Abstract
A tubular roller valve for an internal combustion engine, which includes a hollow tube having at least one hole, the at least one hole being configured to access an air inlet or an exhaust of a cylinder in an engine block, a tubular outer insulator outside of the hollow tube, the outer insulator being fixed to a cylinder head, and a tubular inner insulator inside of the hollow tube. An additional tube between the hollow tube and the outer insulator can serve to operate as a compression release brake.
Claims20
A valve for an internal combustion engine, comprising:
- a completely hollow tube;
- at least one port in the hollow tube, the at least one port being configured to access an air inlet or an exhaust of a cylinder in an engine block;
- a completely hollow tubular outer insulator outside of the hollow tube, the outer insulator being fixed to a cylinder head;
- and
- a completely hollow tubular inner insulator inside of the hollow tube,
- wherein the valve is configured such that air or exhaust passes through a length of the hollow tubular inner insulator parallel to a wall of the hollow tubular inner insulator.
An exhaust valve and engine brake for a four stroke internal combustion engine, comprising:
- a completely hollow tube;
- at least one port in the completely hollow tube, the at least one port being configured to access an air inlet or an exhaust of a cylinder in an engine block;
- a tubular outer insulator outside of the completely hollow tube, the outer insulator being fixed to a cylinder head;
- a tubular inner insulator inside of the hollow tube;
- and
- a tubular brake between the completely hollow tube and the outer insulator, the tubular brake having several combinations of louvers configured for engine brake a corresponding combination of engine cylinders,
- wherein the valve is configured such that air or exhaust passes through a length of the hollow tubular inner insulator parallel to a wall of the hollow tubular inner insulator.
An internal combustion engine, comprising:
- an engine block;
- two or more cylinders in the engine block;
- a cylinder head on the engine block;
- a tubular air valve and a tubular exhaust valve running through a length of the cylinder head, each of the tubular air valve and the tubular exhaust valve comprising:
- a completely hollow tube;
- at least one port in the hollow tube, the at least one port being configured to access an air inlet or an exhaust of a cylinder in an engine block;
- a completely hollow tubular outer insulator outside of the hollow tube, the outer insulator being fixed to a cylinder head;
- and
- a completely hollow tubular inner insulator inside of the hollow tube,
- wherein the valve is configured such that air or exhaust passes through a length of the hollow tubular inner insulator parallel to a wall of the hollow tubular inner insulator, and
- wherein the internal combustion engine has no camshaft and no pushrods.
