Abstract

In a piston engine having a piston space, in which a warm gaseous medium is compressed and heated, and having a liquid-injection device by means of which a liquid is injected into the piston space, a positive pressure is produced in the piston engine, i.e. force. The gaseous medium is warmed in a warming chamber arranged outside the piston space. This makes it possible to avoid the production of exhaust gases and to avoid being limited to one fuel.

Description

"Piston engine"

The invention relates to a piston engine with a piston chamber in which a gaseous medium is compressed and heated.

The well-known internal combustion engines (Otto, diesel, Wankel engines, etc.) What is common is that they fuel the engine more or less quickly burn to achieve maximum compression at the highest temperatures. At the high compression an explosion takes place, which causes the trigger the high pressure required to move the motor is generated.

The disadvantage of the known internal combustion engines is, in particular, that they are largely determined in terms of fuel and that they are harmful Generate exhaust gases.

In contrast, the invention is based on the object of a motor of the type mentioned to create, in which it is possible without the generation get along with exhaust gases and with which no commitment to a fuel is required is.

This object is achieved according to the invention by an outside of the A heating chamber arranged in the piston chamber for heating the gas and by means of a liquid injection device, the Liquid in the flask space after introduction of the heated Injects gas.

The piston engine according to the invention works with an externally arranged Heat source. An externally heated gas (e.g. steam) is introduced into the piston chamber, which is compressed by the piston movement and thereby further heated. In the heated gas becomes an evaporable liquid at a predetermined point in time injected, which is immediately under because of the high temperature in the piston chamber Steam formation expands. The expansion of the transitioned into the gaseous state Liquid creates the useful force as more pressure is created than for the pre-compression was consumed.

It is therefore important for the function of the engine that initially the hot gas is passed into the piston chamber and at a suitable later time the liquid is injected. The hot gas is generated outside the engine. Every possible heat source can be used for this purpose, so that it is possible to switch from one primary energy to the other, e.g. B. from a burn to electrical heating in local traffic or within closed rooms.

The engine according to the invention can be operated relatively quietly produce.

In an advantageous embodiment of the invention, the liquid then injected into the piston chamber when the gaseous medium in the piston is approximately is maximally compressed.

The actual generation of the engine power takes place without emissions, since it is according to a further advantageous embodiment of the invention is possible between Heat chamber and piston space to form a hermetically closed circuit. The engine according to the invention can thus form a compact block that is easily replaceable is.
