A long-stroke, low-speed marine engine is used as the prime mover of a ship. During operation such engines, excessive wear cylinder liners and piston rings frequently occurs. The breakdown or very dangerous for safety vessel, environment, people on board. reliability components an extremely important topic, it influences efficient vessel. Therefore, to prevent undesired events, essential that c...

We study the Casimir force in piston-like geometries semiclassically. The force on the piston is finite and physical, but to leading semiclassical approximation depends strongly on the shape of the surrounding cavity. Whereas this force is attractive for pistons in a parallelepiped with flat cylinder head, for which the semiclassical approximation by periodic orbits is exact, this approximation...

In this paper we study the Casimir force for a piston configuration in R 3 with one dimension being slightly curved and the other two infinite. We work for two different cases with this setup. In the first, the piston is " free to move " along a transverse dimension to the curved one and in the other case the piston " moves " along the curved one. We find that the Casimir force has opposite sig...

Through the background handover stage and receive piston engine ring component conducted by PT. Toyota Manufacturing Motor Indonesia (TMMI) there are wasteful activities or do not have added value. Then part of way to eliminate waste in activity accept is just time (JIT), then later will be eliminated stages. this research has aim analyze implementation Just In Time influence itself on these co...

This paper presents a new JDtthematieal model of indicated horsepower of rolling piston compressor. It is not an intergul formula but a genertl mathematical formula made out by authors calculating ia detail on the baee of former integral formula of indicated hor1epower aad parameters such as the ratio of Ieath aad diameter, the ratio of eccentric from implicit function. Ia accordance with this ...

− A new controlled-clearance pressure balance has been developed to improve the hydraulic pressure standard for pressures up to 1 GPa. For several controlledclearance piston-cylinders, characterization experiments based on the Heydemann-Welch model were performed to estimate the effective area of them. The results for the piston-cylinders of different pressure ranges are exemplified in this pap...

We consider a massive inelastic piston, whose opposite faces have different coefficients of restitution, moving under the action of an infinitely dilute gas of hard disks maintained at a fixed temperature. The dynamics of the piston is Markovian and obeys a continuous Master Equation: however, the asymmetry of restitution coefficients induces a violation of detailed balance and a net drift of t...
