摘要： A free piston engine in which knocking of the engine is prevented by changing the return energy available to move the piston in its compression stroke and hence to vary the compression ratio. The apparatus includes a condition responsive means associated with possible knocking of the engine, which controls some controlling means for varying the return energy. Where the free piston engine employs a bounce chamber for controlling the return energy, the controlling means may be effective to change the pressure in this bounce chamber. Where the free piston engine has two power pistons acting alternately on a single assembly, the pressure ratio may be varied by controlling the amount of fuel admitted into one or more of the power cylinders. The apparatus also contemplates means for changing the return energy if a movable member driven by the piston moves too far with respect to an associated stationary member.
摘要翻译：一种自由活塞发动机，其中通过改变可用于在其压缩行程中移动活塞并因此改变压缩比的返回能量来防止发动机的爆震。该装置包括与可能的发动机爆震相关联的条件响应装置，其控制用于改变返回能量的一些控制装置。在自由活塞发动机采用反弹室来控制返回能量的情况下，控制装置可以有效地改变该反弹室中的压力。当自由活塞发动机具有交替地在单个组件上起作用的两个动力活塞时，可以通过控制进入一个或多个动力缸的燃料量来改变压力比。该装置还考虑了如果由活塞驱动的可动构件相对于相关联的固定构件移动太远则改变返回能量的装置。

摘要： A piston engine comprises a cylinder defining a combustion chamber, a ringless piston reciprocally mounted within the cylinder, the cylinder having means spaced from the combustion chamber and defining a zone of reduced clearance around the piston. This zone-defining means includes means for lubricating the zone to reduce friction. The lubricating means may comprise a gas-flow arrangement, or a bushing formed of self-lubricating material, or both of these features. The cylinder and piston are fabricated from materials having a maximum coefficient of thermal expansion of 30 X 10 7/* C. The engine may include a compressor piston reiprocal in a compressor cylinder which are designed for minimal heat expansion.

摘要： The drive unit uses a free piston engine acting as an energy converter (9), for direct conversion of fuel energy into hydraulic energy via a combustion process. The hydraulic energy is fed to high pressure and low pressure storage systems (10,11) for operation of hydraulic motors (19), for rotation of the driven vehicle wheels (6). The hydraulic motors may be coupled to the driven rear wheels of the vehicle via planetary gearings (21), with control of the vehicle via an accelerator pedal and a brake pedal, coupled to an electronic control device, with integrated recovery of the braking energy.

摘要： The integrated position measurement provides the position of the engine piston and the position of the moving parts of the linear generator is provided by permanent magnets or markings associated with an extension of the piston, detected inductively or optically. The engine may be provided by a 2-stroke diesel engine with direct fuel injection, with additional current extraction via electrodes using the exhaust gas.
