Hybrid power device and system with fuel and direct-injection liquid gas and power output construction method

Abstract

The invention discloses a hybrid power device with fuel and direct-injection liquid gas. The hybrid power device comprises a four-stroke internal combustion engine cylinder and a pneumatic machine cylinder, wherein the pneumatic machine cylinder comprises a cylinder body, a piston arranged in the cylinder body and a cylinder cover, the cylinder body, the piston and the cylinder cover define a gas source work cavity, and the cylinder cover is provided with a gas inlet door, an exhaust door and a liquid injecting nozzle stretching into the gas source work cavity; the piston of the pneumatic machine cylinder is connected with a piston of the internal combustion engine cylinder through a link mechanism, so that the pistons can slide in corresponding cylinders in an alternating mode. The liquid gas and the fuel are used as a basic source for forming driving force, gas exhausted after the liquid gas acts is effectively utilized to be used as a pre-compression gas source which expands after being heated, and therefore efficiency can be improved to the largest extent, and pollution is lowered. The invention further provides a hybrid power system comprising the hybrid power device, and an output construction method of hybrid power with fuel and direct-injection liquid gas.

Description

technical field [0001] The invention relates to the field of engine technology, in particular to a hybrid power device, system and power output construction method using fuel and direct injection 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 ...
