Jacobs Vehicle Systems, a global manufacturer of diesel and natural gas engine retarding systems and valve actuation mechanisms, will supply compression release engine brakes across the full range of Guangxi Yuchai Machinery Company K Series heavy duty engines.

The long-term deal strengthens a relationship between Jacobs and Yuchai that began in 2012 with the supply of engine brakes for the K10 and K12 engines.

The new agreement sees Jacobs' products specified on both the diesel and natural gas applications of the K5 (YCK05), K8 (YCK08), K9 (YCK09), K11 (YCK11) and K13 (6K13) engine platforms. The compression release engine brakes are being manufactured at Jacobs' Suzhou facility in Jiangsu, China and supplied to Yuchai's Chinese engine manufacturing plants in Yulin, Guangxi and Wuhu, Anhui.

The Jacobs' compression release engine brake takes the load off the truck's foundation brakes, turning the power-producing diesel engine into a power-absorbing air compressor via a compression release mechanism.

It is capable of 85% of the vehicle's braking needs, increasing productivity by maintaining a higher average downhill speed and reducing slowing time/distances on flat land. It can slow a heavily loaded vehicle from 90km/h to 70km/h in 30% less time and distance than wheel brakes alone.

Operators of trucks with Jacobs' compression release engine brake experience significantly reduced brake wear, the elimination of fade due to high temperatures on the friction brakes and a lower total cost of ownership.
