Magnetorheological (MR) materials are a group of smart used in new technologies with controlled reliability. The development these is expanding, starting from MR fluids, elastomers, grease, and gel. This large number material types further expands the various applications as creative technology to support performance enhancement. For example, fluid improve shock absorbers such vehicle suspensio...

Abstract The highest loads on the elements of crank–piston system internal combustion engine occur during phase which takes place successively in individual cylinders. Smaller, but also significant, beyond this when dynamic forces begin to play a dominant role. latter depends degree wear components. aim article was analyze stresses model stand for testing phenomena an operating without process....

It is hypothesized that female-male mounting is an adaptive behaviour, functioning to prompt sluggish males to mount females in return. This hypothesis has been proposed many times and independently by different authors, however it had yet to be tested. Furthermore, the proximate mechanisms that drive the behaviour, specifically the male and female movements and actions that prompt its occurren...

in this study the performance and emissions characteristics of a heavy-duty, direct injection, compression ignition (ci) engine which is specialized in agriculture, have been investigated experimentally. for this aim, the influence of injection timing, load, engine speed on power, brake specific fuel consumption (bsfc), peak pressure (pp), nitrogen oxides (nox), carbon dioxide (co2), carbon mon...

nowadays, due to the increasing power of diesel engines, especially heavy duty diesel engines, and increasing gas pressure inside the combustion chamber, the forces acting on the engine bearings have dramatically raised. on the other hand, becaus eof the competition in the market, it is necessary to increase the engine bearing life and reduce its failure as much as possible. the engine bearings...
