| 123047000 | VALVED PISTON | 6 |
| 20120234297 | TORQUE MULTIPLIER ENGINES - Torque multiplier engines, and associated methods and systems, are disclosed herein. An internal combustion engine in accordance with a particular embodiment can include a connecting rod operably coupling a pair of opposing pistons. The engine can further include a first bearing coupled to the connecting rod and positioned to engage a first cam groove of an inner cam drum. A second bearing coupled to the connecting rod can be positioned to engage a second cam groove on an outer cam drum. The first and second bearings can translate linear motion of the opposing pistons to rotation of the cam drums. | 09-20-2012 |
| 20130199500 | SYSTEM FOR ADAPTING AN INTERNAL COMBUSTION ENGINE SO THAT IT IS OPERATED USING COMPRESSED AIR OR GAS - The invention relates to the adaptation of an internal combustion engine so that it can be operated using compressed air instead of fuel. A system is provided for operating an internal combustion engine that has at least one cylinder and a reciprocating piston. The fuel and the spark plugs are substituted by a system that uses air or a different compressed gas as a driving force means which is supplied into the combustion chamber through the opening of the spark plug. Said system includes a differential compressor ( | 08-08-2013 |
| 20150107559 | PISTON OF AN INTERNAL COMBUSTION ENGINE - An engine block of an internal combustion engine is disclosed. The engine block may have a piston and at least one gas exchange valve. The piston may have a piston skirt having a first center axis. The piston may also have a piston head delimiting the piston skirt at the top with a diameter D. The piston head may have a piston head edge and a piston head recess with a piston recess wall having a height H. At least one valve pocket may be formed into the piston head edge. The at least one valve pocket may have a valve pocket depth T with respect to the piston head edge. The valve pocket depth T may fulfil the following condition with respect to the wall height H: 0.05 H<=T<=0.5H. | 04-23-2015 |
| 20150114352 | TORQUE MULTIPLIER ENGINES - Torque multiplier engines, and associated methods and systems, are disclosed herein. An internal combustion engine in accordance with a particular embodiment can include a connecting rod operably coupling a pair of opposing pistons. The engine can further include a first bearing coupled to the connecting rod and positioned to engage a first cam groove of an inner cam drum. A second bearing coupled to the connecting rod can be positioned to engage a second cam groove on an outer cam drum. The first and second bearings can translate linear motion of the opposing pistons to rotation of the cam drums. | 04-30-2015 |

| 20120227708 | PISTON AND USE THEREFOR - The invention provides a piston which allows pressure generated downstream from the piston to be used to ventilate a combustion chamber of a cylinder in which the piston is slidingly mounted. The crank assembly to which the piston is connected is operable outside of the cylinder which is sealed at both ends. The crank assembly uses eccentric motion to allow a connecting rod which extends between the piston and the crank assembly to move linearly into and out of the cylinder in sealed manner. The piston includes a valve which allows pressurised gas to flow through the piston. | 09-13-2012 |
