The Peterbilt-Cummins SuperTruck, Part 2: More Secrets Revealed

Cummins ISX15 with waste heat recovery from the front-right side

By Jim Park

The Peterbilt-Cummins SuperTruck project achieved almost-unheard-of gains of 68% in freight efficiency over a 24-hour duty-cycle, a 50% improvement in freight efficiency on an 11-hour drive-cycle and a 20% improvement in the thermal efficiency of the engine. How did they do it, and what does that mean?

The Lowdown on the New Low-Viscosity Oils

Kinematic viscosity is what you might envision when thinking of viscosity – gravitational flow. But the new oils will meet viscosity standards measured at high temperatures/high shear conditions.

By Deborah Lockridge

Exactly what is this "high-temp, high-shear" viscosity engine oil standard in the works for the next round of EPA emissions standards, and what are engine makers doing to make sure engines will still be well protected?

Test Drive: Detroit’s Smooth Self-Shifter

This Freightliner Cascadia Evolution is equipped with a Detroit DD13 diesel and smooth DT12 automated mechanical transmission. The van shown here was empty, so we swapped it out  for a heavily loaded flatbed trailer for our evaluation.

By Tom Berg

“Proprietary” is a magic word among truck builders. It describes components of the company’s own manufacture or design that are installed on the company’s own trucks. For truck users, this can be a good thing, because they’re designed to work specifically with a company’s other components.

But Which Fuel?

Daimler's Mark Lampert says diesel and natural gas are the fuels to watch going forward.

By Jim Park

Natural gas. Biodiesel. Algae-based diesel. Hydrogen fuel cells. Dimethyl-ether. Hybrids. There's a virtual smorgasbord of potential fuel sources or supplements for truck and engine makers to choose from. The critical question becomes which one, or which combinations of fuel sources, represent the best path forward.

Watch for Changing Powertrain Technology to Meet Fuel Economy Regs

Kaufman cited the SuperTruck, a project being done with the Department of Energy by Peterbilt, Cummins, Eaton and other partners, talking about powertrain technologies coming down the road.

By Deborah Lockridge

What type of engine systems and parts will you be dealing with in the future? From electric-drive turbos to waste heat regeneration, Derek Kaufman, president of C3 Network, examined powertrain trends during Heavy Duty Aftermarket Week earlier this year.
