Description: |
| Abstract:
This invention relates particularly to explosive engines in which the charge is compressed in the motor-cylinder before ignition takes place.
One object is to increase the efficiency of explosive engines of the well-known Otto type, in which the cycle of actions is completed during two revolutions of the crank-shaft, the end particularly in view being to provide means whereby in engines of this particular type it may become possible to take advantage of the establishment of an elastic cushion against the front side of the piston, which shall be compressed during the forward movement of the piston and shall be made to do work by expansion during the return stroke of the piston. Incidentally to the successful development of this portion of the invention and as a result of the peculiar conditions which obtain it has been found both desirable and necessary to provide certain special means for lubricating the piston, which means are also applicable to single-acting engines.
Claims:
l. In an explosive engine, the combination with the cylinder, of a jacket surrounding the cylinder with a space between which communicates with the forward end of the cylinder, the forward end of the cylinder and said space being tightly closed so that the contained gas or gases shall be compressed by the forward movement of the piston to expand and do work upon the piston as it makes its return movement, means to displace the air or gases in said space as the engine is operated, and a cooling device, whereby the air or gas is cooled as it is compressed during the forward stroke of the piston and is returned to contact with the heated cylinder for further expansion by increase of temperature as the piston makes its return stroke, substantially as shown and described.
2. In an explosive engine, the combination with the cylinder, of a jacket surrounding the cylinder with a space between which communicates with the forward end of the cylinder, the forward end of the cylinder and said space being tightly closed, a pipe having its ends respectively connected to the space enclosed by the jacket near the respective ends of the cylinder, a check-valve opening away from the jacketed space in the pipe near the rear end of the cylinder and a check-valve opening toward the jacketed space near the forward end of the cylinder, substantially as shown and described.
3. In an explosive engine, the combination with the cylinder having its forward end, tightly closed, of a chamber communicating with the forward end of the cylinder, a valve controlling the communication between the chamber and forward end of the cylinder, and means for operating said valve at successive movements of the piston, whereby communication is open to permit compression and subsequent expansion of the enclosed gases during certain movements of the piston and whereby said communication is closed during other movements of the piston to hold the gases enclosed in the chamber under compression and to relieve the front of the piston of their pressure, substantially as shown and described.
4. In an engine, the combination with the cylinder having its end closed to permit of compression of the enclosed air or gases by the piston, of a closed chamber communicating with the cylinder and adapted to receive a lubricant, a pipe entering said chamber with its end below the surface of the lubricant therein and having its other end communicating with an opening into said cylinder, and two check-valves in said pipe separated by some distance from each other and both opening from said chamber, substantially as shown and described.
