A discrete switchable variable valve lift, VVL, system comprising: a first switchable VVL rocker arm assembly that selectively opens a first valve, the first switchable VVL rocker arm assembly comprising: a first outer arm and a first inner arm that are pivotally connected at a pivot axle, a first latch pin that moves between a latched position where the first inner arm and first outer arm move together and an unlatched position where the first inner arm rotates relative to the first outer arm; a second switchable VVL rocker arm assembly that selectively opens a second valve, the second switchable VVL rocker arm assembly comprising: a second outer arm and a second inner arm that are pivotally connected at a pivot axle, a second latch pin that moves between a latched position where the second inner arm and second outer arm move together and an unlatched position where the second inner arm rotates relative to the second outer arm; and an actuation assembly having an actuation shaft rotatably driven by a first motor, the actuation shaft having a first lift cam and a second lift cam, the first and second cams (32, 34) selectively moving the respective first and second latch pins (80a, 80e) between the latched and unlatched positions wherein the actuation assembly is configured to selectively and alternatively provide four distinct operating conditions including: a first operating condition wherein the first and second latch pins (80a, 80e) are in the unlatched position; a second operating condition wherein the first latch pin is in a latched position and the second latch pin is in an unlatched position, the first switchable VVL rocker arm assembly switching to internal exhaust gas recirculation (iEGR), reopening the first engine valve; a third operating condition wherein the first latch is in an unlatched position and the second latch is in a latched position, the second switchable VVL rocker arm assembly switching to iEGR reopening the second engine valve; and a fourth operating condition wherein the first and second latch pins (80a, 80e) are in the latched position, the first and second switchable VVL rocker arm assemblies (20a, 20e) both switching to iEGR reopening the respective first and second engine valves (40a, 40e). a first switchable VVL rocker arm assembly that selectively opens a first valve, the first switchable VVL rocker arm assembly comprising: a first outer arm and a first inner arm that are pivotally connected at a pivot axle, a first latch pin that moves between a latched position where the first inner arm and first outer arm move together and an unlatched position where the first inner arm rotates relative to the first outer arm; a second switchable VVL rocker arm assembly that selectively opens a second valve, the second switchable VVL rocker arm assembly comprising: a second outer arm and a second inner arm that are pivotally connected at a pivot axle, a second latch pin that moves between a latched position where the second inner arm and second outer arm move together and an unlatched position where the second inner arm rotates relative to the second outer arm; and an actuation assembly having an actuation shaft rotatably driven by a first motor, the actuation shaft having a first lift cam and a second lift cam, the first and second cams (32, 34) selectively moving the respective first and second latch pins (80a, 80e) between the latched and unlatched positions wherein the actuation assembly is configured to selectively and alternatively provide four distinct operating conditions including: a first operating condition wherein the first and second latch pins (80a, 80e) are in the unlatched position; a second operating condition wherein the first latch pin is in a latched position and the second latch pin is in an unlatched position, the first switchable VVL rocker arm assembly switching to internal exhaust gas recirculation (iEGR), reopening the first engine valve; a third operating condition wherein the first latch is in an unlatched position and the second latch is in a latched position, the second switchable VVL rocker arm assembly switching to iEGR reopening the second engine valve; and a fourth operating condition wherein the first and second latch pins (80a, 80e) are in the latched position, the first and second switchable VVL rocker arm assemblies (20a, 20e) both switching to iEGR reopening the respective first and second engine valves (40a, 40e). a first operating condition wherein the first and second latch pins (80a, 80e) are in the unlatched position; a second operating condition wherein the first latch pin is in a latched position and the second latch pin is in an unlatched position, the first switchable VVL rocker arm assembly switching to internal exhaust gas recirculation (iEGR), reopening the first engine valve; a third operating condition wherein the first latch is in an unlatched position and the second latch is in a latched position, the second switchable VVL rocker arm assembly switching to iEGR reopening the second engine valve; and a fourth operating condition wherein the first and second latch pins (80a, 80e) are in the latched position, the first and second switchable VVL rocker arm assemblies (20a, 20e) both switching to iEGR reopening the respective first and second engine valves (40a, 40e).
