In automated packing or assembly it is often necessary to bring randomly oriented parts into uniform alignment. Mechanical methods such as vibratory bowl feeders are often used for this purpose, although there is no theory for the systematic design of such feeders. A slanted “fence” attached to the stationary sides of a conveyor belt is also capable of orienting a stream of parts and a sequence...

The engine piston is subjected to very high temperature during the combustion process, and it difficult control stability of geometry at elevated temperature. was analysed by finite element method with steady-state conditions for three different types approach it, where influence alloying aluminum piston, surface coating, its impact on thickness variation followed holes coating have been in det...

Two and three-dimensional test cases were simulated using a detailed kinetic mechanism for methane combustion as a subset for di-methyl ether. A generic piston-bowl assembly for the compression and expansion strokes is utilized at 1500 RPM. A fine grid was used for the 2-D simulations and a rather coarse grid was used for the 3-D calculations together with a k-ε subgrid-scale turbulence model a...

Abstract Tightening noose on engine emission norms compelled manufacturers globally to design engines with low specially NO x and soot without compromising their performance. Amongst various parameters, shape of piston bowls, injection pressure nozzle diameter are known have significant influence over the thermal performance emanating from engine. This paper investigates combined effect fuel pa...

This paper presents the assessment of different piston head geometry made aluminum and magnesium alloy. ANSYS finite element analysis is used to analyze under static transient conditions. Round flat constructed using SOLIDWORK software exported WORKBENCH. According analysis, it found that produced higher stress compared with round piston. Similar trend observed when conducted where capable prod...

This paper analyzes GATI' and its dispute settlement procedure (DSP) in the context of a supergame model of international trade featuring both explicit and implicit agreements. An explicit agreement, such as OAT!', may be violated at some positive cost in addition to retaliatory actions that might be induced by the violation. We interpret this cost as arising from 'international obligation," a ...

A dynamic model of a free liquid piston that exploits piston geometry to produce a high inertance was developed for use in a free piston engine compressor. It is shown that for the size scale targeted, advantageous piston dynamics can be achieved with a reduced piston mass compared to a rigid piston design. It is also shown that the viscous losses associated with the liquid piston are negligibl...
