A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas (the working fluid) at different temperatures, such that there is a net conversion of heat energy to mechanical work. More specifically, a closed-cycle regenerative heat engine with a permanently gaseous working fluid.
The Stirling engine is noted for its high efficiency compared to steam engines, quiet operation, and the ease with which it can use almost any heat source.This engine is currently exciting interest as the core component of micro combined heat and power (CHP) units, in which it is more efficient and safer than a comparable steam engine.

The increasing demands for low emissions and low fuel consumption in m odern combustion engines requires improved methods for combustion process. The Beare Head is a new type of six-stroke engine head design known as the �Beare Head� after its designer,Malcolm Beare. T he Beare Head uses a piston and ports very much like a two stroke engine to replace the overhead valve system t hat is found in four stroke engines today. The four-stroke block,piston and crankshaft remain unaltered. This combinat ion of two stroke and four-stroke technology has given the technology its name the �six stroke engi ne�. Six Stroke engine,the name itself indicates a cycle of six strokes out of which two are useful power strokes. According to its mechanical design,the six-stroke engine with external and internal combustion and double fl ow is similar to the actual internal reciprocating combustion engine.
Thermo Structural Analysis on Cylinder Head of 4 Stroke VCR Diesel EngineDr. Amarjeet Singh
The main aim of the project is to analyse the design performance of VCR 4 stroke Diesel engine cylinder head at the compression ratio 16.5 using Ansys software. The basic modelling is done on CATIA V5 software. The design exposition can be done structurally and thermally in ansys. By the structural analysis the maximum and minimum von misses stress, total deformation can be determined, the maximum gas pressure required for this analysis is taken from the experimental set up of VCR engine. With the steady state thermal analysis we will get the maximum temperature distribution and total heat flux of the cylinder head with the initial pressure value. The results of both the expositions are used to decide the critical areas of the cylinder head which require further amendment and also the quality of design. If the maximum stress is less than the material strength of the cylinder head then the basic design criteria can be achieved.

Study of Time Reduction in Manufacturing of Screws Used in Twin Screw PumpIJMERJOURNAL
ABSTRACT: This paper gives the characteristics of Time reduction in manufacturing of screws for Twin screw pumps. Screws are playing a vital role in the performance of pumps, because pumps give the fluids transfer rate with the help of screws. There is a gap in screws which shows its positiveness. This indicates that we are studying about positive displacements pumps. Positive displacements pumps having no point of contact between screws, because of that there will be no any friction formation. Automation is best for development of product to reduce time in manufacturing of any product. In this paper we also tried to explain this feature of Automation to help reduction of time to manufacture of product to increase productivity.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

4. ABSTRACT
Worldwide attempts are being made to increase
the use of our renewable energy sources as well as to use our
current fossil fuel energy sources more efficiently. Waste heat
recovery forms a substantial part of the latter and is the focus
of this project.
The aim of this project was to design, build, and
review of Stirling engine capable of generating power. This
project provided a great opportunity to gain experience with
mechanical design, manufacturing, and the fundamentals of
Stirling engines.
We applied our knowledge of thermodynamics
to the design of the engine, and developed formulas to predict
its power output at different temperature differentials.

6. HISTORY
The Stirling Engine is one
of the hot air engines. It was
invented by Robert Stirling
(1790-1878) and his brother
James. His father was interesting
in engine and he inherited it. He
became a minister of the church at
Scotland in 1816. At this period,
he found the steam engines are
dangerous for the workers. He
decided to improve the design of
an existing air engine. He hope it
wound be safer alternative.

27. The lack of pressurization may also be an opportunity
to improve the engine. Most successful Stirling
engines in our research were pressurized to some
extent. Currently there are leakage issues on the hot
side preventing pressurization, and more may become
apparent as pressure is increased
Several problems remain to be addressed within the
engine. First among them is the overall lack of useful
work output by the engine. Most of the work is being
absorbed by the friction of the crankshaft and piston
linkages, and possibly by inferior bearings. Further
inspection of the compressor block is recommended to
isolate and rectify these problems.
