Show LAB RESEARCH SUMMARY: DIESEL FUEL Standardized combustion tests were performed by Battelle Columbus Division in a production diesel engine to determine with certainty the effect of various levels of the additive called Velino Ventures Carbonex Diesel. This diesel engine additive consisted of an organoiron compound diluted in a 2-ethyl hexanol carrier. The influence of two levels of Carbonex Diesel iron (0.04 and 0.08 ppm) was evaluated in a 4-stroke, 6-cylinder, 4300 cubic-inch diesel engine, rated at 1400 brake-horsepower and 1200 revolutions per minute at full load. The diesel engine was operated at about 85 percent of full load to artificially create a particulate emissions problem. The measurable and reproducible results provided the following information: • • • The addition to conventional diesel fuel of 0.04 to 0.08 ppm Carbonex Diesel iron: Reduced CO emissions 7-10 percent, Reduced HC emissions 3-9 percent, Reduced particulate carbon 13-26 percent, Reduced particulate emissions 29-43 percent, Increased combustion efficiency 0.2-0.4 percent, and Had no effect on NOx emissions. Use of Carbonex Diesel is superior to other diesel particulate control technologies in that it does not result in increased NOx emissions or diminished fuel economy. Carbonex Diesel is competitive with other chemical additives for diesel particulate reduction because less of the active metal (iron) is required to accomplish the reduction. |
