Jacobs Says Cylinder Deactivation Delivers 2.76% MPG Boost

Cummins says fuel savings of 2.76% were returned in the first SAE J1321 (Society of Automotive Engineers) standardized fuel consumption testing of its new Jacobs cylinder deactivation technology for diesel truck engines.

What Trucking Fleets Need to Know About Engine Brakes

Fleets running downsped drivelines might be missing out on up to half the potential performance of their engine brakes. Here’s how to get the most from the engine brake while improving driver satisfaction and reducing brake wear.

How Cylinder Deactivation Can Help Meet 2027 Emissions Targets

Jacobs Vehicle Systems is demonstrating how controlling NOx in-engine with cylinder deactivation could be a better way to meet 2027 emissions regulations compared to larger, more complex, and exasperating aftertreatment systems.

Don’t Overlook Engine Brake Maintenance

Did you know that when you’re doing an engine overhaul, you also should take the time to tune up the engine brake?

Cummins Buying Jacobs

Cummins is buying Jacobs Vehicle Systems — which today does far more than exhaust brakes — to help it advance on the road to zero emissions.

Where to Now for Diesels?

Despite all the attention being given to electric drivetrains, diesel engines still have a long future ahead of them. Engineering, design and innovation centers have never been busier.

Jacobs, Tula to Accelerate Cylinder Deactivation, Dynamic Skip Fire Development

Jacobs Vehicle Systems and Tula Technology have signed an agreement to accelerate the development of Jacobs cylinder deactivation valve actuation technology in conjunction with Tula’s dynamic skip fire control algorithms.

How CDA Works to Cut Emissions, Improve Efficiency

Cylinder deactivation can reduce NOx emissions through hotter exhaust temperatures and allow more efficient engine operation on fewer cylinders under low-load conditions.

How Optimizing Cylinder Deactivation Cut NOx Emissions 74% in Cummins-Tula Test

Testing of Tula's sophisticated cylinder deactivation control technology on a Cummins engine showed a 74% reduction in nitrogen oxides (NOx) emissions. We talked to Tula's senior engineer about how it works.

Jacobs’ Technology Demonstrates Fuel Economy, Aftertreatment Efficiency

Jacobs Vehicle Systems’ cylinder deactivation technology (CDA) combined next-generation diesel engines has delivered performance-enhancing benefits according to recent independent validation tests.
