Internal combustion engine with split cylinder and free piston and power generation using the same

An internal combustion engine (100) comprising:

• a first chamber (200) having a pumping means (202) disposed therein, wherein said first chamber (200) is configured to pump air or charge;
• a second chamber (400) having a second piston (402) disposed therein, said second chamber (400) is connected to and in fluid communication with said first chamber (200) and said second chamber (400) is configured to receive air or charge from said first chamber (200) or from a source of compressed air thereof;
• a third chamber (600) having a third piston (602) disposed therein, said third chamber provided with at least one fluid pump (616) configured to pump fluid to operate valves in the internal combustion engine (100), said third piston (602) operatively coupled to said second piston (402) and said third chamber (600) configured to receive a fluid therein and eject said fluid thereout;
• a second locking mechanism (1000) configured to lock and unlock the movement of an elongated element (606) and thereby control the movement of said second piston (402) and/or a first locking mechanism (800) applied on a pipe (610) or a nozzle (610) on said third chamber (600), wherein at least one fluid pump (812, 814) configured to pump fluid to operate valves in the internal combustion engine (100 is provided in said first locking mechanism (800), wherein said first locking mechanism (800) is configured to control the movement of said third piston (602);
• and
• said second locking mechanism (1000) configured to selectively lock the movement of said elongated element (606) including:
• at least one wedge shaped shoe (1002) having a first edge (1002a), a second edge (1002b), and a third edge (1002c);
• a support (1012) extending from inner walls of said second cylinder (404) of said second chamber (400) on which said at least one wedge shaped shoe (1002) pivotally secured at the said first edge (1002a) thereof;
• a cylinder (1010);
• a pressure relief valve (1010a) configured on said cylinder (1010);
• a piston (1008) reciprocally received in said cylinder (1010);
• a connecting rod (1006) having a first end (1006a) pivotally connected at said second edge (1002b) of said at least one wedge shaped shoe (1002) and a second end (1006b) pivotally connected to said piston (1008);
• and
• a groove (1004) having a shape complimentary to the shape of said third edge (1002c) of said at least one wedge shaped shoe (1002) configured on said elongated element (606) to receive said third edge (1002c) of said at least one wedge shaped shoe (1002) therein in a locking mode wherein said cylinder (1010) therein receives a pressurized fluid, thereby displacing said piston (1008) causing a sequence of movements in which said piston displaces said connecting rod (1006) which in turn displaces said second edge (1002b) of the at least one wedge shaped shoe, thereby rotating said at least one wedge shaped shoe (1002) around said first edge (1002a) thereof moving said third edge (1002c) of the at least one wedge shaped shoe into the said groove (1004) in said elongated element (606), thereby locking the movement of said elongated element (606) and hence arresting the movement of said second piston (402);
• and in a non-locking mode, fluid in said cylinder (1010) is drawn out or pushed out by the force on said second piston (402) due to pressure in said second chamber (400), causing a sequence of movements wherein said piston (1008) is displaced towards the wall of said cylinder (1010), which in turn displaces said connecting rod (1006), which displaces said second edge (1002b) thereby rotating said at least one wedge shaped shoe (1002) around said first edge (1002a) thereof, slipping said third edge (1002c) displaced off from said groove (1004), thereby unlocking said elongated element (606) and hence facilitating the movement of said second piston (402) and the third piston (602).
