Claims9
A cylinder head for accommodating an intake valve and an exhaust valve, each valve having a circumferential wall, the cylinder head having a head surface bottom side and comprising:
- a cavity formed as a depression in the head surface bottom side;
- an intake valve accommodating bore formed in the cylinder head, the bore capable of accommodating the circumferential wall of the intake valve;
- an exhaust valve accommodating bore formed in the cylinder head, the bore capable of accommodating the circumferential wall of the exhaust valve.
The invention in accordance with 2 wherein the head includes intake and exhaust bleed holes in the intake and the exhaust bores.
The invention in accordance with 4 wherein the bleed holes of the intake and the exhaust bores each provide a pulsed source of vacuum.
The invention in accordance with 5 wherein the bleed holes of the intake and the exhaust bores each further provide a pulsed source of pressure.
A method for increasing the compression and reducing harmful emissions from an internal combustion engine, the engine having a removable cylinder head, an intake valve and an exhaust valve, a block portion to which the head is attached, and an intake and an exhaust valve, comprising the acts of:
- removing the installed cylinder head from the engine block;
- replacing the installed intake and exhaust valves with replacement intake and exhaust valves, the replacement intake and exhaust valves having a circumferential wall extending above the faces of each of the valves;
- installing a replacement cylinder head on the engine block, the replacement cylinder head comprising;
- a cavity formed as a depression in the head surface bottom side;
- an intake valve accommodating bore formed in the replacement cylinder head;
- an exhaust valve accommodating bore formed in the replacement cylinder head;
- an intake bore liner for fitting into the intake valve accommodating bore;
- and
- an exhaust bore liner for fitting into the exhaust valve accommodating bore.
