This technology provides the ability to decompress the engine cylinders for better engine response under a range of new applications, Jacobs says. 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, Jacobs says the adoption of start/stop and hybrid technologies will become more prevalent. Jacobs continues to create new technologies such as this decompression device to support its customer’s efforts.
The Jacobs’ prototype bleeder/decompression system is a bolt-on device that holds an exhaust valve open during startup to reduce the amount of torque required to start the engine.
According to Jacobs, test data confirms this reduction in torque leads to a reduction in energy consumed by the starter. This technology provides vehicle retarding, reduced wear and tear on the starting system, improved cold start, reduced battery drain, and less shaking during engine shut-down.
