Empirical metod of predicting aviation piston engine noise

Analysis of Piston of Two Stroke Engine

Due to the inherent nature of combustion in the Cylinder of a Conventional Internal combustion engine, stress variation as well as a certain temperature distribution sets up in the entire piston. Analysis of piston is required because of its shape and it is subjected to both structural and thermal loads. In the present study, piston of a two stroke spark ignition internal combustion engine havi...

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 ...

A 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...

Experimental study of piston scuffing effect on engine performance parameters

Piston scuffing is one of the destructive faults in internal combustion (IC) engines. There are different causes to make this fault that lack of lubricant is the most important one among them. The purpose of this paper is the quantitative study of the piston scuffing effects on the engine performance parameters which is a new research direction in the IC engine filed. For this reason, several e...
