Bloomfield, CT, USA – Jacobs Vehicle Systems®, the world’s leading supplier of heavy-duty engine retarding and valve actuation solutions, announced today that it has recently enhanced its engine braking technology to include engine decompression capability. This technology provides the ability to decompress the engine cylinders for better engine response under a range of new applications. It can also 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 continues to create new technologies such as this decompression device to support our customer’s efforts.
The Jacobs’ prototype bleeder/decompression system is a bolt-on device which holds an exhaust valve open during startup to reduce the amount of torque required to start the engine. Test data confirms that 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.
On October 3rd, 2011, Jacobs will present this new technology in a poster display at the “Directions in Engine-efficiency and Emissions Research” (DEER) conference in Detroit, MI. This poster covers Jacobs’ mechanical bleeder/decompression technology development efforts along with simulation and test results.
