Volvo’s enhanced D13 turbo compound engine is now standard on all Volvo VNL models, including day cabs.
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 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.
Cylinder deactivation can reduce NOx emissions through hotter exhaust temperatures and allow more efficient engine operation on fewer cylinders under low-load conditions.
Dialing in some basic fuel-economy parameters to your engine settings can easily save 5% in fuel. Dig a little deeper into the ECM and even more savings are possible.
The 2021 Paccar MX-11 and Paccar MX-13 engines for Kenworth’s Class 8 truck lineup feature re-designed internal components to enhance fuel economy.
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.
Cummins will take over the development, production and delivery of medium-duty engines for Daimler Trucks and Buses around the world by the second half of the decade.
Amy Boerger now heads up Cummins' North America region for On-Highway as vice president and general manager, North America.
For vehicles being put back into service after a prolonged period — particularly in wintertime — fleets should follow these best practices when replacing diesel exhaust fluid (DEF) and engine oil to avoid mechanical issues and keep vehicles running smoothly.
