摘要： A control system for a variable stroke free piston engine (110), sets the ignition timing as a function of measured piston velocity. This velocity proportional ignition (524) system provides spark advance on a stroke by stroke basis as an aid to starting the engine. Ignition changes over to a piston position based system (531) when the engine is running at steady state. Fuel injection occurs at either piston dead point (522) or is set as a function of piston position (533). Fuel injection is suppressed during cycles where the ports are not uncovered. The control system can also regulate compression ratio based upon piston position or knock sensor (135) data.

摘要： Contrary to the classic reciprocating engine, in a free-piston internal combustion engine according to the invention the combustion chamber (3) does not act directly on the crank piston (2), but on an interposed free piston (1)/gas spring (4) system. As a result, the volumetric work of the combustion gas is converted extremely quickly into kinetic energy of the free pistons shortly after ignition and transmitted to the crank pistons with delay and smoothed. During each power cycle, a non-positive locking apparatus (6) associates a discontinuous power cycle of the free pistons (1) to the continuous movement of the crank pistons (2), which results both in a stable free piston trajectory and in reduced heat transfer to the surrounding walls. The free-piston engine is particularly suited for use in power-generating heaters (micro-CHP) and in hybrid and electric vehicles.
