Description
Technical field
The present invention relates to a kind of fuel oil h type engine h, particularly one kind efficiently to be pushed away in cylinder using fuel oil blast
Power, adjustable compression ratio, the high fuel-efficient engine that multiple fuel can be used.
Background technology
An only moveable piston in current fuel engines cylinder, it is moved back and forth in cylinder, passes through company
Bar crank mechanism become rotation power output, it by air inlet, compress, light blast and exhaust four impulse strokes form.Its
In, when the top dead-centre of piston movement to cylinder head, gas is compressed to volume minimum, i.e. compression ratio highest, this moment point
Explosive thrust caused by combustion gas body is by maximum, but now the connecting rod with piston and bent axle are in a straight line, connecting rod and song
The torque arm length very little of between centers, even zero, thus the torque very little obtained on bent axle, it is the late ignition that this can only be appropriate,
Treat that connecting rod turns over top dead-centre certain angle, when having certain torque arm length between connecting rod and bent axle, then light a fire and promote bent axle to increase
Torque, this certainly will just reduce the compression ratio of gas volume, make fuel oil utilization ratio low.
The content of the invention
It is big in the torque arm length of connecting rod and bent axle the technical problem to be solved in the present invention is to provide a kind of high fuel-efficient engine

Embodiment
Be as shown in Figure 1 prior art engine, including cylinder 1, moved reciprocatingly in cylinder 1 main piston 2, connect
The connecting rod 3 of main piston 2, the bent axle 4 of motion and the spark plug 11 and atomizer 12 positioned at the top of cylinder 1 are driven by connecting rod 3, when
When main piston 2 moves to top in cylinder 1, the oil spout of atomizer 12, the igniting of spark plug 11 are exploded, and then promote piston 2
Move downward in cylinder 1, and then moved with dynamic crankshaft 4, compression ratio is most in cylinder 1 for piston 2 when piston 2 is in top dead centre
Gao Shi（Compression ratio is the ratio between cylinder total volume and combustion chamber volume）, now the ignition energy of spark plug 11 discharge maximum outburst energy
While amount is to turn into the power output of engine, but to keep high compression ratio, but make the arm of force between connecting rod 3 and bent axle 4
Length very little even zero, and then the torque of bent axle 4 is low, reduces engine performance.If it is desired that between connecting rod 3 and bent axle 4
Torque arm length increase will move down piston 2, this cannot keep high compression ratio.
As in Figure 2-4, it is a kind of high fuel-efficient engine of the present invention, including cylinder 1, is moved reciprocatingly in cylinder 1
Main piston 2, the connecting rod 3 being connected with main piston 2 and the bent axle 4 that rotation is driven by connecting rod 3；The main piston 2 in the cylinder 1
Top, which has additional, can coordinate main piston 2 equally to make the auxiliary piston 5 to pump, and auxiliary piston 5 is driven by transmission mechanism 6
Motion, and spark plug 11 and atomizer 12 are located at the auxiliary piston 5 and main piston 2 when auxiliary piston 5 is in bottom dead center position
Between；When main piston 2 moves upwards, the same motion upwards of auxiliary piston 5, then main piston 2 moves downward around top dead centre, auxiliary
Piston 5 is helped and then to move downward, when auxiliary piston 5 moves to lower dead center, the oil spout of atomizer 12, the igniting blast of spark plug 11,
The impulsive force of blast moves downward main piston 2, and at this moment auxiliary piston 5 keeps locked not motion state using transmission mechanism 6, from
And make connecting rod 3 and bent axle 4 has high compression ratio is also maintained while the long arm of force.Specifically as shown in Figure 5,6, shown in Fig. 5
P1 is that cylindrical implosion fries thrust, and L1 is torque arm length, and torque caused by its bent axle 4 is P1 × L1, and the P2 shown in Fig. 6 is cylinder
Interior explosive thrust, L2 are torque arm length, and torque is P2 × L2 caused by its bent axle 4, as P1=P2, and during L1 ＜ L2, shown in Fig. 6
Torque on bent axle 4 will be bigger than the torque on bent axle 4 shown in Fig. 5, i.e. P2 × L2 ＞ P1 × L1.So greatly improve
The operating efficiency of engine, engine can be made just to reach same operating efficiency using less oil, the function with fuel-economizing.
Described spark plug 11 and atomizer 12 is arranged on the cylinder wall of cylinder 1.
As in Figure 2-4, the transmission mechanism 6 can be electric motor, by electronic module control auxiliary piston 5 move Lai
Coordinate main piston 2 to move, or the transmission mechanism 6 can be designed as gear mechanism.It can make institute by adjusting transmission mechanism 6
The top dead centre and bottom dead center position for stating auxiliary piston 5 change, and then change the gas compression ratio in cylinder, make the high fuel-economizing of the present invention
A variety of class A fuel As can be used in engine, such as：Gasoline, diesel oil, oil gas can be used.
The transmission mechanism 6 is preferably designed as cam link mechanism, including telescopic auxiliary connecting rod 61, when advise it is convex
Wheel 62 and when advise chain 63, when described advise chain 63 be connected to bent axle 4 and when advise cam 62 between, by the rotation of bent axle 4 come band
Rule cam 62 rotates when dynamic, when advise the rotation of cam 62 and then drive auxiliary connecting rod 61 flexible, enable the main work of the cooperation of auxiliary piston 5
The motion of plug 2.
Wherein, the auxiliary connecting rod 61 is designed as height-adjustable structure, by the benchmark for changing auxiliary connecting rod 61
Point 611（Fixing point）Position, the top dead centre, bottom dead center position and stroke of auxiliary piston 5 is set reasonably to be adjusted, or will
The cam lever structure that cam 62 is designed as having multiple different structure cams is advised when described, is matched somebody with somebody by the cam for adjusting different structure
Auxiliary connecting rod 61 is closed to change the bottom dead center position of auxiliary piston 5, and then is made in a kind of high fuel-efficient engine cylinder of the present invention
