Abstract

The invention relates to a multi-module free-piston internal combustion generator pressure lubrication system, which belongs to the field of energy and power. The oil in the oil tank is pumped out by the oil pump, and after being filtered by the oil filter, it is divided into two branches, and enters the first oil inlet hole of the scavenging air box on both sides, and the lubricating oil flowing into the first oil inlet hole passes through the The oil circuit in the scavenging air box is sent to each oil distribution passage, and then reaches the lubricating oil chamber inside each scavenging air box, the gap between the lubricating oil chamber and the connecting rod mover; and then enters the piston connecting rod assembly into the oil passage; then through the oil outlet of the oil passage, it flows into the piston-cylinder liner friction pair to achieve continuous lubrication of this friction surface; the system is reliable and adaptable; the oil pump is electric, which is convenient Precise electronic control of the situation; the lubricating oil chamber and lubricating oil passage are arranged inside the free piston generator module, which has a compact structure, saves space, and is easy to achieve high volumetric power.

Description

technical field [0001] The invention relates to a multi-module free-piston internal combustion generator pressure lubrication system, which belongs to the field of energy and power. Background technique [0002] The free-piston internal combustion generator is a new type of energy conversion device formed after the coupling of the free-piston internal combustion engine and the linear generator. The combustion chambers on both sides sequentially push the piston connecting rod to reciprocate and linearly move to cut the magnetic induction line of the middle motor to generate electricity. The structure does not have a crank-link mechanism, and has the advantages of simple structure, high power density and low emission. [0003] In a free-piston internal combustion generator, the friction surface between the piston ring and the cylinder liner moves relative to each other at high speed, forming the only source of friction loss in the entire power system, which not only increases ...
