Abstract

The invention relates to a free-piston generator based on a split-cylinder thermodynamic cycle, which belongs to the technical field of power energy. The invention solves the problem of low power generation efficiency of the existing free piston generator. It includes a linear generator set and two sets of internal combustion units arranged at both ends of the linear generator set. The air is firstly compressed in the low-pressure cylinder group in the internal combustion set, and then compressed in the second stage in the high-pressure cylinder, which effectively improves the performance of the internal combustion engine. The intake pressure is beneficial to increase the average effective pressure in the working process, thereby improving the thermal efficiency and power generation efficiency of the free piston generator. The working fluid after combustion is expanded in the first stage in the high-pressure cylinder, and then expanded in the second stage in the low-pressure cylinder, which effectively improves the energy utilization rate in the exhaust gas, increases the expansion work, and further improves the efficiency of the free piston generator. thermal efficiency and power generation efficiency.

Description

technical field [0001] The invention relates to a free-piston generator based on a split-cylinder thermodynamic cycle, which belongs to the technical field of power energy. Background technique [0002] With the continuous development of society, people's demand for energy is increasing day by day, and the energy problem has become the main problem restricting the further development of all walks of life. Among various forms of energy, electric energy is one of the most widely used energy sources, and electric energy is mainly provided by diesel engines in industries such as vehicles and ships. In the traditional diesel engine power generation process, the form of energy transmission is firstly converted from the chemical energy of the fuel through the combustion of the diesel engine into the mechanical energy output by the crankshaft, and then this part of the mechanical energy drives the motor to generate electricity and converts it into electrical energy. The entire ener...
