Embodiment Construction

[0013] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] like figure 1 As shown, the present invention includes: a first piston 1, a second piston 2, a connecting rod 3, a first combustion chamber 4, a second combustion chamber 5, a first fuel nozzle 6, a second fuel nozzle 7, a first air inlet 8. Second air inlet 9, first air outlet 10, second air outlet 11, permanent magnet 12, coil 13, iron core 14, piston position sensor 15, electronic control unit 16, first high-pressure starting pump 17 , the second high-pressure starting pump 18, the first turbocharger 19, the second turbocharger 20, and the cylinder 21.

[0015] The first piston 1 and the second piston 2 form an opposing whole through the connecting rod 3 in the middle, and the connecting rod 3 is arranged with a permanent magnet 12, which reciprocates left and right in the cylinder 21 together with the opposing structure. The ...

Abstract

The present invention relates to a free piston type internal combustion engine power generation system, belonging to the field of internal combustion engine technology. Said invention includes left and right two pistons, connecting rod, cylinder, left and right oppositely-arranged two combustion chambers, fuel oil nozzle, air inlet, air outlet, permanent magnet placed on the connecting rod, coil outside of cylinder, iron core, piston position sensor, electronic control unit, two external high-pressure starting pumps and turbo supercharger. The power generation system is set between two combustion chambers. Besides, said invention also provides the concrete connection mode of all the above-mentioned portions and the working principle of said power generation system.

Description

technical field [0001] The invention relates to an internal combustion engine power generation system, in particular to a free-piston internal combustion engine power generation system, which belongs to the technical field of internal combustion engines. Background technique [0002] The free-piston internal combustion engine means that the engine cancels the crank-and-rod mechanism of the usual internal combustion engine. The law of piston movement is controlled by the combustion law in the combustion chambers at both ends, and changes with the working conditions of the engine. Because it is not bound by mechanical rods, its power piston is free, that is, the compression ratio is variable. Compared with the traditional crankshaft engine, the crankshaft connecting rod mechanism that converts the reciprocating motion of the piston into rotational motion in the crankshaft internal combustion engine is omitted, and it has the advantages of simple structure, small number of part...
