Abstract
The super expansion circulation internal combustion engine has two main cylinders in the same caliber and one subsidiary cylinder in relatively larger caliber. Two main cylinders on two sides of the subsidiary cylinder has work phase difference of 360 deg, and the subsidiary cylinder has piston motion direction opposite to that of the main cylinders and distance between the link rod axle neck and the main axle neck greater than the distance between two main cylinders. Two main cylinders have their induction stroke, compression stroke and expansion stroke the same as conventional internal combustion engine but different exhaust stroke. Their exhausted gas is first exhausted into the subsidiary cylinder and further expanded before exhausted from the subsidiary cylinder, and this makes the engine obtain excessive power and raised oil burning efficiency.
Description
Affiliated technical field:
The present invention relates to the power plant of a kind of burning diesel oil or gasoline, relate in particular to the super expansion cycle explosive motor of a kind of burning diesel oil or gasoline.
Background technique:
Present four-stroke ic engine, each cylinder are finished work cycle needs four strokes: air-breathing, compression, expansion, exhaust.Have only expansion stroke externally to make positive work in four strokes.Although because the improvement of the every aspects such as extensive employing of electronic control technology makes internal-combustion engine technology be in a higher level, its effective power output generally only accounts for 1/3rd of fuel total energy.Other has 1/3rd energy to be taken away by waste gas, and waste gas when exhaust valve is discharged because temperature, overpressure often with harsh noise, are the main sources of internal combustion engine exhaust gas noise.
Summary of the invention:
The present invention is not changing under the situation that does not influence explosive motor suction stroke, compression stroke, expansion stroke work in other words, the improvement that exhaust stroke is carried out.Earlier waste gas is entered in the bigger cylinder of volume ratio, after further expanding, from this big cylinder, enter outlet pipe again.This improvement, the corresponding expansion stroke that prolonged can make explosive motor export more power.
The invention has the beneficial effects as follows, can improve the efficient of explosive motor, reduce the consumption of fuel oil, reduce the noise of exhaust.
In order to clearly demonstrate the technical characterstic of this programme,, and in conjunction with the accompanying drawings, this programme is set forth below by a specific embodiment.
Description of drawings:
Accompanying drawing is the bent axle and the combustor section separation structure schematic representation of the embodiment of the invention.Other parts are identical with present explosive motor situation, so do not mark.
Among the figure, 1. master cylinder, 2. master cylinder, 3. countercylinder, 4. piston, 5. piston, 6. piston, 7. suction tude, 8. suction tude is 9. losed heart, and 10. loses heart 11. intake valves, 12. exhaust valves, 13. intake valves, 14. outlet pipe, 15. exhaust valves, 16. intake valves, 17. exhaust valves, 18. intake valves, 19. bent axles.
Embodiment:
Master cylinder (1) is identical with the cylinder bore of master cylinder (2), and the diameter of countercylinder (3) is greater than the diameter of master cylinder (1) and master cylinder (2).Master cylinder (1) and master cylinder (2) are distributed in the both sides of countercylinder (3) near array.The work phase difference of two master cylinders is 360 °.The rod journal of countercylinder becomes 180 ° of arrangements with the rod journal of two master cylinders, and the piston of secondary cylinder is opposite with the piston motion direction of two master cylinders.The rod journal of secondary cylinder and the distance of main journal, bigger than the distance of two master cylinders, make the summit of the top dead center of the piston (6) in the countercylinder (3) near cylinder.Two master cylinders communicate with secondary cylinder by lose heart (9), lose heart (10) respectively, and all there is valve at the two ends of losing heart.In addition, two master cylinders all intake valve by separately communicate with suction tude, and secondary cylinder then communicates with outlet pipe by an exhaust valve.
Two master cylinders all have suction stroke, compression stroke, expansion stroke, exhaust stroke, and secondary cylinder has only expansion stroke and exhaust stroke.The situation of the suction stroke of two master cylinders, compression stroke, expansion stroke and present popular explosive motor is identical, but it is not directly to be discharged to outlet pipe by exhaust valve that journey is filled in exhaust, but loses heart and the intake valve of secondary cylinder correspondence enters secondary cylinder by exhaust valve, one.Because their phase relationship, when one of them in two master cylinders began exhaust, secondary cylinder piston all just in time was in top dead center, because the diameter of secondary cylinder is greater than master cylinder, the corresponding rod journal and the distance of main journal are also big, so the waste gas of master cylinder enters the process that the process of secondary cylinder is an expansion.The positive work that waste gas is done secondary cylinder piston is greater than the negative work of waste gas to the master cylinder piston work, so this process is externally exported positive work.When the up exhaust of master cylinder piston during near top dead center, the exhaust valve of secondary cylinder is opened, and at the exhauxt valve opens initial stage, waste gas has an of short duration free exhaust stage.After free exhaust finished, in-cylinder pressure reduced greatly, and the piston of master cylinder also arrives top dead center immediately, and the master cylinder exhaust process finishes, and its exhaust valve is closed.The intake valve of secondary cylinder correspondence also is closed.This moment, this master cylinder is finished a circulation and is about to enter next circulation.Afterwards, secondary cylinder piston stroking upward forced exhaust, when arriving top dead center, secondary cylinder exhaust valve closing, secondary cylinder is finished once circulation.
Secondary cylinder carries out above-mentioned cycle period, and second master cylinder successively finished compression stroke, expansion stroke.Next, secondary cylinder is finished identical circulation with another master cylinder cooperation by above-mentioned same process.Alternately, explosive motor just can turn round down continuously before and after two master cylinders.
In addition, waste gas is by after the above-mentioned expansion again, and temperature, pressure further reduce, when secondary cylinder is discharged, and the also corresponding reduction of exhaust noise.
