Coupled dynamic–multidimensional modelling of free-piston engine combustion. ⋆
Free-piston engines are under investigation by a number of research groups worldwide, as an alternative to conventional technology in applications such as electric and hydraulic power generation. The piston dynamics of the freepiston engine differ significantly from those of conventional engines, and this may influence in-cylinder gas motion, combustion and emissions formation. Due to the compl...
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...
متن کاملPredictive piston motion control in a free-piston internal combustion engineI
A piston motion controller for a free-piston internal combustion engine is presented. To improve dynamic performance in the control of the piston motion and engine compression ratio, the controller response is determined from a prediction of engine top dead centre error rather than the measured value from the previous cycle. The proposed control approach showed superior performance compared wit...
متن کاملFree-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...
