Definitions

the feed pump 2 is preferably designed as an axial pump, since on the one hand such a pump provides the necessary charging even at relatively low speeds of the electric motor 1. provides pressure for the first filling of the combustion chamber 8 and, on the other hand, in the inactive state, that is to say during normal operation of the engine, barely builds up a flow resistance against the combustion air drawn in.
the combustion chamber 8 has an elongated design, as a result of which the purging characteristic is improved and mixing between combustion gas from the previous explosion cycle and fresh working gas is kept particularly low. Since the working gas in the combustion chamber 8 is ignited at atmospheric pressure, the burning speed of the gas is relatively slow. If the gas were therefore ignited only at the burner head, for example, the excess pressure resulting from the combustion of fresh gas parts near the burner head would drive the remaining fresh gas charge into the pump tube 18 faster than the flame front could spread. For this reason, a multi-point ignition device in the form of an ignition rod 7 is used.
An important aspect of the invention is the special design of the inlet valve 16. It must namely be prevented that the combustion gas flowing out of the combustion chamber 8 in the explosion stroke flows tangentially past a drive liquid surface, since this causes drive liquid from the Combustion gas would be carried away and sprayed into the combustion gas, so to speak. Such a spraying of drive liquid into the combustion gas would, however, lead to cooling and a reduction in volume of the combustion gas even during the explosion cycle. The result would be a significant reduction in the efficiency of the engine.
the inlet valve 16 for the combustion gas is arranged at or - seen in the flow direction of the combustion gas - in front of the end of the pump chambers 18 opposite the outlet openings 182 of the pump chambers 18.
the inlet valve 16 for the combustion gas is arranged and designed in such a way that the combustion gas flowing out of the combustion chamber 8 essentially only hits the drive liquid from the front.
