BOLESLAW STOSIK, 0F DENVER, COLORADO.
V INTERNAL-COMBUSTION ENGINE.
Application filed May ,2,
To all whom it may concern:
Be it known that I, BOLESLAW S'rosm, a citizen of the Unite-d States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Internal-Combustion Engines; and I do hereby declare the following to be a full; clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates particularly to internal combustion engines which are provided with two working pistons, and use front and rear compression within the cylinder of the engine. I
The first objectof the invention is to cool automatically the combustion chamber from the inside of the engine; the second object is to provide two separate precompression chambers of which chambers one will discharge the precompressed element into the combustion chamber for purposes of scavenging; the third object is to use tubular pistons with ports and a bypass to avoid the necessity of having valves; the fourth object is to create high suction at the inlet ports in order-that hydro carbon oils like kerosene, etc'., may be utilized and satisfactorily vaporized; the fifth object is to arrange for automatic piston lubrication.
These objects are carried out by the construction hereinafter described and claimed, and as shown in the accompanying drawing wherein 1 is the cylinder; 2, a tubular piston forming the chamber Z with the cylinder; 3, a second tubular piston forming the chamber X with the cylinder and the cylinder cover 9; Y, the combustion chamber formed by the two pistons and the cylinder; 4, a container for lubricating oil, provided with a regulating cock 5, 6, piston rod within boss 7 of cylinder 2; 8, rod of piston 3; 10, in-' letport into the chamber Z; 11, a port in the side of piston 2 to register with a port 12, leading into the bypass 13; 14:, a port leading out of bypass 13 into combustion chamber Y; 17 outlet port of combustion chamber Y; 15, inlet port to chamber X; 16, a port in the side of piston 3 to reg ister with a port 16 leading into bypass 13. 18 is an oil container provided with a regulating cock to furnish lubrication for the piston 3 and the cylinder; 19 is a spring 1921. Serial N0. 465,993.
valve provided in the cover of container 4:, and 20 a similar valve for oil container 18.
The operation of the engine is as follows:
X and Z are two separate induction and precompression chambers provided with separate inlet valves respectively and may be charged-with different mixtures; 1 prefer to charge X with a weak mixture capable of combustion or with pure air to scavenge Y therewith, and chamber Z with a concentrated mixture.
The piston 3 creates on its downward stroke a suction in chamber X and at the point when the piston is nearly at its lowest position, it uncovers the port 15. As the suction in X is released very quickly, the charge will rush in so fast-that any vaporized fuel therein will vaporize still more, and the temperature thereof will drop, cooling the inner walls of chamber X; at this point the same suction will draw some lubricating element out of the container 18. As soon as piston 3 covers the port 15 upon its travel upward, the precompression of the trapped charge in X commences, and when ports 16 and 16 register, the precompressed charge is ejected into the bypass 13. At
this instant the piston 2, after having uncovered upon its downward stroke, the outlet port 17, uncovers the bypass port 14, allowing the charge from X and 13 to enter. As most of the gases of combustion have escaped thru 17 the remaining products of combustion are driven out by the entering scavenging charge. Upon the further downward stroke of piston 2 the ports 11 and 12 register, and the trapped and preoompressed charge in chamber Z, similar to the one in X, escapes into 13 and thence into Y thru 14. The pistons approach each other simultaneously, and as soon as ports14 and 17 are covered by the piston 2, the compression in Y commences. The quick inrush into Y of the precompressed charges from X and Z, and the expansion resulting therefrom, will bring about a drop in the temperature of the said charges, which change in temperature will have a cooling efi'ect upon the combustion chamber Y. The annular 'circumferentially arranged space 21 on the floor of the cylinder and within the chamber Z is of suflicient depth to permit of an appreciable collecting of lubricating oil supplied by the container 4:, and is of sufiicient width to allow the bottom part of piston 2 to dip into the said layer of oil; and to transfer it to the inner wall of cylinder 1; upon its upward stroke for its lubrication. v
The description and drawing show that one of the precompression chambers will supply the combustion chamber with a scavenging charge before the second chamber is capable of supplying its respective charge, because the piston 2 uncovers the port 14 before port 11 registers with port 12 of the bypass 13, thus permitting .the charge from X to fill the chamber Y first. The charges will undergo a thorough agitation before being ignited in the combustion chamber and the pistons will be automatically lubricated.
Changes, however, can be made without interfering with the scope of the invention.
What I claim is:
1. In an internal combustion engine the combination with a cylinder having two inlet ports and one exhaust port in the side thereof and a bypass passage in the wall thereof, of two tubular pistons arranged to create three chambers in the cylinder, to cover and uncover the said inlet ports and to register with the said bypass passage thru a port provided in the wall of each piston in order to connect the three chambers for the purpose specified. v

5. In an internal combustion engine the combination with a cylinder having two inlet and one exhaust ports in the side thereof and a bypass passage in the wall thereof which passage is provided with two inlet and one outlet ports, of two tubular pistons arranged to create three chambers in the cylinder, to cover and uncover the said inlet ports of the cylinder, to register with the two inlet ports of the said bypass passage thru ports provided in the walls of thepistons and of which pistons one is arranged to cover and uncover the said exhaust port of the cylinder and the outlet port of the said bypass passage for the purpose specified.
