Modeling and Control of a Free Liquid-Piston Engine Compressor
This paper presents the modeling and control of a prototype compact free liquid-piston engine compressor. The dynamic model includes 1) the injection dynamics of the air/fuel mixture, 2) the dynamics of heat release during combustion, 3) the inertial dynamics of the magnetically latched combustion valve, 4) the mass flow dynamics of the combustion and exhaust valves, 5) the inertial dynamics of...
متن کاملReducing Piston Mass in a Free Piston Engine Compressor by Exploiting the Inertance of a Liquid Piston
A dynamic model of a free liquid piston that exploits piston geometry to produce a high inertance was developed for use in a free piston engine compressor. It is shown that for the size scale targeted, advantageous piston dynamics can be achieved with a reduced piston mass compared to a rigid piston design. It is also shown that the viscous losses associated with the liquid piston are negligibl...
متن کاملA miniature free-piston engine/compressor
Portable powered devices such as construction tools and orthotics require a power supply that is light and compact. Hydrocarbon fuel has exceptionally high energy density compared to batteries but must be converted to mechanical power to be useful. We designed, constructed and evaluated a tiny internal combustion air compressor that uses a free-piston configuration combined with homogeneous cha...
متن کاملLiquid piston gas compression
A liquid piston concept is proposed to improve the efficiency of gas compression and expansion. Because a liquid can conform to an irregular chamber volume, the surface area to volume ratio in the gas chamber can be maximized using a liquid piston. This creates near-isothermal operation, which minimizes energy lost to heat generation. A liquid piston eliminates gas leakage and replaces sliding ...
متن کاملDesign and Analysis of a Resonating Free Liquid-piston Engine Compressor
This paper presents the design and simulation of a resonating free liquid-piston compressor (FLPC) equipped with a separated combustion chamber. The FLPC is a proposed device that utilizes combustion of a hydrocarbon fuel to compress air into a high-pressure supply tank, thus potentially serving as a portable power supply candidate for untethered pneumatic systems of human-scale power. The ener...
