AI Technical Summary
Technical Problem
Hydraulically actuated latches in valvetrains for variable valve lift and cylinder deactivation systems are complex and demand excessive oil, exceeding existing supply systems, and electromagnetic actuators face packaging issues when integrated into rocker arms.
Method used
Integrate an electromagnetic latch assembly within the rocker arm, incorporating oil cooling passageways and using dual positional stability to maintain latch states without continuous power, with regulated oil flow rates to manage heat generation.
Benefits of technology
Reduces system complexity and oil demand while effectively cooling the electromagnet, enabling stable valve actuation and deactivation with reduced power consumption and temperature control.
