Technical background:

Prior art: patent 03227049.6 hyperbolic axle internal-combustion engine adopts lengthening cylinder length, respectively pacify one group of piston crank mechanism in left and right of horizontal cylinder, in the left and right crankcase of body, respectively be equipped with a bent axle, crankshaft output end is equipped with and middle output shaft gear meshed gears, there is porting at place, firing chamber, cylinder middle part, be equipped with cylinder head above the porting, when fuel at firing chamber, cylinder middle part explosion time, promote left and right bent axle piston crank mechanism acting. and output shaft in the middle of power passed to.Shortcoming is it under the when equal gettering quantity situation of identical compression, and output power does not reach optimization.

Summary of the invention

The purpose of this utility model is to provide a kind of asynchronous hyperbolic axle internal-combustion engine that can significantly improve power and fuel availability under the when equal gettering quantity situation of identical compression of comparing with patent 03227049.6.

The utility model adopts following manner to achieve the goal: left and right major-minor cylinder is set is connected, one group of major and minor piston crank mechanism of wherein corresponding installation, in the left and right crankcase of body, respectively be equipped with bent axle, two crankshaft output ends are equipped with gear and are meshed with middle output shaft gear, wherein the tooth radius on the main crankshaft is the twice of secondary crankshaft tooth radius, be that gear on the main crankshaft rotates a circle, the secondary crankshaft gear rotated for two weeks.Master cylinders top combustion chamber place is provided with porting, cylinder head is installed above the porting, the auxiliary steam cylinder top is provided with spark plug or oil nozzle, when fuel at the firing chamber explosion time, promoting left and right bent axle piston crank mechanism acting. power output can also can be exported by main shaft or countershaft as required by jack shaft output.The big I of major-minor piston is inconsistent.

The gettering quantity of design master cylinders of the present utility model is this machine air displacement, compare under the when equal gettering quantity situation of identical compression with patent 03227049.6, two piston motions of the latter equate with master piston motion distance of the present utility model apart from sum, that is to say two crankshaft eccentrics of the latter apart from half as large with the throw of eccentric of main crankshaft of the present utility model, the work done of main piston of the present utility model like this institute be two bent axles of latter sums of doing work; And sub-piston is at mixed gas explosion time also acting simultaneously, as seen acting is largely increased, reach the effect of energy-saving and emission-reduction, be arranged at the main piston top because of the porting position again, the auxiliary steam cylinder top is provided with spark plug or oil nozzle, make the gas mixing in the master cylinders more even, cause combustion of mixed gas more thorough.

Description of drawings

Below in conjunction with accompanying drawing embodiment is described:

Accompanying drawing 1 is this machine crankshaft piston crank mechanism partly cut-away schematic representation.

Accompanying drawing 2 is the major and minor piston cycle of this a machine mobile position schematic representation.

Embodiment

The utility model removes by body, distribution device and intake and exhaust device, fuel supply system, lubrication system, cooling system, outside electrical system and starting arrangement are formed, also has main piston (3), sub-piston (4), master connecting rod (5), slave connecting rod (6), main crankshaft (7), secondary crankshaft (8), flywheel (9,10), master gear (11), pinion (12), carrier gear (13) and axle (14), master cylinders (2), auxiliary steam cylinder (16) is connected, wherein be equipped with main piston (3) and sub-piston (4) respectively, main crankshaft (7) and secondary crankshaft (8) are positioned on respectively in the crankcase of body (1) two ends, master connecting rod (5) connects main piston (3) and main crankshaft (7), slave connecting rod (6) auxiliary connection piston (4) and secondary crankshaft 8), main crankshaft (7) external part is equipped with flywheel (9) and gear (11), secondary crankshaft (8) external part is equipped with flywheel (10) and pinion (12), master gear (11) radius is the twice of pinion (12) radius, master gear (11) and pinion (12) and axle (14) gear (13) engagement, master cylinders (2) top is provided with porting (15), be equipped with cylinder head above the porting, the auxiliary steam cylinder top is provided with spark plug or oil nozzle.

Working procedure of the present utility model is: main piston (3), sub-piston (4) are at top dead center, the intake valve of inlet and exhaust valve during suction stroke (15) is opened, exhaust valve closing, main piston (3), sub-piston (4) be simultaneously to the lower dead center motion, and when main piston (3) moves to a half, sub-piston (4) has moved to lower dead center, when main piston (3) when continuing to move to lower dead center, sub-piston (4) has been got back to top dead center, and this moment, IC Intake Valve Closes was finished suction stroke; Main crankshaft (7) 180 degree that turned round, secondary crankshaft (8) 360 degree that turned round, main piston (3) move once, and sub-piston (4) moves secondary.Enter compression stroke, main piston (3) moves to cylinder one half toward top dead center, and sub-piston (4) is from the top dead center lower dead center that moved down, and when main piston (3) up moved on to top dead center again, sub-piston (4) lower dead center had again moved to top dead center; While compressed mixed gas, when main piston (3) spark ignitor mixed gas when moving to top dead center, or nozzle sprays into fuel oil, and mixed gas blast at this moment promotes main piston (3), sub-piston (4) moves from top dead center toward lower dead center, drives the major-minor crankshaft rotating and begins acting; When main piston (3) moves on to master cylinders one half, sub-piston (4) has moved on to lower dead center, when main piston (3) when moving on to lower dead center, sub-piston (4) has moved on to top dead center again, at this moment finished expansion stroke, this moment, exhaust valve was opened, enter exhaust stroke, main piston (3) moves on to master cylinders one half from lower dead center, sub-piston (4) has moved on to lower dead center from top dead center, and main piston (3) is when continuing to move to top dead center, and sub-piston (4) has moved on to top dead center from lower dead center, waste gas is discharged, finish a work cycle like this.As seen main crankshaft (7) rotation two all main pistons (3) are reciprocal four times, and secondary crankshaft (8) rotates four circles, reciprocal eight times of sub-piston (4).So go round and begin again.
