Following the recommendations of Project 0-4576, the Texas Department of Transportation (TxDOT) began using an ultra-low sulfur diesel fuel, Texas Low Emission Diesel (TxLED), in all of its diesel engines in the fall of 2003. No problems were encountered with any of these engines except that all ten propulsion engines used in the ferries operated by TxDOT's Galveston Ferry Operations (GFO) failed within about six months after switching to TxLED. TxDOT operates other ferries elsewhere, and none of the propulsion engines used in those ferries experienced any problems. Furthermore, each of the GFO ferries has two other diesel engines that are used for auxiliary power generation, and none of those diesel engines experienced any problems. Therefore, Project 0-5532 was awarded to the Center for Transportation Research (CTR) at the University of Texas (UT) to investigate, determine the root cause of the failures, and recommend solutions. / Supplementary Notes: See also PB2008-112277.
