Abstract

The invention relates to a pressure lubrication system of a free-piston internal combustion generator, 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 lubricating oil cavity and the lubricating oil cavity through the first oil inlet hole and the oil delivery channel of the scavenging air box on both sides. The gap between the connecting rod mover and the connecting rod mover; then enters the oil passage in the piston connecting rod assembly; then flows into the piston-cylinder liner friction pair through the oil outlet of the oil passage to realize continuous lubrication of this friction surface; the system adopts The form of pressure lubrication has no coupling relationship with the movement process of the free piston generator, and the work is reliable and adaptable; the oil pump adopts electric type, which is convenient for precise electronic control according to different working conditions of the engine; the arrangement of lubricating oil chamber and lubricating oil passage Inside the free-piston generator module, the structure is compact and space-saving, and it is easy to achieve high volumetric power.

Description

technical field [0001] The invention relates to a pressure lubrication system of a free-piston internal combustion generator, 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 the powe...
