Jacobs Vehicle Systems, a supplier of heavy-duty engine retarding and valve actuation solutions, announced that it has developed a new integrated engine braking technology that integrates the functionality of a standard compression release brake into the ultra-small footprint of a valve bridge.
In response to the global engine suppliers’ drive to minimize weight and space impact on the vehicle, Jacobs says its engineers are focused on new ways of integrating the braking function into the valvetrain. The company says the Bridge Brake’s lightweight design provides excellent retarding performance with zero valvetrain height increase and is suited for small displacement engines and other applications where packaging space is at a premium.
The braking system, first launched on the Hyundai 10L engine, replaces the standard exhaust valve bridge with a braking valve bridge and is based on Jacobs’ Lost Motion experience. The traditional valve train componentry is maintained while allowing new complex valve motions to be achieved, according to the company.
