Analysis and experiment show that to supercharge the suction volume of a cylinder by means of pressure pulsation is not certain to result in delay of the valve closing. To arrange a proper suction pipeline and valve cavity, we can not only get supercharge of the cylinder, but also,get economical specific power consumption, while valve working condition is good too. In this paper the methods of ...

Abstract In this work, the pulsation analysis is performed on 83 high-amplitude δ Scuti stars (HADS), which have been observed by Transiting Exoplanet Survey Satellite. The results show that 49 of these HADS single-mode pulsation, 27 them radial double-modes (in 22 pulsate with fundamental and first overtone modes five second modes), seven triple-modes (three are newly confirmed triple-mode HAD...

After a historical introduction, I present the current status of our understanding of the mechanism responsible for pulsation in β Cephei and SPB stars.

We review some of the recent advances in nonlinear pulsation theory, but also insist on some of the major extant shortcomings.

This paper presents a system for compensating DC link current pulsation in four-wire inverters with energy storage operating under unbalanced load conditions. phenomenon occurs when an inverter independent power control each of the phases attempts to locally balance voltage imbalance grid. Such condition creates pulsation, which is destructive connected link. The conditions this situation appea...
