Patent ID: 7017538

Claim:
A method for producing a powerful and efficient internal combustion four stroke engine comprising: mounting a divider ( 2 ) vertically into the engine head ( 1 ) to divide the engine head ( 1 ) to form a U-shaped like passage with an opening for entry ( 3 ) of air and an opening for exit ( 3 A) of air and exhaust gas; using a blower to continuously pump air into the engine head ( 1 ) through the opening ( 3 ) located on the engine head ( 1 ); causing the incoming air (Arrow A) join the opening ( 3 ) to pause a very short duration upon hitting a bend ( 8 ) opposite the openings ( 3 ) and ( 3 A) before being deflected thus causing air to U-turn and travel out (Arrow B) towards the other opening ( 3 A) thereby instantaneously carrying away any exhaust gas evacuated from the combustion chamber ( 16 ); and using a single valve ( 6 ) for the intake of air into and exit of exhaust gas from the combustion chamber ( 16 ) of the cylinder ( 14 ).
