Free-Piston Diesel Engine Dynamics and Control
Free-piston diesel engines are characterized by freely moving pistons without any rigid crankshaft or camshaft connected to the pistons. This allows a highly compact and e cient engine design, but requires automatic control of the piston motion. This paper present a dynamic mathematical model of a free-piston diesel engine, a control oriented dynamic analysis, and a novel computer-based piston ...
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 کاملPerformance simulation of a spark ignited free-piston engine
Free-piston engines are under investigation by a number of research groups worldwide due to potential fuel efficiency and engine emissions advantages. The free-piston engine generator, in which a linear electric generator is fixed to the mover to produce electric power, has been proposed as an alternative prime mover for hybrid-electric vehicles. This paper investigates the performance of a spa...
متن کاملModeling 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 کاملAnalysis of Tubular-type Linear Generator for Free-Piston Engine
Tubular-type linear generator for the free-piston engine is anlayzed using finite element method and its characteristics are explaind. Magnetic characteristics of the linear generator are calculated using the finite element method and various structures are considered to achieve the lowest detent force within the rated voltage. The path of the magnetic flux is constructed by the axially magneti...
