Specific embodiment
The invention will be further described with reference to the accompanying drawings and embodiments.
As shown in Figure 1 to Figure 5, the present embodiment is used for the double-piston connection rod set of engine, inhales naturally in existing single cylinder
On the basis of the horizontal four-cycle diesel engine single-piston of gas, piston is improved, improved piston is double-piston.
Piston connecting rod unit includes piston 1, piston ring 2, piston pin 3, connecting rod 4 and connecting rod bearing shell 5.
Piston includes first piston 11 and second piston 12, and described 4 one end of connecting rod connects connecting rod bearing shell 5,4 other end of connecting rod
Equipped with the first connecting hole 41 and the second connecting hole 42, it is respectively used to connection first piston 11 and second piston 12.Connecting rod 4 and piston
1 is connected by piston ring 2, is limited by piston pin 3.The first connecting hole 41 and the second connecting hole 42 of connecting rod 4 are along 4 axis of connecting rod
The symmetrical golden section distribution of diameter.First piston 11 and the first connecting hole 41 are installed using the inclination angle of 25 ° of angles, to cylinder wall
Tension reduces, and improves the work doing efficiency of thrust gas.
Illustrate principle and advantage that first piston 11 and second piston 12 are connected on the same connecting rod 4 below:
Thrust principle of stacking can significantly improve the power of engine, and the power of two relative motions is mutually collided in B point, stop at
G point, F are the acting thrust of A, and B reacts on power F, stops at G point, and A point is B point reaction force in F, moves to G point from B point
Unit time in F power move distance.Pressure W suffered by so G point are as follows:。
Thrust superposition must have counter-movement power or counter-movement trend, reasonable to design first piston 11 according to thrust principle of stacking
The thrust of engine can be overlapped with second piston 12.
When the 1 downlink work done of gas push piston, 4 due east direction of connecting rod is moved upwards, and forms counter-movement trend.This puts
For the G point of connecting rod 4, G point terminates counter-movement trend when connecting rod 4 moves to 3 o'clock direction.
As shown in figure 3, connecting rod 4 pushes crankshaft to be operating clockwise, G when gas push first piston 11 moves downward
Point is moved upwards power, is pushed first piston 11 to drive in the wrong direction, form counter-movement power, generated by second piston 12, the support generation of B point
Superposed force, superposed force act on connecting rod 4 simultaneously, and connecting rod 4 obtains the thrust of first piston 11 and the reaction force of second piston 12
Dual thrust, double piston engine make the thrust of engine generate superposition by lever principle.
The resistance that double piston engine is loaded to 75 kg, according to 3000 r/min of rated speed, measuring load speed is
2720 r/min.According to Calculating Torque during Rotary formula:
Because of 4.2 kw of nominal power, 3000 r/min of rated engine speed of the engine selected:
,
,
Conclusion can be obtained from above: the power of double piston engine is 1.78 times of common engine power, the dual-active for engine
The power of engine can be improved in plug connection rod set.
Since the first piston 11 of the double-piston connection rod set for engine takes the inclination angle for fixing 8 ° to install, to cylinder wall
Tension it is opposite reduce, to improve the work doing efficiency of thrust gas.Since first piston 11 and connecting rod 4 have 8 ° of inclination angle,
The tension that second piston 12 generates cylinder right wall cancels out each other work to the tension that cylinder wall generates in piston rod operation
With.
The depth pistion of double piston engine is opposite to be reduced, and mistake refers to the intersection of position and the attached oily function of mid-section, makes the
One piston 11 and second piston 12 have sufficient uniform lubricating condition.
The big stroke introduction of the four of the connection rod set engine of double-piston:
1) expansion space stroke
After the completion of gas pressuring stroke, gas combustion explosion generates powerful gas pressure, pushes 1 downlink work done of piston, and crankshaft is from 12
O'clock, direction to 3 o'clock direction did operating clockwise.Second piston 12 pushes first piston 11 to drive in the wrong direction by leverage at this time
Superposed force is generated, when Crankshaft motion is to 3 o'clock direction, first piston 11 does not go downwards to the middle position of cylinder, is in more
Anticyclonic state, this just make crankshaft 3 o'clock direction obtain bigger gas pressure, generate more high thrust torque.Crankshaft is from 3
O'clock direction to 6 o'clock direction move when superposed force disappear, under first piston 11 accelerates under the leverage of second piston 12
Row, but crankshaft 3 o'clock direction equally obtain bigger gas pressure, also produce bigger thrust moment, crankshaft reached for 6 o'clock
Work done is completed when direction.
2) instroke
Enter instroke after the completion of engine power stroke, at this time piston stroking upward, due to the leverage of second piston 12
To the reaction force of 11 uplink of first piston, reduce the speed uplink of first piston 11, to reduce the resistance of 1 uplink of piston
Power decreases the energy loss of accumulator.When crankshaft runs to 9 o'clock direction, the reaction force of lever makes first piston
It is about to exhaust gas in 11 acceleration to drain.And 1 connecting rod of piston has generated centrifugal force at this time, the acceleration uplink of piston 1 also reduces simultaneously
The negative interaction power of centrifugal force.The discharge of gas also complies with the rule of the motion of matter from slow to fast from slow to fast.
3) suction stroke
Inlet valve is opened, crankshaft band piston downlink, bent because the leverage of second piston 12 slows down 11 downlink of first piston
First piston 11 is accelerated downlink by the active force of second piston 12 when axis reaches 3 o'clock direction, and first piston 11 has acceleration at this time
The effect of air-breathing, air inlet from slow to fast, meet the characteristics of motion of substance.
4) compression travel
IC Intake Valve Closes after the completion of air-breathing, crankshaft compress uplink by 6 o'clock direction.Since the lever of second piston 12 is made
With, slow down 11 speed uplink of first piston, reduce the resistance of 1 uplink of piston, while decrease accumulator energy damage
Consumption.From 9 o'clock direction, first piston 11 accelerates uplink, until cylinder head, by gas compression to terminal.
