Abstract

The invention discloses a reverse recoil brake design method, belongs to the field of design of guns, and can solve the recoil problem of the guns. The reverse recoil brake design method is characterized by using an automatic shutter mounted in a shutter box for automatically controlling a moving direction of high-pressure air, so that the high-pressure air is exhausted from transverse outlet cylinders at two sides of a joint cylinder to convert the non-control distribution of pressure of the guns to the control distribution. The reverse recoil brake design method has main purposes of thoroughly eliminating the recoil force of the guns and quickly stopping the recoil motion of the guns.

Description

Inverse recoil muzzle brake design method

(1) technical field

Firearms design.

(2) background technology

The function of firearms muzzle brake is the recoil motion reducing firearms, and its highest standard thoroughly eliminates recoil motion.Because existing muzzle brake performance is too poor, many important military equipments are all abandoned using < such as tank >, the rocket gun of breech mouth flame can only use the rocket projectile that initial velocity is very low, cost is very high, and precision is very poor, fixing Area Objects can only be hit, use value is not had to the point target of movement.

Existing most of muzzle brake is not owing to having automatic gate, cannot the pressure distribution of ACTIVE CONTROL firearms, the horizontal exit design of muzzle brake side obtains and much also gets half the result with twice the effort very greatly, because the air-flow of most of HTHP just has little time to expand, thorax mouth is in the past discharged, must form powerful recoil, this is the exercising result of the law of inertia.I research and development without seat power muzzle brake < application number: 201410313394.6> is provided with automatic gate, possesses stronger active control ability, but the automatic gate of this muzzle brake needs the back outlet of beating piston fast under high-temperature and high-pressure conditions and its structure there is no reinforcement design, multiple and the system of easy distortion causing trouble moves back limited in one's ability and maintenance not easily, and therefore this product only can be used for slow fire firearms and use cost is higher.

The conventional firearms precision of high gun pressure is very high, and cost is very low, has good strike effect to fixed target, moving target, point target, Area Objects, and its shortcoming is that recoil is very large.This shortcoming is exactly the technical barrier that the present invention needs to solve.

(3) summary of the invention

The technical scheme of inverse recoil muzzle brake is the direction of motion using the automatic gate be arranged in shutter box automatically to control powder gas, and having changed into without control distribution of gaseous-pressure is controlled distribution.Its direct result of use is the recoil significantly reducing firearms, thus improves the fire accuracy of rapid fire firearms, the Firing Velocity improving slow fire firearms, minimizing firearms own wt, the service life increasing firearms and the scope of application; It indirectly result of use be reduce labour intensity and the environmental pollution (because powder gas is pernicious gas) of ammunition consumption and user.

Example 1: after the recoil of firearms significantly reduces, its vibrations when shooting are reduced to negligible degree; Wherein the burst-firing precision of firearms will significantly improve automatically, and the consumption of ammunition can be minimized, and the service life of firearms will extend naturally, and the labour intensity of user will reduce naturally; Wherein semi-automatic firearms and the pointing time of non-automatic firearms after shooting will obviously shorten, and the Firing Velocity of firearms will significantly improve.

Example 2: after installing inverse recoil muzzle brake additional, because barrel amount of squat is very little, do not need to configure in advance, be conducive to barrel natural equilibrium, shorten full gun commander's degree and reduce live wire height, save the hydraulic pressure recoil absorber that fault rate is higher, balancing machine also can design very exquisite, as long as the structural strength of gun carriage can bear the vibrational energy of cannon in motion process, therefore also can design very exquisite, these advantages are combined and the weight of cannon are significantly reduced, fault rate significantly reduces, therefore the scope of application of cannon just can be expanded, user just can be provided to large caliber gun on speedboat and light vehicle.

Example 3: existing tank can only be equipped with 125mm cannon at most, own wt but reaches about 60 tons and (resists recoil with self gravitation, otherwise will big gun ring car turn over), although engine power is up to 1000 horsepowers, maximum speed only has about 60 kilometers/hour, the scope of application is also subject to strict restriction (can not float river of crossing a river, the bridge that heavy burden ability is less and road can not pass through).After being equipped with inverse recoil muzzle brake, own wt can be equipped with 152mm or 155mm large caliber gun at the alligator tank of about 20 tons, utilize large caliber gun effective range large, fire accuracy is high, injure the advantage that energy is large, our tank just can stop and carry out precision strike unhurriedly (this is because the quiet of tank gun exceeds 10 percentage point than dynamic to dynamic shooting average to dynamic shooting average outside the effective range of hostile tanks cannon, quiet to quiet shooting than the dynamic hit rate dynamic shooting being exceeded to 20 percentage points, the problem of light tank protective capacities deficiency is made up thus simultaneously), if be equipped with the engine of more than 1000 horsepowers, just can enter fast or withdraw from battlefield, enemy is made to lose belligerent initiative.Less own wt not only makes vehicle obtain very high maximal rate, also makes vehicle float river of crossing a river, the road less by heavy burden ability and bridge etc.The production cost that relatively existing tank is less and use cost make the military can equip more new type tank by same financial resources.

In fig. 8: 11 are upper cylinder sleeves, 12 are positioning screw caps, 15 are connecting rods, 16 are pistons, 17 is cored screws, 18 is below otch of upper cylinder sleeve.Cylinder head is held a concurrent post by cored screw, its front end is sealing, rear end is interior hexagon, stage casing is one section of hollow pipe, with being screwed between it and upper cylinder sleeve, in order to improve air-tightness and avoid maloperation, therebetween gap will be designed empty-handedly cannot operate, during normal use, hollow screw front end should cover the half or a greater part of of the below otch of upper cylinder, in order to allow reader's accurate understanding, the front end of figure hollow core screw rod is drawn in the rear end of the below otch of cylinder sleeve, and the rear end of piston is in the front end of the below otch of upper cylinder sleeve.The structure of piston and connecting rod with assemble to be equipped with the structure of piston in general internal combustion engine and connecting rod and the outer surface assembling identical < piston rear end three road oil rings, together with compression ring, the both sides of piston nose are provided with two mutual through pin holes, jump-ring slot is had in hole, the pin hole of rod rear end is overlapped with two pin holes of piston nose and inserts pin, then jump ring is put into the jump-ring slot of piston, can piston, linkage assemblies be done as a whole from the inner > of cylinder sleeve the threading of front end.

In fig .9: 8 are positioning sleeves, 10 are screws, 11 are upper cylinder sleeves, 12 are positioning screw caps, 13 are lower cylinder sleeves, 14 be gun barrel or gun tube, 15 are connecting rods, 17 is cored screws.Weld after the below otch of upper cylinder sleeve overlaps completely with the top otch of lower cylinder sleeve and formalize, the two forms threeway cylinder sleeve jointly, takes off cored screw, and maintain cylinder with regard to available brush, maintenance work is very convenient.

In Fig. 10: 19 are door-plates, 20 is reinforcements.

In fig. 11: 19 are door-plates, 20 are reinforcements, 21 are inner sleeves, 22 is hooks.All setting is welded above between each parts, reinforcement on small caliber piece shutter can be designed to " work " font, shutter on heavy caliber gun can not have reinforcement, because same material has higher structural strength when area is less, small-bore gun confrontation amount restriction requires very high, is not suitable for this product.

In fig. 12: 23 are screw rods, 24 are steel wire rope sockets, 25 are square pads, 26 is nuts.Steel wire rope socket is inserted in one end of steel wire rope, and then tightening nuts just can firmly be locked steel wire rope and can not injure steel wire rope, and being convenient to again install < is all a plane > up and down.

In fig. 13: 27 are cover plates, 28 are lower plates, 29 are side clamping plate, 30 is outer sleeves, and all weld setting between each parts, the gap between side clamping plate and outer sleeve must be welded flat; The rearview of shutter box is identical with this front view, and the external diameter of interface cylinder equals cover plate and lower plate, two pieces of side clamping plate form foursquare height and width, during assembling, this square is aimed in the front end of interface cylinder and welds.

In fig. 14: the outside otch, 33 of 19 are door-plates, 20 are reinforcements, 21 are inner sleeves, 27 are cover plates, 28 are lower plates, 29 are side clamping plate, 30 is outer sleeves, 31 to be inner incisions, 32 of outer sleeve be outer sleeve be link up with outside inner sleeve upper end, 34 are fast gate slotes, 35 are kickers.

For the ease of the understanding of reader, inside and outside two sleeves are moved to the right side of figure by author, the outer guillotine cutting mouth of outer sleeve is the tracks linked up with outside inner sleeve upper end, in order to anti-dust enters, after kicker loads outer sleeve together with inner sleeve, from the outside the outside otch of outer sleeve is covered with iron sheet, therefore no longer draw in figure afterwards; Fast gate slot is the tracks of shutter, and gap is therebetween wanted little and can be moved to shutter, and too senior general produces collision and noise; The inner incision of outer sleeve will overlap with fast gate slot and become a part for fast gate slot, and outer sleeve is the tracks of inner sleeve and kicker, and the upper end of inner sleeve is opening, and lower end is welded with the base plate of level, and there are a steel wire rope socket in the central authorities of its base plate; The lower end of outer sleeve can extend to the lower end of inner sleeve if desired.Kicker is arranged in inner sleeve, and its length equals the overall length of whole sleeve <21 and 30> inner chamber; When the front surface of shutter has a reinforcement, the width (see 37 of Figure 15) identical with reinforcement will be given prominence to forward in the stage casing of the front plate of lower plate, avoid toll bar accident occurs, if desired can the outside nick translation of outer sleeve to the dead ahead of outer sleeve and dead astern (increasing an otch), corresponding therewith, link up with outside inner sleeve upper end and also will increase by one symmetrically, this method can strengthen the area of inner sleeve upper surface, improve crashproof ability, extend the service life of product.

In fig .15: 24 are steel wire rope sockets, 27 are cover plates, 29 are side clamping plate, 30 are outer sleeves, 36 is shallow slots (2-3mm), 37 is protuberances of shutter lower plate when having a reinforcement.The function of shallow slot is anticollision, because shutter is identical with the height of inner sleeve, if shutter is slightly short, sealing effectiveness is bad, when shutter to go upward to the lower surface of cover plate with inner sleeve, < is shown in Figure 11 and Figure 18 >, the two all can clash into the lower surface of cover plate, the upper surface that shutter is sharp will inevitably be damaged < and see Figure 10 >, and the function of shutter is fast shut-off high pressure draught, being designed to the sharp edge of a knife and can reducing the resistance of motion of its upper surface, the emission rate improving the reaction speed < firearms of shutter is the > calculated with millisecond, other each parts are all in the below of cover plate, so represented by dashed line.

In figure 16: 38 are gears, 39 are gear shafts, 40 are slotted disks, 41 are axle sleeves, 42 are sleeve racks, 43 are steel wire rope set screws, 44 is pin mouths.There are a socket supporting with gear shaft and the pin mouth the same with pin mouth in the central authorities of slotted disk, one end < slotted disk being enclosed within axle is shown in Figure 17 > and makes the salty conjunction of the pin of the two, then squeezes into one end that slotted disk can be fixed on axle by pin; One end of steel wire rope is locked in after steel wire rope set screw < is shown in Figure 12 > inside, again in the groove of cable drilling slotted disk, then inside steel wire rope set screw being welded on slotted disk makes it to become in the therefore later figure of a part of < of slotted disk no longer draws its >, therefore should cut out in the relevant position of slotted disk in advance one than steel wire rope set screw bigger and hole that is that communicate with the groove of slotted disk.In order to the internal state allowing reader see gear shaft assembly clearly, author takes slotted disk face to face away.

In fig. 17: 38 are gears, 39 are gear shafts, 40 are slotted disks, 41 are axle sleeves, 42 is sleeve racks.An axle of gear shaft to be exactly stage casing a be gear, the internal diameter of axle sleeve is slightly larger than the diameter of gear shaft, and axle can be rotated, and the mid point above it will bore an oil hole; The function of axle sleeve is the motion in limiting gear axle all around upper and lower any direction, the upper end of sleeve rack is welded on the mid point of axle sleeve lower surface, and its lower end welding is exactly that this figure > is fixed on finished product upper surface whole gear shaft assembly <.

In figure 18: 27 is cover plates, 28 is lower plates, 29 is side clamping plate, 30 is outer sleeves, 6 is Exported Cones, 21 is lower sleeves, 45 is steel wire ropes, 38 is gears, 19 is door-plates, 20 is reinforcements, 2 is 2> that interface board < is shown in Fig. 1, 1 is the 1> that interface cylinder < is shown in Fig. 1, 3 is 3> that stiffener < is shown in Fig. 1, 48 is fixing brake hoops, 15 is connecting rods, 43 is steel wire rope set screws, 46 is top covers.

In order to the situation allowing reader see top cover inside clearly, top cover is represented by dashed line, steel wire rope inserts cover plate steel wire rope socket < after drawing from the steel wire rope set screw slotted disk is shown in Figure 15 >, the central authorities of Figure 14 > are seen again through kicker <, again through the steel wire rope socket of inner sleeve lower end, finally its lower end is locked in the inside of the steel wire rope set screw being close to inner sleeve lower surface, the girth of slotted disk will equal the stroke < of inner sleeve and shutter <19 and 20> because the two contour >, the distance namely between lower plate and cover plate, when bullet passes through after above shutter, piston < is shown in Fig. 8 and illustrates that > promotes connecting rod <15> and travels forward under the effect of cylinder inner high voltage gas, connecting rod is by the tooth transmitting gear <38 by its front end upper surface, the tooth of the two is wanted to support the use >, thus rotate slotted disk and be fixed on steel wire rope in slotted disk by upper end and drive the shutter assembly being fixed on steel wire rope lower end to go upward to hook outside the lower surface < inner sleeve of cover plate and inner sleeve upper end to collide the lower surface > of cover plate, compress kicker simultaneously, now gear and slotted disk are by just rotating one week, movable brake hoop < is shown in that the 47> of Figure 19 and Figure 20 just strikes the fixing brake hoop <48 in front, the stroke of movable brake hoop will equal gear girth > as can be seen here, make the dump energy of piston and link assembly can not damage the tooth of gear and connecting rod, when the gas pressure in cylinder is less than the elastic force of kicker, kicker drives all movable parts to return initial point, now hook the lower surface of otch outside outer sleeve outside inner sleeve upper end, make the dump energy of shutter assembly can not damage the tooth of gear and connecting rod, now movable brake hoop clashes into the fixing brake hoop at rear, make the dump energy of piston and link assembly can not damage the tooth of gear and connecting rod.

Should emphasize: shutter should be put in place by fast uplink rear above it at bullet, gases at high pressure is discharged from the horizontal Exported Cone of both sides, too early will block bullet, will have a large amount of gases at high pressure too late and discharge at a high speed, and form larger recoil; Therefore the movement velocity < of control piston and link assembly i.e. the intake velocity > of control cylinder is most important, method is exactly the size controlling the interface of upper cylinder sleeve and lower cylinder sleeve by rotating cored screw, controls the speed that gases at high pressure enter cylinder from gun barrel or gun tube; Under normal behaviour in service, the front end of cored screw should cover the half or a greater part of of the interface area of cylinder sleeve and lower cylinder sleeve, if it is not enough that interface all decontrols still air inlet, shutter is caused to react too slow, the diameter of cylinder sleeve and lower cylinder sleeve should be strengthened, the intake velocity of intensifying cylinder, the diameter of each parts supporting with it also will correspondingly strengthen, also the length of big connecting rod can be added, whole cylinder assembly is moved suitable distance backward, the inlet period of cylinder is lengthened, also can two measures carry out simultaneously.

Operation principle: gunpowder after bore blast, promote simultaneously bullet forward, barrel moves backward because the quality of bullet is very little comparatively speaking, the quality of barrel is very large, so bullet obtains a very large acceleration, barrel obtains a very little acceleration; But powder gas is different to the acceleration time of the two, bullet leaves bore just to be stopped accelerating later, only rely on the inertia force flight forward of self, and the accelerator of barrel is present in whole gunpowder explosion process, until the gaseous-pressure in bore is zero just stopping, so existing cannon only has the long recoil of barrel could obtain less recoil energy.Existing tank gun generally adopts barrel short recoil radiation pattern by the restriction in gun turret space, must obtain very large recoil energy, have to strengthen complete vehicle quality, otherwise will turn over by big gun sound car.Install the part that the later muzzle brake of inverse recoil muzzle brake becomes barrel additional, bullet leaves the front channel of the cutoff high air-flow at once of automatic gate after bore, high pressure draught will be transferred to the thrust of bullet with it automatic gate, promote automatic gate, whole muzzle brake and whole barrel to travel forward, according to the pressure identifiability principle of explosive charge, recoil equal and opposite in direction, the direction of this thrust and barrel are contrary, so the two is cancelled out each other; Barrel only relies on self inertia force to do recoil motion.As can be seen here: one be inverse recoil muzzle brake can significantly reduce recoil to the action time < of barrel and thrust the equal > of the acceleration time to bullet, supporting cannon adopts barrel short recoil mode to launch also can obtain very little recoil energy; Two is that the maximum system that barrel needs is moved back power (namely maximum recoil resistance) and equaled barrel inertia force.

In Figure 19: 17 are cored screws, 12 are positioning screw caps, 13 are lower cylinder sleeves, 30 are outer sleeves, 21 are inner sleeves, 6 are Exported Cones, 45 are steel wire ropes, 43 are steel wire rope set screws, 3 are stiffeners, 10 are screws, 1 be interface cylinder, 2 are interface boards, 14 be gun barrel or gun tube, 47 are movable brake hoops, 48 are fixing brake hoops, 11 are upper cylinder sleeves, 46 are top covers, 39 are gear shafts, 15 are connecting rods, 7 are lower margin limits, 8 are positioning sleeves, 27 are cover plates, 42 is sleeve racks.

The usage of positioning screw cap is shown in Fig. 7 and explanation thereof, the structure of positioning sleeve and usage are shown in Fig. 6 and explanation thereof, the structure of steel wire rope set screw and usage are shown in Figure 12 and explanation thereof, fixing brake hoop is welded on the upper surface of stiffener, its internal diameter is slightly larger than the size (the connecting rod stage casing at movable brake hoop place is passed from the central authorities of fixing brake hoop) of connecting rod, its top center has an oil hole, it thereunder should be welded with the pad of a suitable thickness time highly not enough, the internal diameter of movable brake hoop equals the size of connecting rod, a hole is had above it, being burnt heat with fire makes it become large, then the relevant position of connecting rod is enclosed within, can locate after it is cold, then in hole from the upper side, itself and connecting rod are welded into an entirety (this hole will be welded flat), guarantee the reliability of product.

In fig. 20: 17 are cored screws, 12 are positioning screw caps, 11 are upper cylinder sleeves, 8 are positioning sleeves, 15 are connecting rods, 6 are Exported Cones, 7 are lower margin limits, 38 are gears, 45 are steel wire ropes, 27 are cover plates, 10 are screws, 1 be interface cylinder, 41 are axle sleeves, 48 are fixing brake hoops, 46 are top covers, 47 are movable brake hoops, 14 is gun barrel or gun tube.Interface cylinder thread connecting mode is arranged on the outer surface of gun barrel or gun tube front end, and the relevant position of parts cover plate corresponding to the lower margin limit of top cover and horizontal Exported Cone will get out the top cover set screw hole of some.

In figure 21: 6 are Exported Cones, 7 are lower margin limits, 1 be interface cylinder, 14 be gun barrel or gun tube, 49 are discharge directions, 50 are back rake angle X, 51 are F (side), 52 is F (front).3 screw rod sockets the same with common horizontal Exported Cone will be bored in the side on lower margin limit, just can complete positioning work with screw through the screw rod socket on the stiffener of this some holes and interface cylinder.

Common Exported cylinder only has the function of shunting, and the power Exported Cone of disappearing has shunting and the power two kinds of functions that disappear, because discharge directions is proceeds posterolateral to the common horizontal Exported Cone of < only discharged to both sides >, according to active force and reaction force principle, high pressure draught must be contrary to the power Exported Cone direction that disappears while discharging at a high speed, equal-sized thrust F (pushing away), this power can be analyzed to a thrust F to side (side) and thrust F (front) forwards, so F (front)=F (pushing away) sinx, suffered by two Exported Cones in left and right, forward thrust sum is F (front)=2F (pushing away) sinx, when back rake angle is 0, forward thrust is 0, when back rake angle is 90 °, thrust 100% is converted into forward thrust, recoil equal and opposite in direction suffered by this power and barrel, direction is contrary, so two power are cancelled out each other, barrel stops recoil at once, therefore the recoil of cannon is extremely short, can save the hydraulic pressure recoil absorber that fault rate is higher, the destructive power of cannon to shipping platform correspondingly reduces, therefore supporting cannon and haulage vehicle thereof or boats and ships can realize simplifying, lightness and low fault.If produce by 45 ° of back rake angles in this figure the power Exported Cone that disappears, the thrust of 70% is then only had to be converted into forward thrust < i.e. recoil resistance >, cannon will continue recoil, if the back rake angle of this figure is modified to 90 °, barrel stops recoil at once, but there is the larger too high > of potential safety hazard < drain pressure, therefore this figure mainly uses as the instrument of mechanical analysis.The maximum system power of moving back needed due to cannon equals barrel inertia force { that is: 2F (pushing away) equals barrel inertia force }, the system that cannon needs is moved back power (namely unnecessary barrel inertia force) and substitutes into the formula that this section write and just can obtain the back rake angle that the supporting power of disappearing goes out cylinder needs; I point out simultaneously, and during cannon automatic fire, the barrel inertia force of necessity can not be offset, unless this big gun adopts other automated manner or without the need to automatic fire.

In fig. 22: 1 be interface cylinder, 3 are stiffeners, 6 are Exported Cones, 7 are lower margin limits, 14 be gun barrel or gun tube, 49 is discharge directions.

In fig 23: 3 are stiffeners, 6 are Exported Cones, 7 is lower margin limits.

Semi-enclosed Exported Cone has voltage stabilizing function to gases at high pressure, so the length strengthening Common Exported cylinder is conducive to gases at high pressure away from cannon and operating personnel, but the length strengthening the power Exported Cone that disappears is conducive to gases at high pressure near cannon and operating personnel, therefore can not strengthen the length of the power Exported Cone that disappears, the drain pressure < leaving area that increasing leaving area can reduce the power Exported Cone that disappears strengthens the increase that must cause Exported Cone volume, according to principle of conservation of energy, gases at high pressure are discharged with less pressure after entering and expanding in larger container, leaving area is larger, exhaust velocity is faster, the less > of drain pressure, reduces potential safety hazard, and method strengthens width and the height of Exported Cone, only have the gases at high pressure of discharging fast in bore, the power Exported Cone of disappearing obtains enough thrust fast could offset barrel inertia force fast, barrel is made to compel fast to stop, therefore the length of the transverse direction outlet of interface cylinder can not be less than 2 times of cannon bore, the leaving area of the power that disappears Exported Cone can not be less than 10 times of horizontal discharge area, so the matching used power of disappearing Exported Cone also will correspondingly lengthen, said lengthening be herein disappear power Exported Cone inside lengthen, but not said outside lengthens the < power Exported Cone that disappears above is high-pressure bottle, its length, width, the increasing at double of its volume and weight must be caused after extended height, therefore its outer surface increases stiffener is very necessary >.The shorter cannon of the barrels such as existing mortar is too little due to the expansion space of gases at high pressure, should not use the power Exported Cone that disappears; When cannon is equipped with and disappears power Exported Cone, barrel and bodywork surface can not have combustibles < if paint, electric wire, oil drum, tire > and breakable object < are as the cloche > of illuminating lamp, take necessary safeguard procedures (such as closing window shooting); As can be seen here, the power that disappears Exported Cone is particularly suitable for the cannon > of more than artillery for suppression <45 times of bore barrel of high power bore barrel.

Such as: " war industry's science and technology " the 7th phase in 2012 is reported, " Ai Faao " 210 millimeters of gun-howitzer combat weights 48 tons that Iraq produces under Canadian experts boolean helps, adopt 52.5 times of bore barrels, range 57.5 km, the shell of transmitting per minute 2 pieces 120 kilograms; It is its inverse recoil result backward in technique that the combat weight of 48 tons, this big gun makes it cannot reach realistic scale, if this big gun adopts inverse recoil muzzle brake and suitably lengthens barrel or increase explosive payload, its weight can reduce to the realistic scale of about 30 tons, its range can break through 60 kms, and the range of 203 millimeters of gun-howitzer 40 kms of 45 times bore barrels more existing than China exceeds half.

The thrust that this programme utilizes automatic gate cutoff high air-flow to obtain offsets the recoil of barrel later stage acquisition, the thrust that the direction of motion utilizing the power Exported Cone that disappears to change high pressure draught obtains offsets the inertia force that barrel obtains in earlier stage, two kinds of methods use barrel to stop recoil fast simultaneously, make gun carriage stressed minimum.Disclosed each scheme is compared, this programme can make cannon cylinder list and lightness and low fault, user can obtain larger income with less investment, there is very high cost effectiveness < particularly life-cycle cost effectiveness >, because the civilian little factory that the extremely low < of the producing cost of this product can produce cylinder assembly of the internal-combustion engine can produce >, the extremely low < of maintenance cost only needs a small amount of machine oil >, the almost nil > of the extremely low < of fault rate.
