Problems solved by technology

[0002] It has a history of 200 years to use the vaporizer to heat and vaporize the working fluid, criticalize it, supercriticalize it, ultra-supercriticalize it, or overheat it as a system to drive the power mechanism to do work, and it is still in use today. The requirements of the mechanism are very high, which not only affects the cost of the system, but also affects the efficiency of the system. Therefore, it is necessary to invent a new type of engine with phase cycle as the source power.

Embodiment 1

[0029] Such as figure 1 The shown split timing phase cycle engine includes a cylinder-piston mechanism 1 and a carburetor 2, the liquid phase region of the carburetor 2 communicates with the cylinder of the cylinder-piston mechanism 1, and the liquid phase region of the carburetor 2 passes through a cooler 7 communicates with the liquid inlet of the speed-type pumping device 3, the liquid outlet of the speed-type pumping device 3 is provided with a control valve 4, and the control valve 4 communicates with the gas phase area of ​​the vaporizer 2, and the control valve 4 is controlled by The pulsation control device 5 controls, and the carburetor 2 described in the figure is set as an external combustion carburetor.

[0030] During specific implementation, the speed type pumping device 3 can be selectively set as a centrifugal pumping device, a vortex pumping device, a mixed flow pumping device, an axial flow pumping device or be set as a speed type pumping device such as a je...

Embodiment 2

[0032] Such as figure 2 The shown split timing phase cycle engine includes a cylinder-piston mechanism 1 and a carburetor 2, the liquid phase region of the carburetor 2 communicates with the cylinder of the cylinder-piston mechanism 1, and the liquid phase region of the carburetor 2 passes through a cooler 7 communicates with the liquid inlet of the volumetric pumping device 8, and the liquid outlet of the volumetric pumping device 8 communicates with the accumulator 6, and the accumulator 6 communicates with the gas phase region of the vaporizer 2. A pulsation control device 5 is provided on the communication channel between the accumulator 6 and the gas phase region of the carburetor 2, the carburetor 1 in the figure is set as an external combustion carburetor, and the accumulator 6 in the figure is set as a spring type energy storage The volumetric pumping device 8 described in the figure is set as a Roots pumping device.

[0033] As a changeable embodiment, the accumulat...

Embodiment 3

[0036] Such as image 3 The shown split timing phase cycle engine is based on Embodiment 1: a nozzle 9 is set on the gas phase region of the carburetor 2, and the control valve 4 is connected to the gas phase of the carburetor 1 through the nozzle 9. area connected.

[0037] As an alternative embodiment, the nozzle 9 is not connected to the control valve 4, but the nozzle 9 is connected to other devices capable of providing cooling liquid instead.

Abstract

The invention discloses a split timing phase-cycle engine comprising a cylinder piston mechanism and a carburetor. A liquid phase zone of the carburetor is communicated with a cylinder of the cylinder piston mechanism. A liquid phase zone cooler of the carburetor is communicated with a liquid inlet of a speed pumping device. A liquid outlet of the speed pumping device is provided with a control valve which is communicated with a gas phase zone of the carburetor. The control valve is controlled by a pulse control device. The split timing phase-cycle engine is simple in structure, high in efficiency and low in cost.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a split timing phase cycle engine. Background technique [0002] It has a history of 200 years to use the vaporizer to heat and vaporize the working fluid, criticalize it, supercriticalize it, ultra-supercriticalize it, or overheat it as a system to drive the power mechanism to do work, and it is still in use today. The requirements of the mechanism are very high, which not only affects the cost of the system, but also affects the efficiency of the system. Therefore, it is necessary to invent a new type of engine with phase cycle as the source power. Contents of the invention [0003] In order to solve the above problems, the technical scheme proposed by the present invention is as follows: [0004] Option 1: A split timing phase cycle engine, including a cylinder-piston mechanism and a carburetor, the liquid-phase region of the carburetor communicates with the cylinder...
