Many pistons conllinear cylinder piston mechanism disclosed in the utility model has changed as far as possible with the light-weighted design philosophy of piston, opposite with it, by with piston or its fixed connection structure body weight Quantitative design, thereby reduce reciprocating inertial force and cylinder pressure changes (detonation pressure that burning forms during in particular as reciprocating engine) to the impact of movement parts (such as connecting rod, bent axle etc.).
The inventor thinks, in traditional cylinder piston mechanism, such as reciprocating engine etc., the detonation pressure that cylinder fuel combustion produces acts on the piston and link thereof of lighter weight, form larger acceleration, the part of energy is stored in the flywheel the most at last, when cylinder piston mechanism needs energy, discharged by flywheel again and get back in the cylinder piston mechanism, a plurality of parts have been passed through in the energy storage of so long distance and release, more pass through the many places slip or rotated the interface, must cause the weight of energy loss and whole mechanism.In contrast, to be in the part of the active force of detonation pressure in the fluid operating district in the burning expansion expansion stroke in the utility model directly as the compressive force in other described fluid operating districts, this has just improved stationarity, efficient and the complete machine lightweight of mechanism greatly.Moreover, by with described piston and fixed connection structure body weight Quantitative design thereof, be equivalent to the energy part in the detonation pressure of described cylinder fuel combustion is stored in described piston and the fixed connection structure body thereof with for subsequent use, so just further increase the traveling comfort of mechanism, also improved mechanic efficiency.

, the common acceleration of described piston and other moving elements is
Figure 931817DEST_PATH_IMAGE016
, maximum explosion pressure is , then have relation
Figure 599428DEST_PATH_IMAGE018
In the conventional engines, because the Quality Design of piston is very little, namely The power very little, that the movement parts that therefore is connected with piston is born
Figure DEST_PATH_IMAGE019
Very large, increased the requirement to the bearing capacity of the movement parts that is connected with piston.
And disclosed many pistons conllinear cylinder piston mechanism in the utility model is made as in the larger structure (namely satisfying above-mentioned about power with about the restriction of energy) in the quality with piston, owing to increasing the quality of described piston, namely increases , the power that the movement parts that therefore is connected with piston is born
Figure 380936DEST_PATH_IMAGE019
Reduce.The part of the energy of combustion explosion or major part are stored in the piston, when piston needs energy, can directly with the movement velocity that reduces oneself energy be discharged, thereby reduce the requirement to the bearing capacity of the movement parts that is connected with piston, and can reduce the mechanical loss in the energy flow process.
For example, in described many pistons conllinear cylinder piston mechanism and structure that bent axle is connected, the maximum force that described bent axle bears equals poor to the active force of described piston and to-and-fro motion maximum inertia force of gas in the cylinder, and this has just greatly alleviated crankshaft main journal, rod journal, wrist-pin end of connecting rod and has connected the impact force that axle journal etc. is located.
In the utility model, so-called cylinder piston mechanism refers to for the cylinder piston mechanism of reciprocating engine or is used for the cylinder piston mechanism of piston gas compressor or is used for the expand cylinder piston mechanism of acting mechanism of piston type.

In the conventional engines, if the fuel oil injection advance angle is increased (referring to diesel engine) or ignition advance angle increase (referring to petrol engine), maximum explosion pressure in the cylinder will occur near in the zone of top dead center, this will cause very large load to the connection part of rod journal, connecting rod and the piston of bent axle and the connection part of connecting rod and bent axle, even failure.And many pistons conllinear cylinder piston mechanism disclosed in the utility model, because the reciprocating inertial force of described piston and fixed connecting piece thereof is very large, particularly when the reciprocating inertial force of described piston and fixed connecting piece thereof during greater than the maximum explosion pressure in the cylinder, not only can not increase the rod journal of bent axle, the load of the connection part of the connection part of connecting rod and piston and connecting rod and bent axle, its load is reduced, and in the fuel combustion exothermic process, can make the under high pressure heat release of more fuel, improve described many pistons conllinear cylinder piston mechanism as the efficient of motor (diesel engine or petrol engine).
In the utility model, should in the case of necessary described piston be made as the Double Tops piston according to known technology.In general, other the described pistons in a plurality of described pistons except the described piston at two ends should be made as the Double Tops piston, can reduce the space that described piston occupies like this.
In the utility model, according to the known technology in gas compression and heat energy and power field, necessary parts, unit or system etc. are set in the place of necessity.
The beneficial effects of the utility model are as follows:
Many pistons conllinear cylinder piston mechanism disclosed in the utility model can increase substantially fluid operating district shared ratio in complete machine, and then raises the efficiency, and the decrease piston mass is on the impact of cylinder piston mechanism performance.
