In response to the global engine suppliers’ drive to minimize weight and space impact on the vehicle, Jacobs says its engineers continue to focus on new ways of integrating the braking function into the valve train. The Bridge Brake represents the most recent extension of this effort. Jacobs says this new lightweight design provides excellent retarding performance with zero valve train height increase. The Bridge Brake also is suited for small-displacement engines and other applications where packaging space is at a premium, Jacobs says.
This braking system, which was first launched on the Hyundai 10L engine, replaces the standard exhaust valve bridge with a braking valve bridge. Based on Jacobs’ Lost Motion know-how, the company says traditional valve train componentry is maintained, while allowing new complex valve motions to be achieved.
