What install on existing general automobile that just uses and the motorcycle is the two-stroke engine of Overhead valve formula four-stroke engine and crankcase scavenging, though this motor is simple in structure easy for installation, but during the motor work done through air-breathing, compression, work done, four processes of exhaust, a piston in single cylinder promotes a Qu Xuanzhuan, produces power.Use the motor of this form, piston stroke is long, the crank up diameter is big, the motor of this pattern is in operation, it is slow to play speed, power is little, horsepower is not enough, oil consumption is many, move not steady, bring many inconvenience and waste economically to the user, such as: when overtaking other vehicles, use the used time of the automobile of this motor long, the chance of leading the system traffic accident increases, and this phenomenon of traffic accident that causes because of overtaking other vehicles is very general, so, present this overhead valve engine can not satisfy the usage requirement of current automobile, and secondly, automobile travels in the plains region, if the design speed per hour of automobile is per hour 120 kilometers, the the highest power that per hour can only reach 100 kilometers explanation motors is little, and therefore, the motor of this pattern fails to reach the power of the required usefulness of automobile F-Zero.Moreover, when automobile goes up a slope, necessary kickdown, open the throttle, like this, engine speed is very high, but the travelling speed of automobile is slow, not only fuel consumption is big, and has increased the running time of automobile, for concerning the user, promptly improved expense, having reduced efficient again, also is a kind of waste to the petroleum resources of China, so it is imperative to change the motor of nearly this pattern.
The purpose of this utility model, be to want to provide a kind of novel every cylinder double-piston horizontal positioned yi word pattern opposed engine, the motor volume of this pattern can not increase, because so horizontal positioned is easier for installation, it has good power performance and economic benefit, to replace now common overhead valve engine, satisfy the demand of entire society to superior motor.
The utility model is that the composition of the existing common four-stroke engine realized like this is by body, connecting rod, distribution device, lubricating system, fuel supply system, cooling system, igniting system composition such as grade.
The structural type of new work engine has very big change, mainly in the following aspects.
1, the body of common four-stroke engine comprises a cylinder block, a cylinder head, crankcase and oil pan.
Different is: new work engine is that two crankcases are arranged on each body, and it does not have cylinder head, just has two to be the distribution side cover that distribution made.

What install on our employed gas car and the motorcycle at present, is four-journey and two-stroke engine.Piston reciprocal four one way in cylinder are finished air inlet, compression, work done, four processes of exhaust and are called four-stroke engine, and piston reciprocal two one way in cylinder are finished air inlet, and the motor of compression work done, four processes of exhaust is called two-stroke engine.
When four-stroke engine and two-stroke engine work done, the piston in the cylinder has two stops equally, is respectively top dead center and lower dead center.
Top dead center is that piston is from farthest, crank up center.
Lower dead center be piston from the crank up center the most nearby.
Two-stroke engine and four-stroke engine possess same four cyclic processes and working principle, now identical with the working principle explanation of two-stroke engine and new work engine.
Air-breathing, air inlet and three ducts of exhaust are arranged on the cylinder wall of two stroke single-cylinder engines, a crankcase and a bent axle are arranged, a piston is arranged in the cylinder, and a cylinder head is arranged.
The novel single cylinder two-stroke engine that I am designed, six ducts are arranged on its cylinder wall, be respectively two suction ports, two inlet holes and two exhaust ports, the corresponding two ends of its cylinder are provided with two identical crankcases and two identical bent axles, two corresponding ends of bent axle respectively are equipped with a Positioning Gear of the identical identical number of teeth mutually, make the running relatively simultaneously of two bent axles.Two pistons are housed in the cylinder simultaneously, and the stroke of two relative works done of piston is arranged in the cylinder.Electrical spark takes place in spark plug when two-piston is compressed near top dead center, the mixed gas of outburst directly promotes two pistons.
Three holes on the existing common two-stroke engine cylinder wall can be sealed by piston certain respectively constantly, suction port communicates with Carburetor, inflammable mixture can enter crankcase by suction port, can enter in the cylinder through inlet hole more again, and waste gas is then discharged through exhaust port.
Six ducts of new work engine that different is respectively certain moment by two piston closes, its two suction ports communicate with Carburetor, inflammable mixture enters two crankcases at cylinder two ends respectively from two suction ports, enter through two inlet holes again, in the same cylinder, the waste gas that is produced is then discharged by two exhaust ports respectively.
Two working strokes of existing common engine and new work engine.
First stroke.The piston of existing common engine is moved to top dead center by lower dead center, exhaust port and inlet hole have been sealed earlier, then, compression has charged into the flammable mixed air in the cylinder of piston top, and when piston was abdicated suction port, inflammable mixture was owing to the degree of vacuum of piston below form is inhaled in the crankcase, when treating that piston moves to top dead center, spark plug generation electrical spark is lighted compressed inflammable mixture, and the outburst work done takes place.
First stroke of new work engine, two-piston is relatively moved to top dead center simultaneously by lower dead center, seals two exhaust ports and two inlet holes earlier, then, compression has charged into the mixed gas in the cylinder between the two-piston, simultaneously, inflammable mixture, the vacuum that forms owing to the two-piston below is inhaled into two crankcases, when two pistons walk near top dead center, two draw together the spark plug generation electrical spark on the plug opposite position cylinder wall, light compressed inflammable mixture, the outburst work done.
Second stroke of existing common two-stroke engine.Piston is subjected to breaking out the promotion of gaseous-pressure, move to lower dead center by top dead center, drive the bent axle work done by connecting rod, when piston is abdicated exhaust port and inlet hole, the waste gas of cylinder is scurried out from exhaust port because the pressure of itself is higher on the one hand, on the other hand, the mixed gas in the crankcase is subjected to the pressure effect of piston below, and clamp-ons in the cylinder from inlet hole.Simultaneously, also work to drive away residual gas.
Different is: the two-piston of new work engine is subjected to breaking out the promotion of gaseous-pressure, by top dead center when lower dead center moves, drive two crankshaft rotating works done by two connecting rods, after the combustion, connect together by the Positioning Gear of two bent axle opposite ends rotating force, and make two bent axles continue rotation by same angle with two bent axles.When piston was abdicated two exhaust ports and two inlet holes, the waste gas in the cylinder will be discharged from two exhausts, and the inflammable mixture in two crankcases then is subjected to the pressure effect of two-piston below, and is entered in the cylinder by two inlet holes.Work done and two processes of ventilation have also just been finished.
Existing common engine is to promote a piston by explosive force, drive a crankshaft rotating by a connecting rod, new work engine is to utilize explosive force to promote two pistons, drive two crankshaft rotating by two connecting rods, with two Positioning Gears two rotating forces by axle are connected together again, become the total output of motor.
This new work engine be better than existing common engine have following some:
First point: comparing with existing common engine, under the air displacement situation identical with cylinder bore, the two-piston stroke sum of new work engine equals the stroke of existing common engine piston.The stroke of every piston of new work engine equals half of existing common engine piston stroke, during the motor work done, if the motion speed of piston is constant, so, the time that merit of the every work of new work engine needs just now common engine do merit need be with 1/2nd of the time, like this, just accelerate the work done number of times of new work engine, equaled to increase the power of new work engine.
Second point: in existing each cylinder of common engine a piston is arranged, and two pistons are arranged in each cylinder of new work engine, when cylinder bore is identical, the summation of new work engine piston area equals two times of existing common engine piston area, during the motor work done, explosive force promotes two pistons rapidly, thereby, increased the power of motor, it is fast to make new work engine play speed than existing common engine.
Thirdly: the motor of this pattern, piston stroke is short, and the crank up diameter is little, and the abrasion that has reduced parts such as piston-cylinder and bent axle has increased the service time of motor.
The 4th point: the power of new work engine is big, and transmission and power character are strong, and abrasion is little, and in the unit time, when new work engine was identical with existing common engine rotating speed, the fuel that new work engine is used than existing common engine lacked, and the motor of this pattern is fuel-efficient.
The 5th point: during common engine work done now, the bent axle of motor can produce unbalanced vibration, during the new work engine work done, it is equipped with two bent axles, and control mutually with Positioning Gear, making their runnings relatively simultaneously, the vibration force that two bent axles produce will be hanged down mutually and be disappeared.Motor is operated steadily.
The 6th point: during common engine work done now, the focus that directly is subjected in the cylinder has three, one is that cylinder wall, one are that cylinder head, one are piston-top surfaces, new work engine does not have cylinder head, so directly be subjected to focus to have only two, one is that cylinder wall, one are pistons, and new work engine has reduced and externally is subjected to focus, has reduced the heat dissipating capacity of attached heat sinks.
This new work engine has characteristics such as the fuel consumption fraction horsepower is big, abrasion is little, a speed is fast, power is big, operate steadily, it has broken the history of having only a piston in each cylinder of common engine, the success of this pattern motor, to become the predecessor who improves the present internal-combustion engine that generally uses of China, if the motor by the related internal-combustion engine manufacturing of the utility model patent will be a new change of China's internal-combustion engine, make the internal-combustion engine of China walk prostatitis, use the industrial or agricultural of internal-combustion engines that powerful impetus is arranged all in the world.
