| Summary: | A new arrangement of the engine is introduced where the cylinder revolves around the hinged structure to let the normal force be exerted on the connecting rod. It is proven that in this case, up to 26.3 % extra force can be obtained compared to a conventional design. In this design, constant maintenance such as lubrication, cooling due to intensive friction, and piston-cylinder sealing is reduced. When the cylinder is hinged, it runs more smoothly, and under the same 1 bar input pressure, the engine speed is 60 rpm more than that of an engine in the conventional configuration. This demonstrates the efficiency of the hinged-cylinder configuration. The consolidated connecting rod/piston assembly in a freely revolving cylindrical duct has a DOF = 2, showing the design's full practical potential. To prove the validity of the proposed power system, the multibody dynamic simulation of assembly is implemented in ADAMS, which again confirms higher force applied to the shaft (Fhinged ≈ 7.5 kN > Ffixed ≈ 1.28 kN). |
