Jacobs releases new high power density engine brake25 May 2018

Jacobs Vehicle Systems has announced 1.5 Stroke HPD, a variation of the HPD (high power density) brake first launched on a demo truck in 2016.

The new option, says Jacobs, gives much higher levels of supplementary braking force than conventional compression release braking, and with less complexity and cost than its Two-Stroke HPD.

“1.5 Stroke HPD is a simpler and more affordable route that will see our customers achieve the same step-change in braking performance as with Two-Stroke HPD, if their engine hardware allows for that,” says Steve Ernest, VP of engineering and business development.

The latest product is said to give up to 40% more braking power at high engine speeds compared with traditional compression release braking, and improvements of up to 100% at low engine speeds

The low rpm benefits are especially important, says Jacobs, as more truck makers focus on engines with higher power density and lower operating speeds, in the pursuit of better fuel economy and lower total cost of ownership.
