Abstract
A combustion system is provided for an internal combustion engine including a cylinder head and a piston. In one example, a combustion system may include a cylinder head with a second cylinder surface angled relative to a first cylinder surface, an intake port coupled to the first cylinder surface, an exhaust port coupled to the second cylinder surface, and a piston with a first piston surface parallel to the first cylinder surface and a second piston surface parallel to the second cylinder surface.
Claims20
A system, comprising:
- a cylinder head including a first cylinder surface coupled to an intake port and a second cylinder surface coupled to an exhaust port, the second surface angled relative to the first surface;
- and
- a piston including a first piston surface arranged parallel to and vertically in-line with the first cylinder surface and a second piston surface arranged parallel to and vertically in-line with the second cylinder surface.
A cylinder head, comprising:
- a first surface arranged perpendicular to a vertical centerline of the cylinder head and on a first side of the cylinder head;
- a second surface arranged perpendicular to the centerline and on a second side of the cylinder head, the second side opposite the first side relative to the centerline, the second surface positioned vertically below the first surface;
- and
- a third surface angled between the first surface and the third surface.
