Jacobs’ HPD Benefits
Jacobs’ full 2-stroke HPD technologies realize up to 100% performance improvements at low engine speeds compared to traditional compression release brakes or up to 40% improvements at higher engine speeds.
Standard Compression Release
1.5 Stroke HPD
2 Stroke HPD
Natural Gas Engine + HPD Engine Brake
The smaller turbo and compression ratios of natural gas engines negatively impact the brake retarding power by up to 25%. Jacobs' High Power Density Engine Brake makes up for this loss so fleets can still safely haul standard load sizes.
