injector end-of-life was reached at ab

Resumo:
A retrofit lube oil injection system is designed with the capability of injecting oil through two lube ports on each cylinder at any time during the engine cycle. The system is installed and tested on a Cooper-Bessemer GMV4 engine. Variations in number of skip cycles, average lube rate, and injection timing are evaluated. Lube oil carry-over is quantified using a dilution tunnel and a standard particulate matter gravimetric measurement technique. Cylinder wall lubrication is quantified using a custom designed fixture that is inserted into the fuel valve port between data points when the engine
