Description: |
| Abstract:
This invention relates to the general class of explosive-engines in which the explosive mixture is formed in the working cylinder or explosion-chamber, a liquid hydrocarbon or a previously-formed gas being introduced into such cylinder or chamber and there mixed with air.
One object of the invention is to provide for the reduction of the temperature of the explosion chamber, and consequently of the fresh charge as it is introduced, so that a higher degree of compression can be reached without ignition and the efficiency of the engine increased.
A further object is to provide for at thorough clearing out of the dead gases from the explosion-chamber after each explosion.
A further object, particularly applicable to engines of this class with which a previously formed gas is made the basis of the explosive mixture, is to guard against the retention of any explosive mixture in the ports or passages leading to the explosion-chamber, such retention of explosive mixture leading to secondary explosions, which, at least, impair the efficiency of the engine, if they do not cause injury to its working parts.
To effect the cooling of the explosion-chamber and the clearing out of the dead gases, a small quantity of Water is introduced into the explosion-chamber in advance of the formation therein of the explosive mixture, the water so introduced being instantly vaporized, absorbing heat and driving out the dead gases which then remain in the chamber. The relative time at which the water is introduced is of the essence of this part of the invention. It has been proposed heretofore to introduce a small quantity of water into the explosion-chambers of engines of this class at or immediately after the instant of ignition, with the idea of utilizing the expansive force of the steam thus generated for power behind the moving piston. Incidentally the vaporization of the water would reduce the temperature within they cylinder; but such reduction reducing the efficiency of the mixture than would the dead gases which have been expelled by it. It will be evident that this part, of the invention is not limited to any particular form of engine or of devices with which it is practiced.
Claims:
l. In an explosive-engine, the combination with an explosion chamber or cylinder having a supply-port and an exhaust-port opened as the piston approaches the limit of its forward stroke, of means to introduce Water into the chamber or cylinder as said ports open, whereby the water precedes the explosive charge.
2. In an explosive-engine, the combination with a cylinder having supply and exhaust ports opened by the piston as it approaches the forward limit of its stroke, and means to discharge water through said supply-port as it opens.
3. An explosion-engine having independent air and gas supply ports terminating in the inner surface of the cylinder-Wall and means to close said ports at their extremities.
4. An explosive-engine having independent air and gas supply ports terminating separately in the inner surface of the cylinder-wall and uncovered by the piston in its forward movement.
