Field of invention:

The field of invention relates to where enormous power is concerned such as racing, heavy load vehicles, locomotive engines, generators, diesel power plants, etc.

Construction of the engine:

Two common exhaust ports (17a, 17b) are provided at the center of the cylinder. There are four inlet valves (10a, 10b, 10c, l0d) and two injector (11a, 1 lb) are provided in the cylinder head. The connecting rod connects the crank and the piston through the bottom cylinder head(15b). The engine cylinder(14) and piston(l) is sealed on both sides to avoid leakage. The sealing is made by expandable ring (16a) in the piston and compression ring(16b) in the bottom of the cylinder. The connecting rod(8) moves in a reciprocating motion and does not oscillate. There are four compression rings (2a,2b, 2c, 2d)and two oil rings (3a, 3b) provided on the piston. The connecting rod (8) moves in a reciprocating motion and does not oscillate. This motion is converted into rotary motion in crank by a sliding mechanism which is similar to scotch yoke mechanism. This sliding mechanism has a slot in connecting rod for crankpin to slide according to the reciprocating motion of the connecting rod.

Working of the engine:
When the piston is in TDC, at the top of the cyHnder the compression stroke ends, the injector sprays the fuel and the power stroke starts. Where as in the bottom of the cylinder the exhaust and the suction stroke happens simultaneously by scavenging process.

The exhaust port is guided by the piston to get the exhaust from top or bottom of the cylinder. When the piston travels from TDC to BDC, The scavenging process starts at the top and the compression stroke starts at the bottom.

When the piston reaches BDC the compression stroke ends and the power stroke starts at the bottom, Meanwhile the scavenging process ends at the top. When the piston moves from BDC to TDC same process occurs as explained above. This cycle routines.

WE CLAIM

1 .A single stroke engine which producesenormous power comprises a double acting piston, a connecting rod with a sliding mechanism, two inlet valves and a injector at each side of the cylinder and two exhaust port at mid of the cylinder .

2. The system as claim in claim 1 where in, the engine produces combust on both sides of the piston , and produces power for every half revolution of crank.

3. The bottom of the piston and bottom head of cylinder is sealed using expandable rings and compressible rings to avoid leakage.

4. Single stroke engine as here in described with reference to the accompanying diagrams.
