...Xiaofeng He; Wei Huang; Bihai Zhu; Liang Luo The purpose of this paper is to investigate the air suction characteristics of a water hydraulic piston pump with check valves. The influence of some factors on its air suction performance, including compression ratio, initial spring forces, valve gaps...

...Andrea E. Catania; Alessandro Ferrari An experimental-theoretical study has been carried out on high-pressure volumetric radial-piston pumps for diesel fuel injection systems. The dependence of the pump inducted flow rate on speed and load was investigated and the characteristic curve of the pump...

... and shock formation, which are difficult to accurately capture with numerical simulations, particularly when the combustion chamber geometry is complex and the piston and intake/exhaust valve grids are moving. In this paper, a three-dimensional moving grid model of the combustion engine chamber, originally...

...Shu Wang This paper discusses and analyzes the control volume of a piston bore constrained by the valve plate in axial piston pumps. The vacuum within the piston bore caused by the rise volume needs to be compensated by the flow; otherwise, the low pressure may cause the cavitations and aerations...

...I. da S. Rêgo; T. Ando; K. Misumi; T. Miyazaki; S. Nishiyori; K. N. Sato; M. Sakamoto; S. Kawasaki A double piston-actuated structure designed for replacing the use of diaphragms in conventional shock tubes has been recently developed. In order to clarify the piston sliding process...

... of the fuel delivered by the injector. The paper presents a study, at both a macroscopic and microscopic level, of a Diesel spray generated by a common-rail injection system featuring a piston pressure amplifier. By modifying the timing and the duration of the injector and amplifier piston actuation...

... Reynolds number turbulence with very low mean velocity is generated by an array of spinning grids. Planar straining and destraining mean flows are produced by pushing and pulling a rectangular piston towards and away from the bottom wall of the tank. The velocity distributions are processed to yield...
