Low-Pressure In-Cylinder Fuel Injection
SAE Technical Paper Series, 2003<div class="htmlview paragraph">The Idaho State University design team, competing in the 2003 Clean Snowmobile Challenge Collegiate Design Competition, has developed a strategy to reduce the amount of harmful emissions common to two-stroke snowmobiles. The team designed a Low Pressure In-Cylinder Fuel Injection system to reduce the amount of fuel

Applicability of Pneumatic Cylinders in Low-Pressure Water Hydraulics
SAE Technical Paper Series, 2000<div class="htmlview paragraph">Low-pressure water hydraulics (LPWH) is a new field of fluid power technology. LPWH-technology uses tap water as a pressure medium and maximum working pressure is under 50 bar (725 psi). This technique enables better motion control and larger forces than pneumatics.

A low-pressure high-temperature technique for the piston-cylinder
American Mineralogist, 2008A method for conducting successful low pressure (0.3‐0.5 GPa) and high temperature (900‐1200 °C) experiments in the 19 mm piston-cylinder is presented. The technique is capable of running high fluid/melt experiments with minimum hydrogen loss, attaining precise, reproducible pressures (±10%), and has fast initial quench rates (>150 °C/s).

SAE Technical Paper Series, 2000
<div class="htmlview paragraph">Over the last two decades, advanced engine control systems have been developed that use cylinder pressure as the primary feedback variable. Production application has been limited by cost, reliability, and packaging difficulties associated with intrusive cylinder pressure sensors.

The Application of the Baumann Stage in the Low-Pressure Cylinders of Condensing Turbines
Thermal Engineering, 2019Among the characteristics of the power-generating steam turbines, the specific metal intensity ranks very high. Low-pressure cylinders (LPCs) that use a two-tier Baumann stage have the lowest value of this parameter. The Baumann stage allows a 50% increase in the limit steam passage rate to the condenser without increasing the last-stage blade length ...

Proportional Position Control of Low-Pressure Water Hydraulic Cylinder
SAE Technical Paper Series, 2002<div class="htmlview paragraph">This paper presents briefly some main properties of two proportional valves that are possible to use in low-pressure water hydraulics. The other valve is a commercial water hydraulic proportional valve and other is a modified pneumatic on/off-valve.

Low-friction cell for piston-cylinder high-pressure apparatus
Journal of Geophysical Research, 1975A high-temperature cell has been developed in which a weak salt such as NaCl is used as a pressure medium. This cell exhibits extremely low friction. The behavior of the cell was studied in detail by observing the melting temperature of metals by dta over the range 10–60 kbar and 300°–1400°C.

Failure prediction of low-carbon steel pressure vessel and cylinder models
International Journal of Pressure Vessels and Piping, 1987Abstract The failure loads predicted by failure assessment methods (namely the net-section stress criterion; the EPRI engineering approach for elastic-plastic analysis; the CEGB failure assessment route; the modified R6 curve by Milne for strain hardening; and the failure assessment curve based on J estimation by Ainsworth) have been compared with ...

Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2021
Wind loads on a surface-mounted finite-height circular cylinder are strongly influenced by the flow field structure. Based on the stationary and moving downburst flows simulated by an impinging jet device, this paper studies the wind pressure distribution in a circular cylinder with a low aspect ratio of AR = 2 at different radial positions and ...

A low pressure alarm device for medical oxygen cylinders: a description of a prototype
7th International Conference on Appropriate Healthcare Technologies for Developing Countries, 2012This paper presents the design and evaluation of an oxygen low-pressure alarm for use in conjunction with medical oxygen cylinders. Patients, who are dependent on oxygen supply through portable, high pressure oxygen cylinders, rely on staff vigilance to ensure that the volume of oxygen in the cylinder does not drop below a critical level, thereby ...
