Jacobs Vehicle Systems, a supplier of heavy-duty engine retarding and valve actuation solutions, announced that it has enhanced its engine braking technology to include engine decompression capability, which provides the ability to decompress the engine cylinders for better engine response under a range of new applications. It also can combine the functionality of a bleeder brake, or it can be used in conjunction with a compression release engine brake.

As vehicle and engine manufacturers strive to reduce their impact on the environment and create more energy-efficient trucks, the adoption of start/stop and hybrid technologies will become more prevalent. Jacobs says it continues to create new technologies such as the decompression device to support our customer’s efforts.

The Jacobs’ prototype bleeder/decompression system is a bolt-on device that holds an exhaust valve open during startup to help reduce the amount of torque required to start the engine, which helps reduce the energy consumed by the starter. This technology, according to the company, provides vehicle retarding, reduced wear and tear on the starting system, improved cold start, reduced battery drain and less shaking during engine shutdown.
