Özet
Apart from this, the rhombic drive possessed several other valuable features which is listed also in the chapter 5. For example, axial movement of piston rods and absence of lateral forces, permitting good sealing of cylinder ; piston forces can now be compensated by a small buffer space and the crankcase can be at atmospheric pressure. The whole crankcase can men be much lighter and high working pressures possible giving a higher specific power. The rhombic drive formed the mechanical basis often different Philips engines which are presented in mis chapter 5 as well. In the other chapter 6, straight plate Stirling engine, displacer mechanism of the continuous and discontinuous motion had been presented. In addition to this, a prototype of straight plate Stirling engine was projected by Prof. I. Kolin at Zagrep University, was also tried to explain. It has been quite closed to the theoretical cycle as this kind of system was chosen. Because, at the Stirling engine which has a normal piston, the closed area which is obtained by sinusoidal motion of the piston is smaller according to the theory. Because of this, the corner of the closed area have been rolled evidently as well. In practice the closed area can be 5 times smaller than the theory. In this straight plate Stirling engine, if driving board is slightly pushed to the hot or cold board, dead volume between both boards' surfaces decreases. So dead volume is only contact surfaces. In other words, closed area limited by the curves is extended. Because, distance between both isotherm curves increases. Small stationary Stirling engine design had been presented in the chapter 7. A systematic exploration of available general design approaches is made. Principles are formulated to adapt mechanisms from one engine type to another. Several examples of mechanical drive systems are presented in which various aspects of the general discussion are illuminated. In small size, many hold that the stationary Stirling engine has a definite commercial future. In addition to various specialized applications, the need persists for a solid fuel tired Stirling engine of about 1 kW output for use by developing countries, especially for irrigation water pumping, but readly adaptable to a variety of other chores as well. The foremost characteristic for such an engine is simplicity, which would permit field repair and perhaps partial manufacture in the country of end use. The natural choice of working fluid is air at atmospheric or moderately elevated pressure. Output via a rotary shaft would be most suitable for general purpose use. At the conceptual level, the design task for such a Stirling engine can be viewed as the union of thermodynamic and a mechanical design. In the former, one explores and optimizes parameters such as bore, stroke, pressure level, and heat exchanger configurations. The result is a determination of the work space side of the engine.

the kinematic air Stirling engine will be systematically explored, this not only serves to identify options for general engine types, but also yields principles which allow the adaptation of mechanisms from one engine type to the another. Secondly, a number of specific possible mechanical drive systems will be described. Some are tape drive and the inclined yoke drive. The criterion for inclusion here is some measure of practicality or commercial advantage. Available space limits examples to displacer type engines ; this type shows more advantages for the small air engine than does the two piston type. The former tend to be more compact, better suited for annular heat exchangers, and require only one piston seal. In the last chapter 8, conclusions and suggestions had been stated.
