Embodiment: the invention will be further described below in conjunction with accompanying drawing, but protection scope of the present invention is not limited to accompanying drawing and embodiment.
As shown in Figure 1, cylinder cap 3, cylinder platform 7, cylinder body 28 common formation cylinders, piston 27 is arranged in the cylinder body, and the cavity that the upper surface of cylinder platform and the internal surface of cylinder cap form is a gas storage chamber 2, and the upper end of the lower surface of cylinder platform and piston upper-end surface and the cylinder body partly cavity of inner side surface formation is firing chamber 10; Suction valve 4 and outlet valve 11 inlet and outlet of control cylinder are respectively arranged on the cylinder cap; Regulating the qi flowing in the channels pipeline 6 and jet pipe 26 are arranged in the cylinder platform, and there is Air-regulating valves 5 regulating the qi flowing in the channels pipeline upper end.The jet pipe two ends have little spout 12 and little spray valve 13 respectively; Big spout 9 and big spray valve 8.The unified regulation and control of timing case 1 suction valve, outlet valve, little spray valve, spray the keying campaign of valve and Air-regulating valves greatly.Wait to expect that chamber 25 is positioned at jet pipe top.Feeding tube 22 front ends enter chamber to be expected by cylinder platform side.Feeding stopper rod 21 1 ends are inserted in the feeding tube, and the other end is hinged with an end of locking connecting rod 17 by hinge eyes 20.The other end of stroke wheel 16 and locking connecting rod is hinged.Feeding tube and binder pipe 19 are connected at binder mouth 23 places.The binder pipe communicates with material-storing box 14 bottom opening places.Worm screw 18 is housed in the binder pipe, and the worm screw rear end is joining gear on worm 15.Preheater 24 is contained in outside the feeding tube.
During this internal combustion engine, the dust fuel in the material-storing box pushes worm screw and is pushed down in the feeding tube, after the heating of preheater high temperature reaches burning-point, is waited to expect in the chamber by the propelling of feeding stopper rod again.This moment, big or small spout was closed by size spray valve, waited to expect that indoor air is thin, and the dust fuel that reaches burning-point can not burn.Meanwhile suction valve and Air-regulating valves are opened, descent of piston, and fresh air sucks in the cylinder from suction port, and this process is a suction stroke, as shown in Figure 2.Piston arrives transfers to up under the flywheel effect of inertia and the compression fresh air after bottom dead center, and this moment, suction valve cut out, and Air-regulating valves is still being opened.Fresh air is compressed in gas storage chamber and the firing chamber during piston arrives top dead center, and gas pressure intensity reaches maximum value, and this process is a compression stroke, as shown in Figure 3.Transfer to descending at flywheel effect of inertia lower piston, Air-regulating valves is closed, descent of piston is during to ignition location, because combustion chamber volume increases, its air pressure inside is significantly less than the air pressure in the gas storage chamber, therefore when size spray valve is opened simultaneously, under the effect of pressure reduction, fresh air in the gas storage chamber just can form the too small spout of high speed rotating air communication and go out big spout through chamber to be expected, under the impact of this strand high speed rotating air-flow, wait to expect that the high-temperature dust burning in the chamber is dispelled, and fully mix, satisfied three conditions of dust explosion this moment with fresh air with the motion of air-flow, dust fuel just can acutely burn in the firing chamber, the outburst huge energy promotes the descent of piston acting, and this process is an explosion stroke, as shown in Figure 4.Must explanation be: this moment, on the linear position, the locking connecting rod was in blocking because feeding stopper rod, hinge eyes, locking connecting rod, stroke wheel axle center coexist, though the feeding stopper rod has been subjected to waiting to expect the effect of huge air pressure in the chamber, but still can't after move.Piston does work after bottom dead center, transfer to uply under wheel action, this moment size spray valve cuts out and outlet valve, Air-regulating valves are opened, and waste gas is discharged through relief opening under the compressing of piston, row was unblanked after meanwhile the stroke wheel was handled the locking connecting rod, the feeding stopper rod is moved backward, and the binder mouth is opened, and dust fuel pushes worm screw and is pushed down in the feeding tube, and be preheated and heat, for next work cycle is prepared, this process is an exhaust stroke, as shown in Figure 5.So far this internal-combustion engine has been finished a work cycle through four stroke operations.Watt level is to realize by the size of adjusting worm screw rotating speed and inlet open during this engine operation: the worm screw rotating speed is fast, and the dust fuel that enters the firing chamber is many; Inlet open is big, and the fresh air that enters the firing chamber is many, and the energy of burning outburst is big, and the power of motor is just high, otherwise then low.The structure of this internal-combustion engine only needs to change slightly, transforms the inlet and outlet mouth into be placed in the cylinder body middle part port and baffle plate, just is applicable to two-stroke reciprocating combustion engine.
The invention provides a kind of dependence powder blast principle, use the novel reciprocating internal combustion engine of dust fuel work by combustion.Found to substitute the day by day exhausted disposable fuel such as the renewable New-type fuel of oil, natural gas etc., the use of this internal combustion engine and dust fuel will be opened up new way for energy regeneration, continuous utilization.
