Any illusions that motor development would at least pause after completion of the Tier 4 Final phase-in were dispelled with Deutz debuting four new diesel engines at CONEXPO-CON/AGG in Las Vegas. Expanding its portfolio from 2.2 to 18 liters, Deutz introduced two four-cylinder models, headed by the 135-200 hp TCD 5.0.
Slated for worldwide distribution in 2019 to meet the next EU Stage V emission standard, the compact TCD 5.0 produces 656 lb ft of torque via a design that uses less pipework and fewer components. It's counterpart four-cylinder TCD 9.0 targets wheel loaders and excavators with its 300-400 hp, and more than 1,250 lb ft of torque.
