Abstract
The application relates to a cylinder head offset chamfer design. An engine includes a cylinder block and a cylinder head assembly. A plurality of cylinders are defined between the cylinder block and the cylinder head. The cylinder head assembly includes a cylinder head, a plurality of channels defined within the cylinder head, the channels fluidly coupled to the plurality of cylinders via a plurality of cylinder ports. Each of the cylinder ports includes a chamfered portion. The cylinder head assembly further includes a plurality of valves, each of the plurality of valves selectively coupled to a respective cylinder port of the plurality of cylinder ports.
