ROUSH CleanTech has developed a propane autogas engine that is 90% cleaner than the EPA heavy-duty engine standard. This achievement comes after just last year, the company introduced a propane autogas engine that was 75% cleaner than the EPA standard.

With this latest design, ROUSH's propane autogas engine is the first certified by the California Air Resources Board (CARB) to meet optional low oxides of nitrogen emission standard for heavy-duty engines, according to the company.

The new CARB certification covers the 6.8L V-10 3-volt propane autogas engines for Class 4-7 vehicles. Installation of the optional ultra-low NOx engines has begun with some 2018 Ford commercial vehicles and Blue Bird Vision propane school buses.

Class 4-7 medium-duty trucks and buses equipped with ultra-low NOx engines are expected to be very competitive in seeking funding from the Volkswagen Environmental Mitigation Trust settlement.

Turning Connected Vehicle Data Into Decisions That Matter

Fleet leaders have more data than ever, but turning that data into clear, actionable decisions remains a challenge. This white paper shows how leading organizations are using connected vehicle data to improve safety, reduce costs, and optimize fleet performance. Learn how to turn insight into action across your fleet.

Are You Tracking Your Fleet's True Total Cost of Ownership?

Bobit Business Media surveyed 190 fleet professionals and found that while most fleets are tracking costs, fragmented systems and data gaps are keeping true TCO visibility out of reach. With rising pressure to control spend in an increasingly volatile environment, the gap between what fleets think they know and what the data actually shows is wider than you might expect. See how your peers are managing costs today and where the industry still has room to improve.
