Hybrid power device and system and power output construction method adopting fuel and liquid gas

Abstract

The invention discloses a hybrid power device adopting fuel and liquid gas. The hybrid power device comprises a four-stroke internal combustion engine cylinder and a pneumatic motor cylinder, wherein the pneumatic motor cylinder consists of a cylinder body, a piston and a cylinder cover, the piston is arranged in the cylinder body, the cylinder cover, the cylinder body and the piston are enclosed to define a gas source working cavity, and a gas inlet door, a gas outlet door and a spray nozzle extending into the gas source working cavity are arranged on the cylinder cover; the piston of the pneumatic motor cylinder and a piston of the internal combustion engine cylinder are connected with each other through a connecting rod mechanism, and slide alternatively in the corresponding cylinder bodies. The liquid gas and the fuel are adopted as basic sources for forming driving force, the gas emitted after the liquid gas does work can be effectively utilized as a pre-compressed gas source for further heat expansion, so that the efficiency can be furthest improved, and the pollution can be reduced. On the basis, the invention further provides a hybrid power system applying the power device and a hybrid power output construction method adopting fuel and liquid gas.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a hybrid power device, system and power output construction method using fuel and liquid gas. Background technique [0002] With the rapid development of human society, a large number of power machines have been widely used and have become an indispensable part of human society. As we all know, the existing ways of using power mechanical energy have brought serious damage to the natural environment, for example, the generation of environmental pollution such as heat energy emissions, greenhouse gas emissions, and soot particulate matter emissions, resulting in global warming, sea level rise, and climate change. Bad and other issues. [0003] Among them, the internal combustion engine with relatively mature technology is widely used in automobiles and various operating equipment, and the power output is realized by converting the chemical energy of the fuel into mechanical energy...

AI Technical Summary

Problems solved by technology

However, in the process of realizing this technology, high-pressure storage needs to consume 30% of the energy, and 30% of the energy is lost in the release and filling process, that is, the reuse rate of this method is only about 9%.

On this basis, the energy utilization rate of the internal combustion engine using this treatment method can only reach 20%-30%

[0005] In addition, the existing internal combustion engine consumes a lot of energy substances such as fossil fuels, and the emission of soot particles after fuel combustion directly pollutes the environment. Therefore, it is restricted by the relevant requirements for energy conservation and emission reduction.
