Abstract
An internal combustion engine is provided with a roughly concave cylinder head, wherein a ridge descends into the combustion chamber. A first wall is formed from the ridge to a cylinder periphery to form a seat for an air intake valve. A second wall is formed from the ridge to the opposite cylinder periphery to form a seat for one or more exhaust valves. The valves must criss-cross to open/close. The result is a more efficient flow of intake air and exhaust air to and from the combustion chamber which creates more horsepower. A plug compatible cylinder head can be installed on an engine to get added horsepower without a supercharger.
Claims17
A cylinder head comprising:
- an intake valve wall descending into a combustion chamber;
- an exhaust valve wall descending into the combustion chamber;
- said valve walls meeting to form a ridge extending downwardly into the combustion chamber, said ridge defining a vertical axis of the combustion chamber;
- wherein an intake valve and an exhaust valve criss-cross each other to open/close relative to their respective walls, each of said valves having a valve bottom;
- and
- each of said valve bottoms being at an angle to the vertical axis, said angles each being more than 90 degrees, each of said valve bottoms being preponderantly on one or the other side of a vertical plane containing said vertical axis, said vertical pane being aligned with said ridge.
A cylinder head comprising:
- a V shaped depression descending into a combustion chamber;
- a first side of the V shaped depression providing a seat for an intake valve;
- a second side of the V providing a seat for an exhaust valve;
- wherein a segment of each of the intake air and the exhaust air travels in a straight path to and from the combustion chamber respectively without striking the respective valve;
- and
- wherein the intake and the exhaust valves criss-cross each other.
A dual concave head comprising:
- an intake valve wall descending into a combustion chamber;
- and forming a concave intake cylinder head segment;
- an exhaust valve wall descending into a combustion chamber and forming a concave exhaust cylinder head segment;
- said valve walls meeting to form a ridge extending downwardly into the combustion chamber, said ridge defining a vertical axis of the combustion chamber;
- wherein an intake air segment and an exhaust air segment is formed in the combustion chamber under their respective concave segments;
- an intake valve opening and closing against the intake valve wall, and an exhaust valve opening and closing against the exhaust valve wall, and wherein the intake and exhaust valves criss-cross each other in the cylinder head, each of said valves having a valve bottom;
- and
- each of said valve bottoms being at an angle to the vertical axis, said angles each being more than 90 degrees each of said valve bottoms being preponderantly on one or the other side of a vertical plane containing said vertical axis, said vertical pane being aligned with said ridge.
A process to decrease a time of flight of combustion gas through a combustion chamber comprising the steps of:
- forming a dual concave cylinder head with a V shaped depression into the combustion chamber;
- forming an intake valve seat in a first side of the V shaped depression;
- forming an exhaust valve seat in a second side of the V shaped depression;
- forming a criss-crossed arrangement of an intake and an exhaust valve;
- providing a straight path for a segment of intake air into the combustion chamber;
- and
- providing a straight path for a segment of exhaust air from the combustion chamber.
