1A+M
2A is if increase the mass M of described piston
1, then can reduce M
2, the then power that is subject to of other moving elements, i.e. M
2A reduces.
In conventional engines, because the Quality Design of piston gets very little, piston passes to bent axle and flywheel with the overwhelming majority of the energy of combustion explosion through connecting rod, and when piston needs energy, again energy is refluxed from bent axle and flywheel, so just increased the bearing capacity of system, also increased the power consumption in the energy transfer process, and disclosed Double Tops opposed piston type engine among the present invention, be made as in the larger structure (namely satisfying above-mentioned about power with about the restriction of energy) in the quality with piston, 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, so not only can reduce the bearing capacity of the movement parts that is connected with piston, also can reduce the mechanical loss in the energy flow process.
Double Tops opposed piston type engine disclosed in this invention has changed in the conventional engines design 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 change impact to movement parts (such as connecting rod, bent axle etc.) to reducing reciprocating inertial force and cylinder pressure.
The inventor thinks, in conventional piston formula motor, 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 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, among the present invention the part of the active force of detonation pressure is directly served 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 the design of fixed connecting piece weight thereof, be equivalent to the energy part in the detonation pressure of described cylinder fuel combustion is stored in described piston and the fixed connecting piece thereof with for subsequent use, so just further increase the traveling comfort of mechanism, also improved mechanic efficiency.
Among the present invention, piston in described Double Tops opposed piston type engine is connected with bent axle, the maximum force that 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.
Among the present invention, so-called link refers to the structure that only moves reciprocatingly that is connected with one or more described single top pistons or described Double Tops piston, for the purpose of distinguishing, be divided into category-A link and category-B link, a plurality of described single top piston in wherein said category-A link and the motor links together, and the one or more described Double Tops piston in described category-B link and the motor links together.
So-called structure refers to have the object of certain structure shape and structural strength.
Among the present invention, so-called fluid operating district refers to the zone that fluid can inlet and outlet, and namely according to described piston movement and the zone of volume-variation, a part wherein is the firing chamber.
Among the present invention, so-called forked link refers to that the end of connecting rod is provided with the connecting rod of a plurality of branches connecting body, thereby an end of realizing connecting rod is connected the thing synchronous rotating and is dynamically connected with a plurality of by a plurality of connecting bodys, or is dynamically connected by a plurality of joints synchronous rotating of a plurality of connecting bodys with a quilt company thing.
Among the present invention, when so-called stroke refers to that on the contrary the moving direction of the described piston of same position in two described cylinders is consistent, the described fluid operating of same position district is in opposite working procedure in two described cylinders in four stroke cycle separately, the fluid operating district is in the aspirating stroke stage described in cylinder as described in, and the described fluid operating district of same position then is in expansion stroke in another described cylinder; Or one be in compression stroke, and another is in exhaust stroke.In like manner so-called stroke is identical refers to be in identical working procedure in four stroke cycle separately.
Among the present invention, so-called Double Tops opposed piston type engine should be established suction port and relief opening in the place of necessity according to the known technology of field of internal combustion engine, or establishes suction port, relief opening and air supply opening, and fuel inlet etc.
Among the present invention, according to the known technology in heat energy and power field, necessary parts, unit or system etc. are set in the place of necessity.
Beneficial effect of the present invention is as follows:
It is good that Double Tops opposed piston type engine disclosed in this invention can increase substantially fluid operating district balance quality of shared ratio and mechanism in complete machine, realized the purpose of raising the efficiency under the prerequisite of good reliability; By a plurality of described fluid operatings district is set in motor, and make active force that compressed gas in the described fluid operating district produces piston and the inertial force opposite direction of piston and fixed connecting piece thereof, alleviated the interior gas pressure of described inertial force and cylinder to the impact force of the motion link of piston, and then processing and material requirement to described motion link, the working life of effectively having saved the cost of production of motor and having improved motor have been reduced; By piston mass is further limited, thereby greatly reduced the impact force of explosion pressure to moving elements such as connecting rod, bent axles, the decrease piston mass has also reduced the requirement to the structural strength of each moving element on the impact of engine performance the time, has saved cost of production.
