Abstract

A piston type internal combustion engine having a fixed position stub shaft mounted on a base. The piston, piston pin and piston rod rotate about this fixed position shaft. The piston assembly does not reciprocate. The cylinder block assembly is mounted to an output shaft whose center line does not coincide with the center line of the axis of the fixed position shaft such that it is offset from the fixed position shaft. The block assembly consists of cylinders, end cap, air intake shroud and exhaust collecting hood. The cycle of combustion is two, three or four cycle regulated by the fuel injection and/or spark plug firing sequence. Air is drawn through a filter into a turbo charge type air intake shroud. Air is accelerated through openings in the cylinders and pistons. Fuel is pumped through the output shaft and to the fuel injectors. Exhaust is dispatched to a rotating collector having a labyrinth type seal, then to a non-rotating hood attached to the base and through an exhaust port.

Claims

1. An internal combustion engine comprising:

a fixed position shaft mounted on a base;

a piston assembly mounted for rotation about the axis of said fixed position shaft;

a power output shaft having a center line axis that is off-set mounted from the center line axis of said fixed position shaft;

a cylinder block housing fixedly mounted to said output shaft, said housing having an affixed cylinder block assembly including fuel ignition means mounted therein;

said piston assembly comprised of a split type piston rod and a straight type piston rod each having piston pins at first ends for rotatable mounting to associated pistons, said split type piston rod at the other end thereof receiving the other end of said straight type piston rod such that respective apertures are aligned for rotatably receiving said fixed position shaft; and

said piston assembly is accommodated in said cylinder block housing.

2. The engine of claim 1 wherein the timed firing of said ignition means simultaneously rotates said piston rods about respective piston pins and about said fixed shaft thereby to rotate said cylinder block housing and said offset mounted output shaft.

3. The engine of claim 2 wherein fuel is provided to said pistons through a channel in said output shaft.

4. The engine of claim 3 wherein lubrication to said piston pins is provided through channels fed by a channel in said fixed shaft.

5. The engine of claim 1 wherein said piston assembly does not reciprocate.

6. An internal combustion engine comprising:

a fixed position shaft mounted on a base;

an output shaft having a center line axis that does not coincide with the center line axis of said fixed shaft;

a piston assembly including first and second piston rods having first ends rotatably mounted to said fixed shaft and second ends rotatably mounted to first and second pistons;

a cylinder housing including first and second cylinders having first and second spark plugs, said cylinders configured for receiving said first and second pistons respectively, said cylinders affixed within said housing and said housing affixed to said output shaft;

said piston assembly is accommodated in said cylinder block housing; and

whereby timed firing of said spark plugs causes said housing to rotate thereby rotating said output shaft.

7. The engine of claim 6 wherein fuel is provided to said pistons through a channel in said output shaft and lubrication to said piston pins is provided through channels

8. The engine of claim 7 wherein the injection of said fuel and the firing of said firing of said spark plugs is timed by a timing distributor thereby providing for coordinated fuel injection and firing sequence.

9. The engine of claim 8 further including:

exhaust means for exhausting combustion gases from said engine, said exhaust means including an exhaust collector with an exhaust port fixedly mounted to said base and an exhaust hood fixedly mounted to said cylinder housing, said exhaust hood having a labyrinth seal for transmitting said gases to said exhaust collector.

10. An internal combustion engine comprising:

a base mounted fixed support shaft and an output motor shaft, said support shaft supporting a rotatable piston assembly thereon and said motor shaft fixedly connected to a cylinder housing;

said output motor shaft having a center line axis that does not coincide with the center line axis of said support shaft;

said piston assembly including a split piston rod and a straight piston rod engaged at first ends and having aligning apertures for rotatably receiving said support shaft, said piston rods at second ends rotatably connected to respective pistons;

said cylinder housing configured for encompassing said piston assembly and having an affixed cylinder block assembly including fuel ignition means mounted therein.

11. The engine of claim 10 wherein timed firing of said ignition means simultaneously rotates said piston rods about respective piston pins and about said fixed shaft thereby to rotate said cylinder block housing and said offset mounted output shaft.

12. The engine of claim 11 wherein fuel is provided through a channel in said output shaft and to a piston fuel injection system.

13. The engine of claim 11 wherein lubrication to said piston pins is provided through channels fed by a channel in said fixed shaft.

14. The engine of claim 10 further including:

exhaust means for exhausting combustion gases from said engine, said exhaust means including an exhaust collector with an exhaust port fixedly mounted to said base and an exhaust hood fixedly mounted to said cylinder housing, said exhaust hood having a labyrinth seal for transmitting said gases to said exhaust collector.

15. The engine of claim 12 wherein the injection of said fuel and the firing of said firing of said ignition means is timed by a timing distributor thereby providing for coordinated fuel injection and firing sequence.

16. The engine of claim 14 wherein said cylinder housing includes an air inlet port.

17. The engine of claim 16, further comprising means for controlling the compression ratio of the cylinders by varying the air provide into the cylinder block of said cylinder housing.

18. The engine of claim 13 wherein lubrication to said piston pins includes radially extending grooves for lubricating purposes.
