Abstract
Systems, apparatus, and methods are disclosed that include an internal combustion engine having a plurality of cylinders and at least one camshaft for opening at least one valve associated with the at least one cylinder. The camshaft includes a cam with a cam lobe defining a cam lobe profile having a base circle portion on a base circle of the cam lobe, a main cam lobe portion, and a low lift dwell portion that extends a constant height from the base circle along a substantial portion of the base circle to increase valve opening overlap and cylinder scavenging.
