Variable compound rocker system for push rod and overhead camshaft engines

An internal combustion engine having multiple cylinders wherein each cylinder has multiple intake valves, said engine comprising:

• a variable compound rocker system for actuating and varying the intake valve lift events for the multiple cylinders and actuating the exhaust valve lift events for the multiple cylinders, said rocker system comprising:
• a rocker shaft;
• an eccentric ring non-rotatably attached to said rocker shaft;
• a primary rocker rotatably attached to said eccentric ring and having an engaging surface disposed therefrom, said primary rocker adapted to actuate a secondary rocker;
• said secondary rocker rotatably attached to said rocker shaft and positioned generally adjacent to said primary rocker and having a roller disposed therefrom in direct constant rolling engagement with said engaging surface of said primary rocker, said secondary rocker adapted to actuate a first intake valve and a second intake valve;
• and
• an actuator assembly in constant rotational engagement with said rocker shaft and adapted to bi-directionally rotate said rocker shaft for changing the attitude of said primary rocker, causing a change in said intake valve lift events.

A motor vehicle having a passenger compartment and a powertrain, said motor vehicle comprising:

• an internal combustion engine having multiple cylinders wherein each cylinder has multiple intake valves, said engine comprising:
• a variable compound rocker system for actuating and varying the intake valve lift events for the multiple cylinders and actuating the exhaust valve lift events for the multiple cylinders, said rocker system comprising:
• a rocker shaft;
• an eccentric ring non-rotatably attached to said rocker shaft;
• a primary rocker rotatably attached to said eccentric ring and having an engaging surface disposed therefrom, said primary rocker adapted to actuate a secondary rocker;
• said secondary rocker rotatably attached to said rocker shaft and positioned generally adjacent to said primary rocker and having a roller disposed therefrom in direct constant rolling engagement with said engaging surface of said primary rocker, said secondary rocker adapted to actuate a first intake valve and a second intake valve;
• and
• an actuator assembly in constant rotational engagement with said rocker shaft and adapted to bi-directionally rotate said rocker shaft for changing the attitude of said primary rocker, causing a change in said intake valve lift events.
