• thereby when burning fuel oil to produce power is not required, but inputting high pressure gas in a pressure tank to force hydraulic oil in a hydraulic tank, and the hydraulic oil is controlled intermittently by the pressure rotating disc so as to drive the main-cylinder device and the right-side main-crankshaft devices of a right-side operation structure, hence the recycle-valve swing-arm pushes the right-side recycle-valve device and to actuate the hydraulic oil in the right-side main-cylinder device to produce pressure via the right-side recycle-valve device to open automatically the right-side movable-valve device, and when preparing to flow into the right-side recycle-cylinder device, the right-side recycle-crankshaft device, the first central shaft, the umbrella gear set and the right-side umbrella-shaped gear device act to one another so as to drive the drive cam to rotate the operation arm and to close the accelerator of the recycle-cylinder devices, hence oil pressures between the right-side recycle cylinder and the hydraulic tank are isolated to produce zero resistance, in the meantime, the second piston of the recycle cylinder move upward simultaneously so that the hydraulic oil moves into the recycle cylinder in the zero resistance, after the auxiliary crankshaft, the first central shaft, the umbrella gear set, and the second central shaft act to one another, the drive cam is driven to rotate the operation arm so that when the accelerator of the recycle cylinder opens, the recycle cylinder is in communication with the hydraulic tank, and the hydraulic oil in the right-side recycle-cylinder device flows into the hydraulic tank reciprocately, and the related components of a left-side operation structure operate in turn, hence related components of the right-side operation structure operate opposite to those of the left-side operation structure, thus finishing operation of the engine;
• the engine of the present invention forces the hydraulic oil by using the high pressure gas, the hydraulic oil circulates in turn, and the high pressure communicates with the low pressure so as to match with circulation space of fluid operation to produce torque, hence four strokes cycle of intake, compression, combustion and exhaust of conventional engine are not required, and burning fuel oil to produce power source is not required, and using crankshaft and turning on/off the valves are not required.
