I also declare that, as required by these rules and conduct, I have fully cited and referenced all material and results that are not original to this work.

Altan Kayran Septemberpages A novel turbo rotary engine, operating according to a novel thermodynamic cycle, having an efficient compression phase, a limited temperature combustion phase followed by a long power extraction phase is designed. Thermodynamic and structural design and analysis of this novel engine is carried out and two prototypes are manufactured according to these analysis.

High performance figures such as torque, power and low specific fuel consumption are calculated. Also the component tests of the manufactured prototypes are completed and their results are demonstrated.

Despite this Externalinternal factors essay, for many years, patents on rotary combustion engines [2,3,4,5,6] have claimed that rotary engines possess many advantages over reciprocating engines such as having high torque, fewer parts, lower weight and fewer reciprocating imbalance.

Early rotary compressor designs had low volumetric efficiencies, undesirable high delivery air temperatures due to internal air leakage and considerable blade and cylinder wear due to lack of adequate lubrication [1].

These disadvantages have all been addressed in this thesis. In this thesis, an engine compressor with a volumetric efficiency of Further, the longer compression stroke rotation angle enhances the fuel-air mixing as fuel is injected by a carburetor alongside the air intake phase.

The fuel evaporates in the compression phase and helps lower the compression temperature which further decreases the required shaft power input to the rotary compressor.

A good fuel-air mixing permits leaner combustion to occur in the external burner which is placed downstream of the compressor.

As less fuel input is needed to reach allowable turbine inlet temperature, the specific fuel consumption is favorably decreased. Air and oil cooled sliding vane engine have additional very desirable features such as nearly steady air flow processing, small pressure fluctuations, low noise levels and smooth running characteristics.

Another objective of this thesis is to increase the overall thermal efficiency above levels reached by today s heat engines. This is achieved by adopting a novel thermodynamic cycle which allows a longer power extraction phase. The designed rotary vane engine also achieves high compression ratios with less shaft power input as air is processed through a smooth crescent shape constriction which progressively squeezes out the fluid to the combustion chamber.

As maximum peak temperature is limited, the operational and maintenance costs are also minimized. All together, in the presented thesis, an efficient, powerful, compact, simple and reliable heat engine is designed, analyzed, manufactured and tested.

In internal combustion engines, as distinct from external combustion engines, this energy is released by burning or oxidizing the fuel inside the engine. The fuel air mixture before the combustion, and the burned products after combustion are the actual working fluids.

The work transfers which provide the desired power output occur directly between these working fluids and the mechanical components of the engine.

The spark ignition engines sometimes called Otto engines or gasoline enginescompression ignition or diesel engines are the main internal combustion engines. It is the fact that combustion takes place inside the work producing part of these engines that makes their design and operating characteristics fundamentally different from those of other types of engines.

Practical heat engines have served mankind for over two and a half centuries.Internal And External Factors Paper Essay Sample. The four functions of management are planning, organizing, leading, and controlling.

Planning occurs within these functions of a business, and it helps to deliver strategic value. 96) In addition.

External and Internal Factors The purpose of this paper is to compare the internal and external factors that influence a company, considering the aspects of the business process including globalization, technology, innovation, diversity, and ethics.
