Performance of a tubular machine driven by an external-combustion free-piston engine

open access: yesThe Journal of Engineering, 2019
Free-piston engines have the potential to offer a compact machine capable of delivering electrical power. In this work, the design and modelling of a linear tubular generator are presented and used to investigate the effect of the electrical machine ...

Simulation of finished and thermal stocks of two-stroke engine piston modified with catalytic material [PDF]

open access: yesОмский научный вестник, 2022
The calculations of the thermal and stress-strain state of the two-stroke gasoline engine (CS5200) pistons are completed. The model of an original piston and a piston modified with catalytic materials is used in the calculations.

Design and optimisation of cushioning structure of hydraulic free-piston engine

open access: yesThe Journal of Engineering, 2018
The velocity of the free-piston assembly (FPA) of the hydraulic free-piston engine (HFPE) is very high, which is up to 10 m/s. In order to avoid the collision of the FPA to the cylinder head when the FPA moves towards the dead centres, the cushioning ...

Heteroatom-Mediated Covalent Organic Framework Membranes With Nitrogen-Enriched Nanochannels for Efficient Desalination. [PDF]

open access: yesAdv Sci (Weinh)
Heteroatom precursor engineering serves as a molecular‐level strategy to tailor hydrazide monomer reactivity and diffusion kinetics, enabling controlled assembly of highly crystalline COF membranes with ultramicroporous channels. The nitrogen‐enriched nanochannels deliver high water/ion selectivity via simultaneous water transport acceleration and ion ...

Piston rotation and frictional forces between piston and cylinder of piston and motor

open access: yesProceedings of the JFPS International Symposium on Fluid Power, 1993
The influence of the piston rotation on the frictional forces between the piston and the cylinder has been studied experimentally for a swash plate type piston pump and motor. In order to measure the rotational speeds of the piston, the capacitance detecting method have been employed for the piston with the slits.
