The Free Piston Engine is a combination of reciprocating engine and rotary turbine. It is called free piston engine because the freedom motion for Mechanical linkage which gives variable stroke according to load.

ADVANTAGES

1. Mechanical simplicity
2. Less power to weight ratio
3. Lower turbine operating tempeatures
4. Multi fuel capability
5. Flexibility and reliability
6. Easy starting and control
LIMITATIONS
1. Poor fuel economic
2. Less stability
3. Poor part load efficiency
4. High combustine rates
5. Reduction gearing

Abstract
Homogeneous charge compression ignition (HCCI) is a form of internal combustion in which well-mixed fuel and oxidizer (typically air) are compressed to the point of auto-ignition. Homogeneous charge compression ignition (HCCI) engines have
the potential for high efficiencies and low pollutant emissions.By comparison with spark ignition (SI) engines, for example,HCCI engines can yield a 15-20% increase in fuel economy while emitting lower levels of oxides of nitrogen (NOx).HCCI engines can also achieve thermal eff ....etc

abstract
An opposed-piston hydraulic free piston engine operating with homogenous charge compression ignition (HCCI) combustion, has been proposed by State Key Laboratory of Engines as a means of significantly improving the IC engine’s cycle thermal efficiency and lowering exhaust emissions. Single and multi-zone Chemkin model with detailed chemical kinetics, and unique piston dynamics extracted from one dimensional gas dynamic model, have been used to analyze the combustion characteristics and engine performance. Intake heating, va ....etc

A review of free-piston engine history and applications


Introduction
Extensive use of fossil fuels as an energy source
for both sea and land based transport leads to sig-
nificant amounts of CO2 and other pollutants be-
ing produced. Much research, particularly within
the automotive industry, is being undertaken to de-
velop more environmental friendly fuel chains, and
the fuel cell vehicle stands out as a promising tech-
nology for the future.

ME Engines “ the New Generation of Diesel Engines

INTRODUCTION

The introduction of the electronically controlled camshaft-less low speed diesel engines, which is now gaining momentum, is a milestone in diesel technology that deserves a place in history like Rudolf Dieselâ„¢s first engine in Augsburg, the 1912 motor vessel Selandia, the introduction of turbocharging on two-stroke diesels in 1954, and the first SCR (Selective Catalytic NOx Reduction) systems on ships in 1989. This paper will outline how MA ....etc
