Heat Release Analysis of Hydraulic Free Piston Diesel Engine

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 ...

Dynamics and Control of a Free-Piston Diesel Engine

Free-piston diesel engines are characterized by freely moving pistons without any crankshaft or camshaft connected to the pistons. This allows a compact and efficient engine design, but requires automatic control of the piston motion. This paper present a dynamic mathematical model of a free-piston diesel engine, and a control oriented dynamic analysis leading to a piston motion control structu...

The control of an opposed hydraulic free piston engine

An opposed hydraulic free piston engine is under design at the Tianjin University in China because of the advantages of this engine compared to the conventional engine. The main challenges presented by such engines are the control of the piston motion and synchronization. This study investigates the fundamental control context and control method of the opposed hydraulic free piston engine using...
