As manufacturers continue to drive out cost and meet a worldwide patchwork of regulatory frameworks, the tools for developing those engines are advancing. From showcase prototypes to advanced analytical techniques, suppliers are helping the cause.

“It is an exciting time for commercial engine designers,” said Michael Franke, director, light-duty diesel and commercial engines for FEV. The U.S. Tier 4 Final emissions regulation forced developers to deliver compliance in a shorter-than-normal design cycle. Now that the industry has had an opportunity to optimize Tier 4 Final products, the focus has shifted to longer-term objectives in meeting end-user expectations and responding to competition, according to Franke.

With the excitement are some cautions, especially in the small-engine segment. “While this engine segment was always very cost sensitive, we now see foreign manufacturers [trying] to enter the U.S. with low-cost products,” explained Franke. “China and India are progressing quickly with implementing China VI and Bharat-VI for on-highway applications.” These new OEMs can adapt those technologies to meet off-highway Tier 4 emissions, allowing them to offer off-highway solutions in the U.S. and Europe.
