Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the utility model embodiment 2 structural representation.
In figure: igniting and oil spout are 1, inlet and outlet door 2, cylinder body 3, piston 4, piston push rod connector 5, mover 6, stator 7, Engine Push Rod positioning plate 8, upper positioning guide plate 9, push rod be every bar magnet 10, lower positioning guide plate 11, spring lever 12, generator fixing bottom-plate 13.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further.
Embodiment 1 is as shown in Fig. 1.Embodiment 1 comprises two permanent magnet linear generators that contain mover 6, stator 7, contain two single cylinders 3, piston 4, igniting and oil spouts and be 1, the internal-combustion engine of inlet and exhaust valve 2, comprise that bearing by straight-bar, the setting of straight-bar middle-end is, the spring lever 12 that the push rod that straight-bar two ends arrange forms.Igniting and oil spout are 1 to be arranged on the crown center of cylinder 3, enter, apex igniting and oil spout that exhaust valve 2 is arranged on cylinder are 1 both sides, cylinder 3 is connected with stator 7, piston push rod connector 5 docks with the main shaft of mover 6, mover 6 is fixed in linear motor stator electric 7 with lower positioning guide plate 11 by upper positioning guide plate 9, Engine Push Rod positioning plate 8 is fixed on cylinder 3 cylinder bodies, upper positioning guide plate 9 is arranged on the upper end of stator 7, push rod is arranged on the lower shaft on mover 6 every bar magnet 10, lower positioning guide plate 11 is arranged on stator 7 lower ends, stator 7 is fixed on generator fixing bottom-plate 13, piston 4 is on cylinder 3 is interior, lower motion.Two permanent magnet linear generators be adjacent, be symmetrical arranged side by side, bearing is fixed on generator fixing bottom-plate 13, the push rod at two ends matches with two movers 6 respectively.Two single cylinder free piston internal combustion engines and two linear permanent-magnet generators dock separately side by side, by the bottom lever drive generator that forms a whole that freely bounces.Left and right combustion gas are outburst alternately, piston assembly (comprise left and right piston and both connecting rod of being rigidly connected, connecting rod is double does the secondary of linear electric generator) is moved up and down, thereby realize the magnetic force line cutting of linear electric generator, produce electric energy, and exported by linear induction motor system.
, there is not connecting rod and distribution device in feature of the present utility model: 1, mechanism is simple, piston is unique movement parts, and whole motor can have more compact structure and have higher specific power.Meanwhile, the minimizing of movement parts has also improved the reliability of system and the loss of energy; 2, owing to adopting the lever that freely bounces, make engine piston vertical motion up and down, overcome the weakness of opposed motion, increased the time of a stroke acting simultaneously, and extended linear electric motor cutting magnetic line length, the broken-proof of permanent magnet is played to direct effect; 3, frictional loss trifle energy emission reduction efficiency is high, and a large amount of friction energy loss that Liao Gai mechanism brings are fundamentally eliminated in the cancellation of connecting rod; Motor be just subject to by the quality that moves up and down, gas pressure,
Piston ring pressure is exerted oneself and frictional force on producing, so this generator has potential more high thermal efficiency; Owing to not rotatablely moving and bearing, the frictional loss of engine is very little, can realize running dry in the future, and energy-saving and emission-reduction efficiency is high; 4, good can balance, adopt the twin-tub piston structure that moves up and down side by side, this generator system natural equilibrium.The continuation that has solved energy owing to freely bouncing is extended, and energy obtains conservation, whole system overall process is moved up and down freely, stable equilibrium; 5, variable compression ratio, incendivity pluralities of fuel, piston is not subject to the constraint of mechanical coupling, and therefore the upper and lower stroke of adjustable this generator, realizes alterable compression ratio, thereby applicable to the combustion requirements of pluralities of fuel.The advantage that variable compression ratio is more outstanding is to make this generator be suitable for adopting pluralities of fuel.But for conventional crank-axle engine, change compression ratio and mean increasing engine structure complexity, need weigh the advantages and disadvantages cautiously: and for this generator, without any structural change, so multifuel firing is applied and had innate advantage in this generator; 6, can walk abreast by many these generators, the selection of power and the Installation Flexibility of unit are large.Can combine with many, increase generator total output.During this machine generator failure of separate unit, do not affect the continuous operation of whole unit.Except above-mentioned feature, the utility model also has following potential advantage: linear electric motor when starting as the starter motor of engine, when engine parking as break, when engine steady running as generator, also as the do-part of control system; Under certain determines operating mode, move, can realize high efficiency and low emission by strategy; Above performance characteristics based on this invention, it has good Economy, emission performance, many fuel tolerances, makes in the lump day by day to become in energy problem, environmental problem today of focus, and this invention is had place to show one's prowess; Structure is extremely compact, efficient, low emission, can increase output power by adjusting size, is very applied as the power plant of electric vehicle.The high power density possessing, adapt to many fuel characteristics, the difficulty that also will be conducive to improve the vital capacity of military vehicle (electric armored vehicle, unmanned aerial vehicle catapult car, electric tank) and reduce logistics support.
Embodiment 2 is as shown in Fig. 2.What embodiment 2 was different from embodiment 1 is that permanent magnet linear generator becomes 2 pairs of settings, has four permanent magnet linear generators, and every two form 1 pair.Every pair of permanent magnet linear generator is identical with embodiment 1, forms two groups, and power is larger.The utility model also can adopt 3 pairs and 3 pairs of above combining forms.
The utility model thermal efficiency ratio traditional combustion engine improves 20%, is combined with permanent magnet linear generator, and generator power is because greatly improving, and generator efficiency is greater than 97%.It can be used pluralities of fuel maximum bright spot, comprises hydrogen.
