Abstract

The invention relates to a pressure lubrication system of a multi-module free piston internal combustion engine generator and belongs to the field of energy power. Engine oil in an engine oil tank is pumped by an engine oil pump, is filtered by an engine oil filter, is subsequently divided into two branches and enters first oil inlet holes of gas scavenging boxes on two sides; lubrication oil flowing into the first oil inlet holes is conveyed into each oil dividing passages through oil lines in the gas scavenging boxes, reaches lubrication oil cavities in the gas scavenging boxes, and gaps between the lubrication cavities and connection rod active cells through oil dividing passages, and then enters an oil passage in a piston connection rod component and flows into a piston-cylinder sleeve friction pair through an oil outlet of the oil passage so as to continuously lubricate the friction surface. The system is reliable to operate and strong in adaptability; the engine oil pump is electric and is capable of conveniently carrying out accurate electronic control according to different operation conditions of the engine; the lubrication oil cavities and the lubrication passages are distributed in a free piston generator module; the pressure lubrication system of the multi-module free piston internal combustion engine generator is compact in structure and can save space and achieve high volume 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 ...
