Abstract

A free piston generator based on a rigid synchronous transmission system is provided, which belongs to the technical field of power energy. The present disclosure solves the problems of low power generation efficiency and low stability of the existing free piston generator. The free piston generator based on the rigid synchronous transmission system includes a first linear generator set, a second linear generator set, a rigid synchronous transmission assembly, two high-pressure cylinders arranged at two ends of the first linear generator set, and two low-pressure cylinders arranged at two ends of the second linear generator set. The combustion product is firstly subjected to first-stage expansion in the high-pressure cylinder and is then subjected to second-stage expansion in the low-pressure cylinder, which effectively increases the energy utilization in exhaust gas, also increases the expansion work, and further improves the thermal efficiency and the power generation efficiency of the free piston generator. By means of the rigid synchronous transmission assembly, high-pressure pistons and low-pressure pistons are always kept in stable phase operation, so as to avoid the problems…
