According to Jack Horton the Loudmouth was a  turbine because it met the requirement of reacting to a current of fluid, which is subjected to pressure-in this case, high temperature, high pressure, high velocity gases. 据杰克霍顿的Loudmouth是一个涡轮机 , 因为它满足了反应 , 目前的液体,这是受到压力 , 在这种情况下,高温,高压,高流速气体的要求。 A turbine blade or impeller does not necessarily have to be metallic.  It could be steel, wood, or plastic.  In the case of this free piston engine, the spinning impeller is gaseous, when the powerful gas exhaust reaches the special nozzle, it creates a vortex causing its gases to spin at high speed, which is similar to a modern turbine impeller.  Its high powered thrust is achieved because of the vortex phenomenon of spinning gases. 涡轮叶片和叶轮并不一定是金属。这可能是钢材,木材,或塑料。在这个自由活塞发动机的情况下,旋转叶轮是气态,当强大的气体排放达到特殊的喷嘴,它创建1涡造成的气体在高速旋转,它类似于现代涡轮机叶轮。推力 , 其高功率达到由于纺纱气体涡现象。

Most engines have a crankshaft to deliver output. 大多数引擎曲轴提供输出。 The Free Piston Engine does not have a crankshaft and the added complexity of  rods, bearings, complicated lubrication mechanism... 在自由活塞发动机没有曲轴与连杆,轴承,润滑机理复杂 , 增加了复杂性... The Free Piston Engine Consists of little more than the Piston itself which oscillates inside a metal tube (cylinder) generating high volume of heated gas which is used to propel vehicles thus a jet engine. 自由活塞发动机的组成没有什么比活塞本身的振荡金属管内(缸)加热产生的大量气体 , 用于推动车辆因此有更多的喷气发动机。

Originally developed by Charles Gahagen, the engine has only two moving parts. 最初由查尔斯加黑根发达,发动机只有两个运动部件。 The inventor boasted an amazing 50% thermal efficiency (this has been improved upon recently).  Diesel has an efficiency of only 40% and the four cycle gasoline engine is the least efficient with a thermal efficiency of only 30%. 发明人吹嘘惊人的50%热效率(这已改善 , 最近)。柴油有一个只有40%的效率和四冲程汽油发动机是最起码的仅为30%,热效率高效率。

The secret of it's amazingly high efficiency lies in it's design. 它的秘密的惊人的高效率在于它的设计。 Each stroke produces power, a four stroke engine of similar displacement only produces a fourth of the power and is terribly complicated and heavy compared to free piston engines. 每一个冲程发动机产生的能量相比 , 自由活塞发动机,类似的四冲程发动机排量只有产生的权力是可怕的第四和复杂和繁重。

The Tiny Giant 这种微小的巨人



"The cycle occurs about 70,000 time per minute, moving the pistons about 2 inches, and expelling large amount of gases, at high pressures, through the exhaust ports which lead through a contoured tube. The gases are collected in this tube, or after-burner, and are pushed out at high speeds giving it a jet-like thrust. “发生的周期 , 每分钟约7.0万时,移动了2英寸的活塞,并驱逐了大量的气体,在高压下,通过排气口通过一个轮廓管领先。这些气体被收集在此管,或之后,燃烧器,并已在推给它像喷气推力高的速度。

It is the number of moving parts in this engine that is so fascinating. 这是朝着这个发动机零部件的数量是如此迷人。 In reality the only moving parts are the pistons connected by a rod. 在现实中 , 唯一移动的部位是由活塞的连接杆。 Mr Gahagen says some people may count the disc-like valves as moving parts, but these require no lubrication. 加黑根先生说 , 有些人可以指望这样的运动部件阀门的光盘,但这些不需要润滑。 With few parts, the lubrication is easy. 除了少数地区,润滑很容易。 Adding 3% oil to the standard gasolene gives all the necessary lubrication to the piston riding inside a 5 inch steel sleeve." 添加3%的石油标准gasolene给予一切必要的润滑活塞内的5英寸的钢制套管骑。“

"Due to high thrust the Piston Jet Engine can be used where turbo-jets aren't practical. To further increase this thrust and to increase the volume of gases, a metal plate, equally spaced between the walls of the nozzle, would be added. This plates cuts the nozzle into two halves. Water sprayed from a supply line to create steam would increase the thrust of the engine significantly. “由于大推力活塞式喷气发动机可以用在涡轮喷气机是不实际的。为了进一步加强这一势头 , 并增加的排放量,一个金属板,同样喷嘴之间的间隔墙,将增加。这种板被一分为二半喷嘴。水从供应线 , 以产生蒸汽喷射会增加发动机的推力显着。

用活塞驱动空气和燃气的混合物作涡轮机动力,好处何在?燃油效率更高?我看发电用好。

我评论,作为卡车的动力,需要减速比很高的齿轮组,效率和造价都抵消,但作为电力来源,齿轮组简单所以适合电动汽车使用,也可以作低速飞机的动力,一方面发电一方面喷气(电动飞机?)

再有,这个东西有喷气效应,对飞机有用,地面无用。作为地面机,可能速度不高,起步比较肉,如果只用在船上。飞机上只能通过齿轮驱动风扇,结构比涡轮机复杂,所以无用。但作为发电机动力则再好不过。不过电机还需要超级电容之类辅助。
