ENGINE CYLINDER HEAD INTAKE PORT CONFIGURATION

摘要

A cylinder head for an internal combustion engine is disclosed having an intake port geometry configured to reduce fuel puddling and improve fuel atomization. The cylinder head includes a housing having a recess defining a top portion of a combustion chamber. The cylinder head further includes intake and exhaust ports defined by channels extending from the top portion of the combustion chamber to an outer end of the housing. An intake valve is positioned within the cylinder head to control communication of the intake port with the combustion chamber, and an exhaust valve is positioned within the cylinder head to control communication of the exhaust port with the combustion chamber. The intake port further includes a cross-section having a modified D-shape with a single 90 degree corner. The modified D-shape cross-section extends substantially a length of the intake port.
