Type II valvetrains to enable variable valve actuation

A valvetrain for a type II engine, the valvetrain comprising:

• a valve bridge comprising a center point, a first valve mounting area, and a second valve mounting area;
• a switching rocker arm including a valve end and a pivot end, the switching rocker arm configured to switch between:
• a first configuration in which the switching rocker arm transfers a first valve actuation profile from a first overhead cam lobe to the center point;
• and
• a second configuration in which the switching rocker arm transfers a second valve actuation profile from a second overhead cam lobe to the center point;
• a center capsule connected to the valve end or to the pivot end, the center capsule configured to switch between:
• an active state in which the transfer of a selected valve actuation profile of the first valve actuation profile and the second valve actuation profile is enabled;
• and
• a lost motion state in which the selected valve actuation profile is absorbed;
• a first auxiliary rocker arm including a first auxiliary valve end and a first auxiliary pivot end, the first auxiliary rocker arm configured to transfer a first auxiliary valve actuation profile from a third overhead cam lobe to the first valve mounting area;
• a first auxiliary capsule connected to the first auxiliary valve end or the second auxiliary pivot end, the first auxiliary capsule configured to switch between:
• a first auxiliary active state in which the transfer of the first auxiliary valve actuation profile is enabled;
• and
• a first auxiliary lost motion state in which the first auxiliary valve actuation profile is absorbed;
• a second auxiliary rocker arm including a second auxiliary valve end and a second auxiliary pivot end, the second auxiliary rocker arm configured to transfer a second auxiliary valve actuation profile from a fourth overhead cam lobe to the second valve mounting area;
• and
• a second auxiliary capsule connected to the second auxiliary valve end or the second auxiliary pivot end, the second auxiliary capsule configured to switch between:
• a second auxiliary active state in which the transfer of the second auxiliary valve actuation profile is enabled;
• and
• a second auxiliary lost motion state in which the second auxiliary valve actuation profile is absorbed.
