Abstract
A variable-stroke cylinder piston (1) of a cylinder type internal combustion engine. A connecting shaft (3c) of a connecting rod (3) is connected to the piston (1) through an elongated hole (1a) in the piston (1). The connecting shaft (3c) of the connecting rod can not only rotate in the elongated hole (1a) in the piston, but also slide freely along the elongated hole (1a). When the piston (1) works in the intake stroke, under the effect of the negative pressure of gas in a cylinder (2), the connecting rod (3) is driven by a crankshaft (4) to move, and the connecting shaft (3c) slides from the near end to the far end in the elongated hole (1a) in the piston to drive the piston to work, so that the intake stroke of the cylinder (2) is relatively shortened. When the piston (1) works in the exhaust, compression and power strokes, under the effect of the positive pressure of gas in the cylinder (2), the connecting shaft (3c) in the elongated hole (1a) in the piston returns to the near end of the elongated hole (1a) in the piston, so that the intake stroke of the piston is relatively shortened as compared with the power stroke, and therefore more pressure of gas resulting from expansion after each combustion of the engine is converted into power. The variable-stroke cylinder piston has the beneficial effects of small fuel consumption, high power efficiency, and the like.
Description
本发明涉及一种以提高气缸型内燃发动机的燃料使用效率为目的，所进行针对其气缸活塞结构的机械领域的设计和改进。从而设计出一种气缸型内燃发动机可变行程气缸活塞。The present invention relates to a design and improvement of a mechanical field for a cylinder piston structure thereof for the purpose of improving the fuel use efficiency of a cylinder type internal combustion engine. Thus, a cylinder type internal combustion engine variable stroke cylinder piston is designed.
一般现有内燃发动机都有吸气、压缩、做功、排气个四冲程，空气通过活塞完成吸气和压缩冲程，其体积被压缩了几倍到几十倍并同燃料混合，当其被点燃爆发后，其体积会在原来的基础上再膨胀几十倍，这样膨胀的气体推动推动活塞运动做功。由于一般现有的内燃发动机的活塞在吸气、做功、排气、压缩的工作行程都是相等的，其膨胀气体所产生的气压只能有一部分用于做功，其余的被消音器、排气管等消耗，然后排放掉了。试想：发动机工作时，气缸内每一次气体燃烧膨胀后，若气缸活塞吸气和做功的行程为X，气缸内膨胀的燃爆气体平均压力为1，推动活塞做功为100％的话；如果活塞做功行程为2X，气缸内燃爆气体压力虽减少至50％，但做功增加50％；当活塞做功行程为3X，气缸内燃爆气体压力减少至33％，做功又增加33％；当活塞做功行程为4X，气缸内燃爆气体压力减少至25％，做功又增加25％；这样活塞做功行程增加了3倍，其总做功＝100％+50％+33％+25％＝208％。由此可见，通过这一途径可将每一次燃烧后膨胀的气体压力更多地转化成做功，实现内燃发动机功效成倍增长，因此本发明可以设计成：使活塞吸气的行程为做功行程的几分之一或活塞做功的行程比吸气行程大几倍，至于多少倍为最合理，是下一步研究的课题。Generally, existing internal combustion engines have four strokes of suction, compression, work, and exhaust. The air completes the suction and compression strokes through the piston, and its volume is compressed several times to several tens of times and mixed with the fuel when it is ignited. After the explosion, its volume will expand several times on the original basis, so that the expanding gas pushes the piston to do work. Since the pistons of the existing internal combustion engines are equal in the working strokes of suction, work, exhaust, and compression, only a part of the air pressure generated by the inflation gas is used for work, and the rest are silenced and exhausted. The tube is consumed and then drained. Imagine: when the engine is working, after each gas combustion in the cylinder is expanded, if the stroke of the cylinder piston inhaling and working is X, the average pressure of the explosive gas in the cylinder is 1 and the piston is working 100%; if the piston works The stroke is 2X, the internal combustion gas pressure in the cylinder is reduced to 50%, but the work is increased by 50%; when the piston work is 3X, the internal combustion gas pressure is reduced to 33%, the work is increased by 33%; when the piston is 4X The internal combustion gas pressure in the cylinder is reduced to 25%, and the work is increased by 25%; thus the piston work stroke is increased by 3 times, and the total work is 100% + 50% + 33% + 25% = 208%. It can be seen that through this way, the gas pressure of each post-combustion expansion can be more converted into work, and the efficiency of the internal combustion engine is multiplied. Therefore, the present invention can be designed such that the stroke of the suction of the piston is the work stroke. A fraction of the piston or the stroke of the piston is several times larger than the suction stroke. As for how many times is the most reasonable, it is the subject of further research.

2.可变行程-E与气缸型内燃发动机的参数之间逻辑关系：2. The logical relationship between the variable stroke-E and the parameters of the cylinder type internal combustion engine:
压缩比＝(A+D-E)/A；Compression ratio = (A + D - E) / A;
气缸排气量＝(A+D)×R×R×π；
Cylinder displacement = (A + D) × R × R × π;
气缸吸气量＝(A+D-E)×R×R×π；Cylinder intake amount = (A + D - E) × R × R × π;
排气量与吸气量之比称为排吸比＝A+D/(A+D-E)。The ratio of the amount of exhaust to the amount of inhalation is called the discharge ratio = A + D / (A + D - E).
其中：A为活塞压气表面与缸顶压缩之后之间的距离；D为曲轴轴心的回转直径；R为气缸内圆半径。Where: A is the distance between the piston pressure surface and the cylinder top compression; D is the rotation diameter of the crankshaft axis; R is the cylinder inner circle radius.

由于本发明是在现有传统气缸型内燃发动机的气缸活塞上进行构造改进，适用性显而易见不虞赘述。Since the present invention is a structural improvement on the cylinder piston of the conventional conventional cylinder type internal combustion engine, the applicability is obviously not described.
4.3先进性效能分析4.3 Advanced performance analysis
以直径100单缸气缸型内燃发动机为原机：设其发动机：A＝10mm；D＝100mm；压缩比＝10∶1；排气量＝吸气量。Take the diameter of 100 single cylinder cylinder type internal combustion engine as the original machine: set its engine: A = 10mm; D = 100mm; compression ratio = 10:1; exhaust volume = intake.
以原机进行改造换用气缸型内燃发动机可变行程气缸活塞(1)，称之为-改进机：设其发动机：Ag＝2.5mm；D＝100mm；活塞的可变行程E＝75mm；连杆增加长度为A-Ag＝10mm-2.5mm＝7.5mm，压缩比＝(Ag+D-E)/Ag＝10∶1；排吸比＝Ag+D/(Ag+D-E)＝4∶1，即排气行程是吸气行程的4倍，吸气量是排气量的1/4，其他不变。试想：当发动机工作时，气缸内每一次气体燃烧膨胀后，若气缸活塞吸气和做功的行程为X，气缸内膨胀的燃爆气体平均压力为原机1/4，推动活塞做功为1的话；如果活塞做功行程为2X，气缸内燃爆气体压力虽减少至1/2，但做功增加1/2；当活塞做功行程为3X，气缸内燃爆气体压力减少至1/3，做功又增加1/3；当活塞做功行程为4X，气缸内燃爆气体压力减少至1/4，做功又增加1/4；这样活塞做功行程增加3倍，其总做功量＝1/4*(1+1/2+1/3+1/4)＝25/48，如果原机和改进机吸入的空气和燃料的比例不变，改进机做功虽是原机的25/48，但改进机所消耗的燃料是原机的1/4，从价值工程的观点上看是可以接受的。如果改进机的气缸加大，使吸入的空气和燃料的容量增加1倍，改进机与原机做功相等，但改进机所消耗燃的料是原机的1/2，其先进性显而易见。Renovation with the original machine to replace the cylinder type internal combustion engine variable stroke cylinder piston (1), called - improvement machine: set its engine: Ag = 2.5mm; D = 100mm; piston variable stroke E = 75mm; The length of the rod is increased by A-Ag=10mm-2.5mm=7.5mm, the compression ratio=(Ag+DE)/Ag=10:1; the suction ratio=Ag+D/(Ag+DE)=4:1, ie The exhaust stroke is 4 times the intake stroke, and the intake is 1/4 of the displacement, and the others are unchanged. Imagine: When the engine is working, after each gas combustion in the cylinder is expanded, if the stroke of the cylinder piston inhaling and working is X, the average pressure of the explosive gas in the cylinder is 1/4 of the original machine, and if the piston is doing 1 work, If the piston stroke is 2X, the gas pressure in the cylinder is reduced to 1/2, but the work is increased by 1/2; when the piston is 3X, the pressure of the gas in the cylinder is reduced to 1/3, and the work is increased by 1/ 3; When the piston's work stroke is 4X, the cylinder's internal combustion gas pressure is reduced to 1/4, and the work is increased by 1/4; thus the piston's work stroke is increased by 3 times, and its total work volume = 1/4* (1+1/2) +1/3+1/4)=25/48, if the ratio of air and fuel inhaled by the original machine and the improved machine is the same, the machine work of the improved machine is 25/48 of the original machine, but the fuel consumed by the machine is A quarter of the original machine is acceptable from a value engineering point of view. If the cylinder of the improved machine is increased, the capacity of the inhaled air and fuel is doubled, and the improvement machine is equal to the work of the original machine, but the fuel consumed by the improved machine is 1/2 of the original machine, and its advancement is obvious.
