Item Emissions and engine performance of an ultra-low sulfur diesel fuel in a utility DI diesel engine(2004-12-18) Kim, Namsu; Matthews, Ronald D. (Ronald Douglas); Hall, M. J. (Matthew John)Diesel fuel with an ultra-low sulfur content will soon displace the high sulfur fuel that has been used for a long time. The purpose of this research was to evaluate how ultra-low sulfur diesel (Texas Low Emission Diesel, TxLED) fuel effects on engine performance and emissions. Hence, TxLED was compared to use of conventional 2D on-road diesel in a one cylinder diesel engine. Small diesel engines such as this are used for a variety of applications by the Texas Department of Transportation. According to the results of these experiments, TxLED provide about 12 % reduction in fuel consumption and emissions benefits of about 30-33 % for NOx, about 21-23 % for PM, about 13~25 % for HC, and about 47~66 % for CO depending upon the test cycle. Also at most test points, the maximum torque with TxLED is higher than with 2D. As a result, it is concluded that use of TxLED in small utility diesel engines provides a benefit in emissions, fuel consumption, and performance
