Conversely, in order to reduce fuel consumption and shorten the piston stroke to make the cylinder volume smaller, the length of the crank must also be shortened accordingly, which will also make the torque output by the engine smaller.

example 1
[0025] Example 1, when D 1 =90mm, D 3 =55mm, S=D 1 / 2, find D 2
[0026] According to the calculation formula: 90+55-D 2 =90 / 2
[0027] D. 2 =90+55-90 / 2
[0028] D. 2 =100mm
example 2
[0029] Example 2, when D 1 =90mm, D 2 =80mm,D 3 =55mm, find S
[0030] Set according to the calculation formula: S=90+50-80=65mm
example 3
[0031] Example 3, when D 1 = 90mm, D 2 =80mm,D 3 =50mm, find S
[0032] Set according to the calculation formula: S=90+50-80=60mm
[0033] Example 4. When S=70mm, D 2 =90mm, D 3 =60mm, find D 1
[0034] According to the calculation formula: D 1 +60-90=70
[0035] D. 1 =70+90-60
[0036] D. 1 =100mm
[0037] By example 1, example 2, example 3, it can be understood that D of the present invention 2 than D 3 The larger, the smaller S, such as D 2 The smaller, the larger S, such as D 3 The smaller is, the smaller S is. In addition, it can be seen from the calculation that to realize the present invention, D 2 >D 3 and D 2 1 +D 3 , because, when D 2 =D 3 Then S=D 1 , and when D 2 =D 1 +D 3 Then S=0. Partial hole neck sleeve (16) and crankshaft (5) among the present invention can also be implemented like this respectively:

Abstract
The invention relates to a new high efficient energy conservation reciprocal motor, which is composed of crank connecting rod system (24) with cylinder (1), piston (2), connecting rod (3)and bent axle (5), wherein the connecting rod (3) amplitude of oscillation is small; and the length of travel about piston (2) is twice length less than crank (4); fixing the connecting rod large-end center of circle (21) on the line (9) between connecting rod axial center (8) and bent axle (5) axial center (7); adapting axial center (8) of connecting rob large-end (19) to move revolution around bent axle (5) axial center (7) and the connecting rod large-end center of circle (21) to turn around rotating center simultaneously in the crank connecting rod system (24) operation course; realizing small amplitude of oscillation and twice length less than piston (2) travel by the steering variation of missing distance (31) between connecting rod axial center (8) and connecting rod large-end center of circle (21). The motor is fit for reciprocal piston two-cycle and four-cycle engine and pump of gasoline, diesel motor and so on.
Description
Technical field: [0001] The invention relates to a reciprocating piston engine with a crank connecting rod mechanism in which the connecting rod shaft is revolving in the large end of the connecting rod, especially an engine with a small connecting rod swing and a piston stroke less than twice the crank length. Background technique: [0002] At present, reciprocating piston engines mostly use a crank-connecting rod mechanism. In this mechanism, there is only one cylindrical connecting rod shaft on the crank that receives and transmits the interaction force between the connecting rod and the crank. The big end of the connecting rod, and the other end of the connecting rod is connected to the piston through the piston pin. The connected connecting rods are rigid, which also keeps the distance between the piston and the axis of the connecting rod constant, so the connecting rod swing of the reciprocating piston engine adopting this kind of crank-connecting rod mechanism is larg...
