传统发动机之所以能够稳定工作， 是由于飞轮的设置和 /或多缸的设置， 使得活塞处于静止状态时， 发动机的整体运动系统仍不停止， 即发动机的整体 运动系统在发动机的整个工作过程中的每个时间点都具有足够的能量克服任 何一个活塞或多个活塞在任一冲程特别是压縮冲程时的阻力，从而保证发动机 的正常工作。 而自由活塞发动机就不同， 当活塞处于极低运动速度或静止状态 时 （即多数情况是活塞处于上止点或下止点附近时）， 自由活塞发动机的整个 运动系统也处于极低运动速度或静止状态。也就是说此时自由活塞发动机所储 存的能量极小甚至为零，所以没有足够的能量来克服维持活塞运动规律所需要 克服的阻力， 因此， 造成 "失火"状态， 影晌自由活塞发动机的正常工作。 然 而， 单纯增加自由活塞的质量， 会使自由活塞发动机产生强烈的振动。 本发明 通过振子和弹性体的设置， 使得发动机在运行过程中， 一部分能量仍储存在弹 性体中， 无论自由活塞发动机的速度处于多么低的状态， 甚至静止状态， 储存 在弹性体中的能量都能克服运行中的阻力， 帮助自由活塞发动机连续稳定的运 动， 进而实现自由活塞发动机的平稳运行。 在本发明中， 在不设弹性体的结构 中， 由于摆杆和销轴的设置， 使得活塞的运动方向和振子的运动方向相反， 所 以可以增加储存的能量， 同时又能减轻自由活塞发动机的剧烈振动。 The reason why the traditional engine can work stably is because the setting of the flywheel and/or the setting of the multi-cylinder makes the overall motion system of the engine not stop when the piston is at rest, that is, the overall motion system of the engine is in the whole working process of the engine. Each time point has sufficient energy to overcome the resistance of any one or more pistons on any stroke, especially the compression stroke, thereby ensuring the normal operation of the engine. The free piston engine is different. When the piston is at a very low speed or at rest (ie, most of the time the piston is near top dead center or bottom dead center), the entire motion system of the free piston engine is also at very low speed or Stationary state. That is to say, the energy stored in the free piston engine is extremely small or even zero, so there is not enough energy to overcome the resistance that needs to be overcome to maintain the law of the piston movement. Therefore, the "fire" state is affected, which affects the normality of the free piston engine. jobs. However, simply increasing the mass of the free piston will cause strong vibrations in the free piston engine. The invention adopts the arrangement of the vibrator and the elastic body, so that part of the energy is still stored in the elastic body during the operation of the engine, no matter how low the speed of the free piston engine is, or even at rest, the energy stored in the elastic body is It can overcome the running resistance and help the free piston engine to continuously and stably move, thus achieving the smooth running of the free piston engine. In the present invention, in the structure without the elastic body, since the swing rod and the pin shaft are arranged, the moving direction of the piston and the moving direction of the vibrator are opposite, so that the stored energy can be increased, and at the same time, the free piston engine can be alleviated. Vibrate severely.
本发明中所谓的距离调整装置可以是机械式， 电动式或液压式。 它的作用 是调整销轴与自由活塞中心线之间的距离， 以实现在活塞行程一定的情况下， 调整摆杆的摆动速度和角度， 进而改变储存在弹性体内的能量的多少， 使自由 活塞可以在不同的速度下工作， 即自由活塞发动机实现负荷响应（也就是相当 于传统发动机在不同的转速下工作）。
本发明所谓的伸縮调整机构也可以是机械式， 电动式或液压式。 它用来调 整振子与销轴之间的距离， 达到调整振子摆动速度和摆动角度的目的， 进而调 整储存在弹性体内及振子内的能量的多少， 同样实现自由活塞发动机实现负荷 响应。 The distance adjusting means in the present invention may be mechanical, electric or hydraulic. Its function is to adjust the distance between the pin shaft and the center line of the free piston, so as to adjust the swing speed and angle of the swing rod under a certain stroke of the piston, thereby changing the amount of energy stored in the elastic body, so that the free piston It can work at different speeds, ie the free piston engine achieves load response (that is equivalent to the traditional engine operating at different speeds). The so-called telescopic adjustment mechanism of the present invention may also be mechanical, electric or hydraulic. It is used to adjust the distance between the vibrator and the pin to achieve the purpose of adjusting the oscillator's swing speed and swing angle, and then adjust the amount of energy stored in the elastomer and the vibrator to achieve the load response of the free piston engine.
