Abstract

A synergistic combustion engine comprises a crankcase, a crankshaft, a cylinder block, a piston, a connecting bar and a cylinder cover, which is characterized in that the axial center of the crankshaft is arranged at one side of the center line of the axis direction of the cylinder block, the rotating direction of the crankshaft is reverse when the piston works, and the distance of crankshaft sidesway is 0.6-2.4 times than the length of crank. The synergistic combustion engine has advantages of causing rotation angle of the crankshaft pushed by the piston more than 199 degree and increasing the rotation angle when the crankshaft works. The shifting speed of the piston working stroke is lower than the shifting speed of non-working stroke, so the effect is the following of: firstly reducing the speed when the piston works, increasing the output power of the motor more than 10%, reducing the speed when the piston sucks the gas and increasing the maximum rotary speed, secondly improving the speed when the piston compresses the gas, reducing the minimum rotary speed of the motor, reducing the idling of the motor and saving oil more than 10%, thirdly increasing the working time, reducing the crankshaft quality, removing inertia flier, simplifying the structure and reducing weight and cost.

Description

The synergy internal-combustion engine

Technical field

The present invention be more particularly directed to a kind of synergy internal-combustion engine.

Background technique

The working principle of internal-combustion engine is to utilize fuel to burn the heat energy that produces in cylinder combustion, promotes piston by when gases are heated, they expand and moves, and is delivered to bent axle through connecting rod again and makes its rotation acting.The bent axle axle center of traditional combustion engine is positioned on the longitudinal center line of cylinder block, and piston is when acting, and bent axle rotates 180 °, and acting finishes when the piston arrives lower dead center.The internal combustion engine working application time of this structure is short, driving crank angle degree is little when doing work, make the internal-combustion engine output power not ideal enough, it is abundant inadequately that piston sucks gas, limited the maximum (top) speed of internal-combustion engine, the Piston Compression gas velocity is slow, limited the minimum speed of internal-combustion engine, oil-saving effect is bad; Because piston connecting rod and crank when upper and lower stop are located on the same line, therefore need on bent axle, be equipped with inertial flywheel, drive bent axle by inertial force and be rotated further, increase bent axle weight and be equipped with inertial flywheel, reduced engine efficiency, made overall structure become complicated again.

Summary of the invention

The objective of the invention is to solve the problems referred to above that prior art exists, a kind of synergy internal-combustion engine is provided, this synergy internal-combustion engine promotes crank angle Du Keda more than 199 ° by connecting rod when piston does work, thereby prolong the working application time of bent axle, but increasing combustion engine output power, make internal-combustion engine suction gas more abundant, increase maximum engine speed, piston arrives after bottom dead center, bent axle continuation rotation is no more than 161 ° just can make piston reset to top dead center, can reduce engine idle, save fuel oil; Can reduce bent axle weight, the cancellation inertial flywheel, simplified structure reduces the motor cost.

The present invention be achieved in that it by crankcase, be located at bent axle, cylinder block on the crankcase, be located at piston in the cylinder block, connect the piston and the connecting rod of bent axle and the cylinder head that is located on the cylinder block and constitute, its special way is: the sense of rotation of bent axle that described bent axle axle center is positioned at cylinder block longitudinal center line one side and sidesway direction when doing work with piston is opposite, and the distance of bent axle sidesway is 0.6～2.4 times of crank length.

Above-mentioned synergy internal-combustion engine, described connecting rod are broken line or curved shape, in case bent axle connecting rod scratching cylinder block inwall when rotating.

Advantage of the present invention is: because the bent axle axle center is positioned at cylinder block longitudinal center line one side and bent axle sidesway distance 0.6～2.4 times for crank length, the angle that promotes the bent axle rotation when making the piston acting can reach more than 199 °, the angle of bent axle and cylinder is more reasonable, has increased moment of torsion; Increased the angle of swing of bent axle under the identical situation of piston working stroke, the piston working stroke is slower than non-working stroke travelling speed, and then produces following effect:

Speed when 1, reducing the piston acting, can utilize the bloated swollen power of gas more fully, compare with traditional combustion engine, can make the identical engine output of volume of cylinder increase more than 10%, reduced the speed when piston sucks gas, can make air-breathing more fully, increase maximum engine speed and power;

2, piston arrives after bottom dead center, bent axle continuation rotation is no more than 161 ° just can make piston reset to top dead center, has improved the speed of Piston Compression (containing exhaust) gas, and the motor minimum speed is further reduced, thereby the reduction engine idle, fuel-economizing is more than 10%;

3, bent axle acting corner has prolonged working application time greater than non-acting corner; For four cylinder engine, no matter piston position all has other cylinder power is provided in top dead center and lower dead center, thereby reduces the bent axle quality and cancelled inertial flywheel, structure is more simplified, and reduced cost.

Fig. 2 is the structural representation of the present invention's (piston is in lower dead center);

Fig. 3 is the structural representation of bent axle among Fig. 1.

Among the figure: crankcase 1, bent axle 2, cylinder block 3, piston 4, connecting rod 5, cylinder head 6, intake valve 7, exhaust valve 8, spark plug or oil sprayer 9, gear 10.

Embodiment

As shown in the figure, the present invention has a crankcase 1, bent axle 2 is installed on crankcase 1, be provided with gear 10 at bent axle 2 one ends, on crankcase 1, be supported with cylinder block 3, in cylinder block 3, be provided with piston 4, piston 4 is connected with bent axle 2 by connecting rod 5, connecting rod 5 is broken line or curved shape, and present embodiment is example with the curved shape, in case bent axle 2 connecting rod 5 scratching cylinder block 3 inwalls when rotating.The sense of rotation of bent axle that described bent axle 2 axle center are positioned at cylinder block 3 longitudinal center lines, one side and sidesway direction when doing work with piston is opposite, and the distance of bent axle sidesway (being the perpendicular distance of bent axle axle center and cylinder block longitudinal center line) is 0.6～2.4 times of crank length.On cylinder block 3, be fixed with cylinder head 6, intake valve 7 and exhaust valve 8 are installed on cylinder head 6, spark plug or oil sprayer 9 are being installed between intake valve 7 and exhaust valve 8 on the cylinder head 6.

During work (is example with the four-stroke gasoline engine), starter motor drives crankshaft rotating by gear transmission, drive piston 4 by connecting rod 5 and move down by top dead center, intake valve 7 open carry out air-breathing, air-breathing end when piston 4 moves to lower dead center, intake valve 7 is closed; Bent axle 2 continues rotation, promote the mixed gas in the piston 4 pressurized gas cylinder bodies 3, when piston 4 moves closer to top dead center, light compressed mixed gas by spark plug 9, gas is fiercely expanded promote piston 4 and do work, in piston 4 descending processes, promote bent axle 2 rotations and reach more than 199 °, prolonged the working application time of bent axle 2.
