Roush CleanTech, a leading provider of advanced clean vehicle solutions, has recently obtained certification from the California Air Resources Board (CARB) for their 2023 model-year propane engines, meeting stringent emissions standards at an impressive rate of 0.02 grams per brake horsepower hour. In a significant development, Roush CleanTech has decided to make the ultra-low nitrogen oxide (NOx) emissions package a standard feature on all propane engines, eliminating the previous added-cost option.
According to Roush CleanTech, these engines emit 90 percent fewer NOx emissions than the limits set by the 2023 regulations, making them 60 percent cleaner than California’s 2024 low-NOx standard. Remarkably, this achievement is attained without compromising performance or efficiency, as highlighted by the company.
Todd Mouw, the Executive Vice President at Roush CleanTech, emphasized the significance of this milestone, stating, “Customers can now benefit from Roush CleanTech propane engines with ultra-low NOx emissions at no additional cost. We are on track to meet California’s and the EPA’s emissions standards for 2027 and beyond.” The company’s commitment to environmental responsibility and compliance is evident in its continuous efforts to exceed regulatory requirements.
Fleet operators considering the purchase of 2023 models will have increased opportunities to access state and federal funding programs that incentivize the adoption of near-zero-emission vehicles. These programs include the Clean School Bus Program under the Infrastructure Investment and Jobs Act and the Volkswagen Environmental Mitigation Trust settlement, among others. Roush CleanTech’s CARB-certified engines position fleet operators favorably to avail themselves of these incentives.
